Abstract
Raw or undercooked freshwater fish consumption contributes to persistent Opisthorchis viverrini infection in Northeast Thailand. This study aims to assess the relationship between misconceptions, unhealthy eating habits, and O. viverrini infection. Data were obtained from the Cholangiocarcinoma Screening and Care Program in Northeast Thailand from 2019 to 2021. Participants were screened for O. viverrini annually over the following 2 years using the Kato-Katz technique. Misconceptions and unhealthy eating habits were assessed through questionnaires. The relationship between these factors and O. viverrini infection was evaluated using adjusted risk ratios (ARRs) and 95% confidence intervals (CIs) from generalized estimating equations under binomial regression framework. Of 5375 participants screened for O. viverrini over 3 years, infection rates were 21.53%, 10.7%, and 4.6% each year, respectively. Out of those, 636 participants responded to questions regarding misconceptions. Results showed that participants who believed in the efficacy of putting lime or red ants in Koi pla (raw fish salad) or eating Koi pla with white whiskey to kill parasites, and early-stage cholangiocarcinoma can be cured, were 41% (ARR, 1.41; 95% CI, 1.03-1.94) and 57% (ARR, 1.57; 95% CI, 1.06-2.33), respectively, more likely to be infected with O. viverrini. Our study confirms that belief in using lime or red ants in Koi pla or eating Koi pla with white whiskey to make it cooked, or early-stage cholangiocarcinoma can be cured, increases O. viverrini infection risk in high-risk populations. Changing health beliefs and eating habits is necessary to reduce O. viverrini infection and its risk to cholangiocarcinoma.

Abstract
Background Individual host susceptibility is believed to be a risk factor in the interaction between the host and the parasite. Since studying time series in humans is limited, animal models are replaced. Aim This study aims to explore and compare the pattern of inflammatory cell types along the biliary tract and their association with proliferative lesions in the early development of cholangiocarcinoma from susceptible and nonsusceptible animal models. Methods Thirty male Syrian golden hamsters and 30 BALB/c mice, serving as the susceptible and nonsusceptible animal models, were used in this comparative study. The animals were infected with 50 Opisthorchis viverrini metacercariae via gastric intubation. At days 1, 2, 7, 14, 28, and 56 postinfection (p.i.), five animals were randomly selected from each group and humanely sacrificed. The hepatobiliary tissues were collected and processed for histopathological study. Histochemical and immunohistochemical staining were applied to differentiate the inflammatory cell types. Kruskal-Wallis and Mann-Whitney tests were applied to assess all semi-quantitative and quantitative variables. The correlation between each variable was also analyzed using Spearman rank at a p-value < 0.05. Results The results demonstrated that mice had different patterns of infiltrating cell types when compared to hamsters. This suggested that the cellular response to the infection in mice occurred earlier than that in hamsters. The response in mice reached its peak at D7 to D14 and then rapidly declined at D28. In contrast, although the inflammatory response in hamsters started slowly, the response reached the peak at D28 and maintained a high level until D56. Significant differences in the number of inflammatory cells between mice and hamsters were seen at D1 (p = 0.047), D7 (p = 0.049), D28 (p = 0.040), and D56 (p < 0.040). Conclusion The inflammatory responses to O. viverrini infection in the nonsusceptible animal model occurred and declined earlier while the response in the susceptible animal model occurred later in a gradual manner. Both rodents are suitable animal models for the studies of opisthorchiasis susceptibility.

Abstract
Opisthorchis viverrini (Ov) infection can cause several disease conditions of the bile duct including hepatobiliary abnormalities (HBAs) and the most severe, cholangiocarcinoma (CCA). Fibrosis occurs when tissues are damaged and normal wound-healing responses are dysregulated. Neutrophils are the first cells to migrate to an infection site to protect the host from intruding extracellular pathogens through a wide range of effector mechanisms such as phagocytosis, production of reactive oxygen species, proteases, or release of neutrophil extracellular traps (NETs). In this work, we used confocal microscopy to assess whether Ov crude antigens can cause release of NETs from neutrophils from Ov-free individuals. We demonstrated for the first time that these antigens could induce release of NETs ex vivo in a dose-dependent manner from neutrophils isolated from Ov-free individuals. Intriguingly, when we measured NETs from neutrophils isolated from Ov-infected patients, we found increased spontaneous production of NETs in patients with HBAs. Interestingly, exposure to Ov crude antigens lowered the level of NETs released by neutrophils from patients with active Ov infection regardless of HBA status. We propose that in the case of acute Ov infection, even when concentration of Ov antigens is relatively low, neutrophils can form NETs. However, when this infection becomes chronic, manifesting as a definite HBA, the levels of NET production are reduced when treated with Ov crude antigens. Excessive production of proinflammatory mediators from these NETs might have effects on the parasites, but may also lead to excessive injury of surrounding tissues resulting in HBAs and may lead eventually to the most severe complications such as CCA.

Abstract
Opisthorchis viverrini is a carcinogenic parasite that can cause bile duct cancer called cholangiocarcinoma. A study of the immune response of this parasite in susceptible and non-susceptible hosts may provide a clue to develop vaccines and immunodiagnostic markers, which are currently not available. Here, we compared the antibody response in susceptible Golden Syrian hamsters and non-susceptible BALB/c mice infected by the liver fluke. In mice, the antibody was detected between 1 and 2 weeks post-infection, whereas it was positive between 2 and 4 weeks post-infection in hamsters. Immunolocalization revealed that the antibody from mice reacts strongly with the tegumental surface and gut epithelium of the worm, while hamster antibody showed a weak signal in the tegument and a comparable signal in the gut of the worm. Immunoblot of the tegumental proteins demonstrated that while hamster antibody showed a broad specificity, mice strongly reacted with a single protein band. Mass spectrometry revealed these immunogenic targets. Recombinant proteins of the reactive targets were produced in the bacterial expression system. The immunoblot of these recombinant proteins confirm the reactivity of their native form. In summary, there is a different antibody response against O. viverrini infection in susceptible and non-susceptible hosts. The non-susceptible host reacts quicker and stronger than the susceptible host.

Abstract
Host mucins have crucial physical roles in preventing the parasitic establishment and maturation, and also in expelling the invading parasites. However, some parasites utilize mucinase enzymes to facilitate the infection. Recently, we have identified a mucinase enzyme of the liver fluke Opisthorchis viverrini, Ov-M60-like-1, which exhibits metallopeptidase activity against bovine submaxillary mucin substrate. Here, we aimed to study the localization of this enzyme in O. viverrini and the bile duct of hamsters using immunohistochemistry and functional analysis by mucin digestion in hamsters and mice tissues. The results showed that Ov-M60-like-1 was detected strongly in the tegument, tegumental cells, vitelline glands and mature eggs with miracidium. Expression in the gut, ovary and testis of the parasite was moderate while parenchyma showed slight colour intensity. In addition, the mucinase was also detected in the host biliary epithelial cells and goblet cells surrounding the worm. The mucinase assay revealed that the Ov-M60-like-1 could digest neutral mucin in the parenchyma, testis and seminal receptacle, but not the mucin in the tegument, tegumental cells and vitelline glands of the worm. The enzyme can also digest mucin in the cholangiocytes and modified the mixture type in the bile duct goblet cells of the infected hamsters, a susceptible host. In contrast, the enzyme was unable to digest neutral, acid and mixture mucin in the bile duct of the mice, a non-susceptible host. These findings indicate that Ov-M60-like-1 may have functions in both housekeeping tasks and host–parasite interactions, especially in modification of host susceptibility.

Abstract
Infection with the food-borne liver fluke Opisthorchis viverrini is the principal risk factor for cholangiocarcinoma (CCA) in the Mekong Basin countries of Thailand, Lao PDR, Vietnam, Myanmar and Cambodia. Using a novel model of CCA, involving infection with gene-edited liver flukes in the hamster during concurrent exposure to dietary nitrosamine, we explored the role of the fluke granulin-like growth factor Ov-GRN-1 in malignancy. We derived RNA-guided gene knockout flukes (ΔOv-grn-1) using CRISPR/Cas9/gRNA materials delivered by electroporation. Genome sequencing confirmed programmed Cas9-catalyzed mutations of the targeted genes, which was accompanied by rapid depletion of transcripts and the proteins they encode. Gene-edited parasites colonized the biliary tract of hamsters and developed into adult flukes. However, less hepatobiliary tract disease manifested during chronic infection with ΔOv-grn-1 worms in comparison to hamsters infected with control gene-edited and mock-edited parasites. Specifically, immuno- and colorimetric-histochemical analysis of livers revealed markedly less periductal fibrosis surrounding the flukes and less fibrosis globally within the hepatobiliary tract during infection with ΔOv-grn-1 genotype worms, minimal biliary epithelial cell proliferation, and significantly fewer mutations of TP53 in biliary epithelial cells. Moreover, fewer hamsters developed high-grade CCA compared to controls. The clinically relevant, pathophysiological phenotype of the hepatobiliary tract confirmed a role for this secreted growth factor in malignancy and morbidity during opisthorchiasis.

Abstract
The liver fluke Opisthorchis viverrini is a foodborne trematode that, in chronic infection, is a leading cause of bile-duct cancer – cholangiocarcinoma. Cats and dogs are acknowledged as reservoir hosts of this parasite. However, this assumption is based on morphological similarity of flukes recovered from these hosts, without any molecular genetic evidence. The aim of this study was to obtain molecular data from O. viverrini eggs present in feces of humans and cats in the same locality in Thanya sub-district, Kalasin, Thailand. The mitochondrial cytochrome c oxidase subunit 1 (cox1) gene was used as the marker for a population-genetic study. A DNA fragment of the cox1 gene was amplified from stool samples and subjected to nucleotide sequencing. Phylogenetic and haplotype network analyses were performed. The cox1 sequences of O. viverrini eggs from humans and cats largely formed separate clades on the phylogenetic trees, with an Fst value of 0.64 (P < 0.05), indicating largely distinct populations in the 2 species. However, 5 samples from cats were placed in the human cluster and 1 sample from a human was placed in the cat cluster. This suggests that host specificity of ‘human’ and ‘cat’ clades is not absolute. These results indicate that there are 2 populations of O. viverrini, one circulates primarily in humans and the other in cats. However, cross-transmission can occur between these 2 hosts. Taken altogether, the population-genetic evidence from this study partially supports the assumption that the cat can act as a reservoir host of O. viverrini.

Abstract
Although Opisthorchis viverrini (OV), lifestyle, and diet co-factors have a relatively high prevalence in the Greater Mekong Subregion (GMS) population, cumulative (0–74) incidence rates of cholangiocarcinoma (CCA) do not reach 5% in this region. Other co-factors must influence, but in this study, we only highlighted positive factors for guiding joint planning to address public health problems at the regional level. Therefore, we aimed to study prevalence and factors associated with CCA incidence focusing only on protective factors. A cross-sectional analytic study was carried out from June to October 2017. Participants with informed consent completed the questionnaires. Descriptive statistics were used to analyze general information. Primary variables were classified into high and low levels by mean. Logistic regression was employed to investigate the correlation between interesting variables and the overall risk level of CCA. The overall prevalence of CCA protective factors of the whole region was knowledge (61.39%), health beliefs (42.32%), prevention behavior (31.93%), and community participation (14.53%). When considering the proportions at a high level, they were 49.53%, 53.72%, 35.37%, and 49.67%, respectively. Significant factors associated with CCA prevention were females with secondary or vocational education, a high level of perceived seriousness and benefits, and community participation. These findings are likely to be helpful for both the public and administrators. First, it can be information for people to be aware of CCA risk. Second, policy-driven authorities at the local or regional level should apply the critical issues from this study for joint planning to sustainably solve regional public health problems.

Abstract
The human liver fluke Opisthorchis viverrini (Ov), the primary risk factor for cholangiocarcinoma (CHCA), is a parasite endemic to southeast Asian countries. With no effective treatments for CHCA currently available, early diagnosis and treatment of Ov infection remains the only practical method for the prevention of CHCA. In this study, plasma phosphoproteomes of patients in the non-Ov infection, non-cholangiocarcinoma subject group (non-OVCCA), the asymptomatic Ov infected group (OV), and the CHCA group (CCA), were investigated to identify potential biomarkers for Ov infection and CHCA. The AKT signalling pathway was found to be up-regulated. Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform (PIK3CB), an upstream signalling molecule, was selected as a potential biomarker and evaluated using indirect enzyme-linked immunosorbent assay (ELISA). Results demonstrated evidence that levels of PIK3CB in both the OV group and CCA group was statistically different compared to the non-OVCCA group (P < 0.01). However, the levels of PIK3CB between the OV group and the CCA group were found not to be statistically different. Sensitivity and specificity for OV using OD450 cut-off at >1.570 was 76 and 72%, respectively. For CCA, sensitivity and specificity using OD450 cut-off at >1.398 was 68 and 76%, respectively. Application of indirect ELISA detecting plasma PIK3CB will be of great benefit for screening of opisthorchiasis and CHCA.

Abstract
Dendritic cells (DCs) are antigen-presenting cells (APC) involved in the initiation of immune responses. Maturation of DCs is characterized by the high expression of major histocompatibility complex (MHC) class II and co-stimulatory clusters of differentiation (CD) 40, CD80, and CD86 molecules. Matured DCs are required for T cell differentiation and proliferation. However, the response of DCs to Opisthorchis viverrini antigens has not yet been understood. Therefore, this study sought to determine the expression of surface molecules of JAWSII mouse DCs stimulated by crude somatic (CS) and excretory-secretory (ES) antigens of O. viverrini. ES antigen significantly induced only mRNA expression of CD80 and MHC class II in JAWSII mouse DCs, while CS antigen promoted up-regulation of both mRNA and protein levels of CD80 and MHC class II, indicating relative maturation of JAWII mouse DCs. Moreover, the secreted cytokines from the co-cultures of O. viverrini antigens stimulated JAWSII DC with naïve CD4+ T cells was determined. Significantly increased levels of immunosuppressive cytokines interleukin (IL)-10 and transforming growth factor beta (TGF-β) were found. The up-regulation of these cytokines may indicate the response of regulatory T cells (Treg) to CS antigen-stimulated JAWSII DC. These findings may lead to a better understanding of the role that DCs play in O. viverrini infection.

Abstract
Cholangiocarcinoma (CCA) is a common hepatobiliary cancer in East and Southeast Asia. The data of microbiota contribution in CCA are still unclear. Current available reports have demonstrated that an Opisthorchis viverrini (OV) infection leads to dysbiosis in the bile duct. An increase in the commensal bacteria Helicobacter spp. in OV-infected CCA patients is associated with bile duct inflammation, severity of bile duct fibrosis, and cholangiocyte proliferation. In addition, secondary bile acids, major microbial metabolites, can mediate cholangiocyte inflammation and proliferation in the liver. A range of samples from CCA patients (stool, bile, and tumor) showed different degrees of dysbiosis. The evidence from these samples suggests that OV infection is associated with alterations in microbiota and could potentially have a role in CCA. In this comprehensive review, reports from in vitro, in vivo, and clinical studies that demonstrate possible links between OV infection, microbiota, and CCA pathogenesis are summarized and discussed. Understanding these associations may pave ways for novel potential adjunct intervention in gut microbiota in CCA patients.

Abstract
BACKGROUND The liver fluke, Opisthorchis felineus, is widely distributed throughout Europe and large parts of the Russian Federation. In Western Siberia, information about opisthorchiasis is lacking although infection may lead to severe liver and bile duct diseases. We aimed to assess the current prevalence of O. felineus infection along with associated risk factors and morbidity in rural Western Siberia. METHODS We conducted a community-based, cross-sectional study in the rural Shegarskiy district, Tomsk Oblast, Russian Federation. All household members (≥ 7 years) present on the survey day were enrolled (n = 600). Two stool samples per person were examined for helminth eggs, using PARASEP (DiaSys Ltd, UK). The number of eggs per gram (EPG) of feces was recorded. Each study participant was interviewed to determine risk factors, using a pre-tested questionnaire. An abdominal ultrasonography examination of liver and bile ducts was performed with a mobile, high resolution ultrasound device. In total, 488 persons completed assessments (two stool samples, completed questionnaires); of those, 436 individuals had an ultrasonography (US) examination. RESULTS We observed a prevalence of O. felineus infection of 60.2%. Significant risk factors for infection were the consumption of river fish (odds ratio from adjusted analysis [aOR] 2.4, 95% CI 1.52-3.95, p<0.001), particularly stock fish (OR from multivariable analysis [mOR] 3.2, 95% CI 2.63-3.80, p<0.001), smoked fish (mOR 1.5, 95% CI 1.24-1.72, p<0.001), frozen fish (mOR 1.6, 95% CI 1.29-2.02, p<0.001), and raw fish (mOR 1.4, 95% CI 1.05-1.84, p = 0.02); and fishing activities (mOR 1.2, 95% CI 1.03-1.43, p = 0.019). Women had a higher risk of infection than men. Infection was associated positively with age and negatively with socio-economic status. The respondents' general awareness of opisthorchiasis was quite high (93.2%), but their knowledge about infection transmission and prevention was insufficient. Children aged 7-18 years old had a lower level of awareness compared to adults. The abdominal ultrasonography results demonstrated a strong association between O. felineus infection and gallbladder stones (mOR 2.8, 95% CI 1.33-6.04, p = 0.007) and periductal fibrosis of intrahepatic bile ducts (mOR 1.9, 95% CI 1.08-3.46, p = 0.026). CONCLUSION O. felineus infection is highly prevalent in rural regions of Western Siberia, and associated with severe hepatobiliary pathology. Identified risk factors will be used to develop a comprehensive targeted O. felineus infection control program.

Abstract
Carcinogenic liver fluke is still an issue of great concern in some countries of Southeast Asia, particularly in Thailand, Cambodia, the Lao People's Democratic Republic, and Vietnam. The infection, caused by Opisthorchis viverrini, is associated to cholangiocarcinoma and is endemic among human populations for whom raw fish is frequently consumed. Prevention and health education are required. Therefore, this study aimed to evaluate the effectiveness of educational intervention to improve knowledge among primary schoolchildren based on animation-assisted education. In this study, 80 participants (40 participants in the experimental group and 40 participants in the comparison group) were selected in 2018. The effectiveness of an interactive animation program in improving the knowledge of students studying liver fluke was determined based on scores on tests given before and immediately after completion of a 4.29-min animated program on the liver fluke life cycle, risk factors, disease, diagnosis, treatment, prevention, and control. Data were analyzed using SPSS-22 via paired t tests and independent samples t tests at a significance level of 0.05. A marked and significant improvement was observed in the immediate posttest compared with the pretest scores. More importantly, the students who had used the animated program achieved a significantly higher score on the final test than the comparison group. The results offered in the first report show that the use of the animated program facilitated education about liver fluke. It is strongly believed that animations are good supplementary learning materials for students, particularly for learning about serious concepts.

Abstract
This article reviews the past and present scientific reports regarding Bithynia spp. focusing on the biology, ecology and life cycle of Bithynia snails and their responses to Opisthorchis viverrini infection. Moreover, new data regarding comparative molecular genomics and proteomic approaches have recently revealed novel molecular components involved in the immune defence responses from Bithynia spp., providing additional perspectives for future studies. Studies on the specific interaction between Bithynia snails and their trematodes will contribute to further understanding the snail-parasite relationship with regards to epidemiology and control of Opisthorchiasis and broaden the scope on comparative immunology of gastropod snails.

Abstract
Opisthorchis viverrini, a human liver fluke, is highly prevalent in Southeast Asia. Definitive diagnosis of infection is usually achieved parasitologically through the discovery of fluke eggs in feces. However, the eggs of O. viverrini are difficult to differentiate morphologically from those of other minute intestinal flukes in fecal samples, even for experienced technicians. The present study developed a label-free optical methodology for analysis of O. viverrini eggs using Raman spectroscopy. Raman features of O. viverrini eggs were reported that can be used as marker bands for the efficient analysis of O. viverrini eggs in fecal specimens. The methodology presented here allows for the rapid detection of O. viverrini egg infection and can be readily and practicably applied in any clinical setting, even those in which a trained parasitologist is not available.

Abstract
Infections caused by Schistosoma haematobium and Opisthorchis viverrini are classified as carcinogenic. Although carcinogenesis might be a multifactorial process, it has been postulated that these helminth produce/excrete oxysterols and estrogen-like metabolites that might act as initiators of their infection-associated carcinogenesis. Current treatment and control of these infections rely on a single drug, praziquantel, that mainly targets the parasites and not the pathologies related to the infection including cancer. Thus, there is a need to search for novel therapeutic alternatives that might include combinations of drugs and drug repurposing. Based on these concepts, we propose a novel therapeutic strategy that combines drugs with molecule antioxidants. We evaluate the efficacy of a novel therapeutic strategy to prevent the formation of putative carcinogenic metabolites precursors and DNA adducts. Firstly, we used a methodology previously established to synthesize metabolites precursors and DNA adducts in the presence of CYP450. Then, we evaluated the inhibition of their formation induced by drugs and antioxidants alone or in combination. Drugs and resveratrol alone did not show a significant inhibitory effect while N-acetylcysteine inhibited the formation of most metabolite precursors and DNA adducts. Moreover, the combinations of classical drugs with antioxidants were more effective rather than compounds alone. This strategy might be a valuable tool to prevent the initiation of helminth infection-associated carcinogenesis.

Abstract
Background The liver fluke Opisthorchis viverrini infects several million people in Southeast Asia. Adult flukes live in the bile ducts of humans, where they cause hepatobiliary pathology, including cholangiocarcinoma. Here, we investigated the potential of extracellular vesicles (EVs) secreted by the fluke and defined recombinant proteins derived from EVs to generate protective immunity in a hamster vaccination-challenge model. Methodology/Principal findings EVs isolated from the excretory-secretory products of O. viverrini and two recombinant EV surface proteins encoding the large extracellular loops (LEL) of Ov-TSP-2 (rOv-TSP-2) and Ov-TSP-3 (rOv-TSP-3) were adjuvanted and used to vaccinate hamsters intraperitoneally followed by challenge infection with O. viverrini metacercariae. The number of adult flukes recovered from hamsters immunized with EVs, rOv-TSP-2, rOv-TSP-3 and rOv-TSP-2+rOv-TSP-3 were significantly reduced compared to control animals vaccinated with adjuvant alone. The number of eggs per gram feces was also significantly reduced in hamsters vaccinated with rOv-TSP-2 compared to controls, but no significant differences were found in the other groups. The average length of worms recovered from hamsters vaccinated with EVs, rOv-TSP-2 and rOv-TSP-3 was significantly shorter than that of worms recovered from the control group. Anti-EV IgG levels in serum and bile were significantly higher in hamsters vaccinated with EVs compared to control hamsters both pre- and post-challenge. In addition, levels of anti-rOv-TSP antibodies in the serum and bile were significantly higher than control hamsters both pre- and post-challenge. Finally, antibodies against rOv-TSP-2 and rOv-TSP-3 blocked uptake of EVs by human primary cholangiocyte in vitro, providing a plausible mechanism by which these vaccines exert partial efficacy and reduce the intensity of O. viverrini infection. Conclusion/Significance Liver fluke EVs and recombinant tetraspanins derived from the EV surface when administered to hamsters induce antibody responses that block EV uptake by target bile duct cells and exert partial efficacy and against O. viverrini challenge. Cholangiocarcinoma (CCA) is a significant public health problem in countries throughout Southeast Asia. In these areas CCA has a strong association with chronic infection with the food-borne liver fluke Opisthorchis viverrini. Current control of the infection relies on chemotherapy and health education, however these approaches are not sustainable in isolation. Hence, there is an urgent need for a vaccine against this neglected tropical disease. A vaccine against O. viverrini would confer anti-cancer protection in similar fashion to the acclaimed vaccine for human papillomavirus and cervical cancer. Toward this goal, secreted extracellular vesicles (EVs) of O. viverrini and recombinant proteins from the surface of EVs were generated and tested as vaccines in a hamster challenge model. Vaccination of hamsters with EVs and recombinant proteins induced production of antibodies in serum and bile, and those antibodies blocked uptake of EVs by primary bile duct cells in vitro. Challenge of vaccinated hamsters with infective stage flukes markedly reduced adult fluke recovery compared to the adjuvant control group. This is the first report of successful vaccination of hamsters with O. viverrini EVs and recombinant vesicle surface proteins, and provides proof-of-concept for development of subunit vaccines for this carcinogenic infection.

Abstract
To combat and eventually eliminate the transmission of the liver fluke Opisthorchis viverrini, an accurate and practical diagnostic test is required. A recently established urine antigen detection test using monoclonal antibody-based enzyme-linked-immunosorbent assay (mAb-ELISA) has shown promise due to its high diagnostic accuracy and the use of urine in place of fecal samples. To further test the utility of this urine assay, we performed a cross sectional study of 1,043 people in 3 opisthorchiasis endemic communities in northeast Thailand by applying urine antigen detection together with copro-antigen detection methods. The quantitative formalin-ethyl acetate concentration technique (FECT) was concurrently performed as a reference method. The prevalence of O. viverrini determined by urine antigen detection correlated well with that by copro-antigen detection and both methods showed 10-15% higher prevalence than FECT. Within the fecal negative cases by FECT, 29% and 43% were positive by urine and copro-antigen detection, respectively. The prevalence and intensity profiles determined by antigen detection and FECT showed similar patterns of increasing trends of infection with age. The concentration of antigen measured in urine showed a positive relationship with the concentration of copro-antigen, both of which were positively correlated with fecal egg counts. The data observed in this study indicate that urine antigen detection had high diagnostic accuracy and was in concordance with copro-antigen detection. Due to the ease and noninvasiveness of sample collection, the urine assay has high potential for clinical diagnosis as well as population screening in the program for the control and elimination of opisthorchiasis.

Abstract
In contrast to northern and northeastern Thailand, central Thailand was believed not to be endemic for Opisthorchis viverrini (OV). Fieldwork conducted in a rural area of central Thailand revealed that the prevalence and incidence were relatively high compared with regional average data. We hypothesized that the behavioural-psycho-social background of the study population might play an important role in the high burden of the infection. As a result, a qualitative study was conducted to highlight potential social determinants of the infection dynamics to gain greater understanding of the risk behaviours and their contexts. A qualitative study using focus group discussion and in-depth interviews was conducted in Na-ngam Village, Chachoengsao Province from 2012-14. Framework analysis was used to explore associations between infection and thematic content. Social influence showed a strong impact on infection dynamics of OV infection. Our results revealed that Koi pla (chopped raw fish salad) remains a popular dish in the community, as the dish itself represents northeastern culture. The cultural norm had been transferred from ancestors to their descendants. Some elders complained that discontinuing the consumption of Koi pla went against old traditions with respect to cultural norms and socialization. In contrast, modern education teaches about hygiene including OV infection risks, and accordingly teenagers and young adults were reported to modify their lifestyles including their eating habits. Children are a potential key to pass knowledge to their parents and school-based education programs can serve as a practical hub for knowledge dissemination. However, health education alone might not lead to behavioural change in other age groups. Therefore, more efforts are needed to support the transformation.

Abstract
Infection with the food-borne liver fluke Opisthorchis viverrini is the principal risk factor (IARC Working Group on the Evaluation of Carcinogenic Risks to Humans, 2012) for cholangiocarcinoma (CCA) in the Lower Mekong River Basin countries including Thailand, Lao PDR, Vietnam and Cambodia. We exploited this link to explore the role of the secreted growth factor termed liver fluke granulin (Ov-GRN-1) in pre-malignant lesions by undertaking programmed CRISPR/Cas9 knockout of the Ov-GRN-1 gene from the liver fluke genome. Deep sequencing of amplicon libraries from genomic DNA of gene-edited parasites revealed Cas9-catalyzed mutations within Ov-GRN-1. Gene editing resulted in rapid depletion of Ov-GRN-1 transcripts and the encoded Ov-GRN-1 protein. Gene-edited parasites colonized the biliary tract of hamsters and developed into adult flukes, but the infection resulted in reduced pathology as evidenced by attenuated biliary hyperplasia and fibrosis. Not only does this report pioneer programmed gene-editing in parasitic flatworms, but also the striking, clinically-relevant pathophysiological phenotype confirms the role for Ov-GRN-1 in virulence morbidity during opisthorchiasis.

Abstract
The secreted growth factor granulin (GRN) is upregulated during diverse epithelial cancers. GRN stimulates cell growth and development while inhibiting apoptosis. Orthologues of vertebrate granulins evolved in other animals including the liver fluke Opisthorchis viverrini. Curiously, liver fluke granulin, termed Ov-GRN-1 promotes cholangiocarcinogenesis during chronic opisthorchiasis but, by contrast, limited information is available concerning mammalian GRN during liver fluke infection-induced cholangiocarcinoma (CCA). Here we investigated the expression of mammalian granulin in the O. viverrini-associated a hamster model of opisthorchiasis and liver fluke infection-induced CCA. Male Syrian golden hamsters were assigned to one of four treatment groups, each group included 30 hamsters: 1) normal (control), 2) infected with O. viverrini (OV); 3) exposed to N-dimethylnitrosamine in drinking water (DMN); and 4) infected with O. viverrini and exposed to DMN (OVDMN). Immunohistochemistry using an anti-granulin specific probe for mammalian granulin was undertaken to monitor expression and location in hepatobiliary tissues of the hamsters. In parallel, cognate studies of transcription of mRNA and protein. Histopathological examination revealed development of proliferative lesions from the onset and eruption of CCA onwards, an outcome that was most prominent in the OVDMN hamsters. Proliferating cell nuclear antigen (PCNA) index rose continuously from initiation of infection and increased with lesion progression in OV, DMN and markedly in OVDMN hamsters. Expression of GRN in biliary was elevated in biliary epithelial cells in CCA lesions in hamsters in the DMN and OVDMN groups. Expression of GRN as assayed by western blot and RT-PCR reflected the same trend as seen with PCNA. Together the histopathogical and molecular assay based findings revealed marked expression of granulin during cholangiocarcinoma in these hamsters, and highlighted the prospect that granulin represents a potential prognostic marker for cholangiocarcinoma.

Abstract
The carcinogenic liver fluke, Opisthorchis viverrini, is a serious health problem in Southeast Asia where infection is associated with cholangiocarcinoma, a major cause of death in Thailand. This cross-sectional study aimed to screen for O. viverrini infection among a Thai rural population of 560 individuals from Nakhon Ratchasima, Khonkaen, and Chaiyaphum provinces with a verbal screening test with a mobile application (OvApp). Faecal samples were also processed with a mini-parasep sf parasite faecal concentrator. The infection rate of O. viverrini was found to be 2.86%. The majority of infections were detected in males aged 41–50, with primary school being their highest education level, and who were engaged in agricultural occupations. In screening for O. viverrini infection, the OvApp had a high sensitivity (87.5%), specificity (94.6%), negative predictive value (98.9%), and accuracy (98.6%). The positive predictive value was 70.0% for the OvApp. The observed agreement was substantial for this application (k-value = 0.64) indicated that it is a potentially useful tool for decreasing the cost of large-scale O. viverrini screening.

Abstract
Complications arising from infection with the carcinogenic liver fluke Opisthorchis viverrini cause substantial morbidity and mortality in Thailand and adjacent lower Mekong countries. In parallel, the incidence rate of diabetes mellitus (DM) is increasing in this same region, and indeed worldwide. Many residents in opisthorchiasis-endemic regions also exhibit DM, but the hepatobiliary disease arising during the co-occurrence of these two conditions remains to be characterized. Here, the histopathological profile during co-occurrence of opisthorchiasis and DM was investigated in a rodent model of human opisthorchiasis in which diabetes was induced with streptozotocin. The effects of excretory/secretory products from the liver fluke, O. viverrini (OVES) on hepatocyte and cholangiocyte responses during hyperglycemic conditions also were monitored. Both the liver fluke-infected hamsters (OV group) and hamsters with DM lost weight compared to control hamsters. Weight loss was even more marked in the hamsters with both opisthorchiasis and DM (OD group). Hypertrophy of hepatocytes, altered biliary canaliculi, and biliary hyperplasia were more prominent in the OD group, compared with OV and DM groups. Profound oxidative DNA damage, evidenced by 8-oxo-2'-deoxyguanosine, proliferating cell nuclear antigen, and periductal fibrosis characterized the OD compared to OV and DM hamsters. Upregulation of expression of cytokines in response to infection and impairment of the pathway for insulin receptor substrate (IRS)/phosphatidylinositol-3-kinases (PI3K)/protein kinase B (AKT) signaling attended these changes. In vitro, OVES and glucose provoked time- and dose-dependent effects on the proliferation of both hepatocytes and cholangiocytes. In overview, the co-occurrence of opisthorchiasis and diabetes exacerbated pathophysiological damage to the hepatobiliary tract. We speculate that opisthorchiasis and diabetes together aggravate hepatobiliary pathogenesis through an IRS/PI3K/AKT-independent pathway.

Abstract
A 12-year-old, female, domestic cat (Felis catus) presented with dehydration, emaciation, anorexia, and lethargy. The cat was unresponsive to medical treatment and euthanized; the carcass was submitted for pathological diagnosis. Necropsy revealed icteric mucous membranes. The liver was enlarged, with multinodular, cystic, white masses, 0.5-4.0 cm in diameter, scattered throughout. Microscopically, the biliary epithelium presented with a proliferation of multifocal cystic masses, occasionally with periodic acid-Schiff-positive fluid within the cysts. Simple cuboidal epithelial cells showed small, round to oval, vesicular nuclei and rare mitotic figures. There were also multifocal trematode-like parasites situated within the biliary tracts. Immunohistochemistry of the cystic masses was positive for pan-cytokeratin and proliferating cell nuclear antigen, while negative for vimentin. Molecular analysis and gene sequencing of the parasite indicated that it was Opisthorchis viverrini. Based on the pathological findings and molecular analysis, the cat was diagnosed with biliary cystadenoma related to O. viverrini infection. This report described an unusual case of O. viverrini infection associated with biliary tumor in a cat, and raises the possibility of domestic cats as a reservoir host of the human liver fluke.

Abstract
BACKGROUND An opisthorchiid liver fluke was recently reported from ducks (Anas platyrhynchos) in Binh Dinh Province of Central Vietnam, and referred to as "Opisthorchis viverrini-like". This species uses common cyprinoid fishes as second intermediate hosts as does Opisthorchis viverrini, with which it is sympatric in this province. In this study, we refer to the liver fluke from ducks as "Opisthorchis sp. BD2013", and provide new sequence data from the mitochondrial (mt) genome and the nuclear ribosomal transcription unit. A phylogenetic analysis was conducted to clarify the basal taxonomic position of this species from ducks within the genus Opisthorchis (Digenea: Opisthorchiidae). METHODS Adults and eggs of liver flukes were collected from ducks, metacercariae from fishes (Puntius brevis, Rasbora aurotaenia, Esomus metallicus) and cercariae from snails (Bithynia funiculata) in different localities in Binh Dinh Province. From four developmental life stage samples (adults, eggs, metacercariae and cercariae), the complete cytochrome b (cob), nicotinamide dehydrogenase subunit 1 (nad1) and cytochrome c oxidase subunit 1 (cox1) genes, and near-complete 18S and partial 28S ribosomal DNA (rDNA) sequences were obtained by PCR-coupled sequencing. The alignments of nucleotide sequences of concatenated cob + nad1 + cox1, and of concatenated 18S + 28S were separately subjected to phylogenetic analyses. Homologous sequences from other trematode species were included in each alignment. RESULTS Phylogenetic trees were inferred from concatenated (cob + nad1 + cox1) nucleotide sequences and combined 18S + 28S nucleotide sequences of five Opisthorchis sp. BD2013 samples and additional reference taxa. Both trees demonstrated the anticipated clustering of taxa within the superfamily Opisthorchioidea, the paraphyly of the genus Opisthorchis and the sister-species relationship of Opisthorchis sp. BD2013 with O. viverrini. CONCLUSIONS While it is likely that Opisthorchis sp. BD2013 is distinct from O. viverrini, it is clearly a sister taxon of O. viverrini within the limited number of Opisthorchis species for which appropriate sequence data are available. The new sequences provided here will assist the diagnosis and the taxonomic clarification of the opisthorchiid species.

Abstract
BACKGROUND Opisthorchis viverrini infection is a major public health problem in northern and northeastern Thailand. The chronic infection of O. viverrini is related to cholangiocarcinoma which causes high mortality in endemic areas. Therefore, the diagnosis, treatment, control and prevention of O. viverrini infection are necessary. The morphology of the egg is very similar to that of other species of human liver flukes (Opisthorchis felineus and Clonorchis sinensis) as well as that of small intestinal flukes in the family Heterophyidae. Thus, molecular characterization is crucially required to discriminate species of Opisthorchis-like eggs in fecal examination. METHODOLOGY/PRINCIPAL FINDINGS We aimed to determine the prevalence of O. viverrini infection among villagers living in Sanamchaikate District, Chachoengsao Province, in central Thailand, where O. viverrini infection has previously been reported. A total of 2,609 fecal samples were examined for Opisthorchis-like eggs using microscopic examination. PCR-RFLP analysis of the ITS2 region was used to discriminate Opisthorchis-like eggs. The genetic structure of O. viverrini infection was demonstrated using nucleotide sequencing of cytochrome c oxidase subunit I (cox1) and NADH dehydrogenase subunit 1 (nad1). Testing of evolutionary neutrality of the cox1 and nad1 sequences of O. viverrini was performed using Tajima's D tests and Fu's Fs tests. Moreover, the haplotype networks and phylogenetic trees were constructed to study the relationships of O. viverrini isolated from different endemic areas. A high prevalence of O. viverrini infection is still observed in a rural community of Chachoengsao Province, central Thailand. The overall prevalence of Opisthorchis-like eggs using microscopic examination was 16.8%. PCR-RFLP profiles showed the predominant infection of O. viverrini (9.6%) including very low infections of other small intestinal flukes, Haplorchis taichui (0.08%) and Euparyphium albuferensis (0.08%). The genetic structure of O. viverrini populations in central Thailand was also described and revealed a non-significant difference in genetic diversity. In addition, the genetic background of the O. viverrini populations was closely related to the isolate from Lao PDR. CONCLUSIONS/SIGNIFICANCE Our study highlighted the prevalence of O. viverrini infection in central Thailand indicating that control programs and health education regarding opisthorchiasis is still required in this endemic area. Additionally, the study demonstrated the genetic structure of O. viverrini, in central Thailand which could provide information on the molecular epidemiology of this parasite.

Abstract
BACKGROUND Opisthorchiasis is a parasitic infection caused by the liver flukes of the Opisthorchiidae family. Both experimental and epidemiological data strongly support a role of these parasites in the etiology of the hepatobiliary pathologies and an increased risk of intrahepatic cholangiocarcinoma. Understanding a functional link between the infection and hepatobiliary pathologies requires a detailed description a host-parasite interaction on different levels of biological regulation including the metabolic response on the infection. The last one, however, remains practically undocumented. Here we are describing a host response on Opisthorchiidae infection using a metabolomics approach and present the first exploratory metabolomics study of an experimental model of O. felineus infection. METHODOLOGY AND PRINCIPAL FINDINGS We conducted a Nuclear Magnetic Resonance (NMR) based longitudinal metabolomics study involving a cohort of 30 animals with two degrees of infection and a control group. An exploratory analysis shows that the most noticeable trend (30% of total variance) in the data was related to the gender differences. Therefore further analysis was done of each gender group separately applying a multivariate extension of the ANOVA-ASCA (ANOVA simultaneous component analysis). We show that in the males the infection specific time trends are present in the main component (43.5% variance), while in the females it is presented only in the second component and covers 24% of the variance. We have selected and annotated 24 metabolites associated with the observed effects and provided a physiological interpretation of the findings. CONCLUSIONS The first exploratory metabolomics study an experimental model of O. felineus infection is presented. Our data show that at early stage of infection a response of an organism unfolds in a gender specific manner. Also main physiological mechanisms affected appear rather nonspecific (a status of the metabolic stress) the data provides a set of the hypothesis for a search of the more specific metabolic markers of the Opisthorchiidae infection.

Abstract
Infection with the fish borne liver fluke Opisthorchis felineus is common in the Eastern Europe (Ukraine, European part of Russia), Northern Asia (Siberia) and Central Asia (Northern Kazakhstan). Better understanding of the molecular pathogenesis of the biliary tract and liver during chronic opisthorchiasis can be expected to improve protection against and management of complications of this disease. We hypothesize that infection with O. felineus associates with formation of methylglyoxal and carbonyl stress in the liver and hence here we investigated the glyoxalase system and the receptor for advanced glycated end products (RAGE) in the liver of hamsters infected with this liver fluke. Expression of mRNA encoding glyoxalase 1 decreased at 8weeks of the infection and catalytic activity as well decreased at 8 and 12weeks after infection, and the expression of the glyoxalase 2 decreased until 36week post-infection, which associated with the decreasing activity of the enzyme at 8 and 12weeks post-infection. Glutathione levels in infected livers had decreased at week 8, whereas up-regulation of RAGE at mRNA levels was seen for the extended duration of the experimental infection of the hamsters. This outcome supported the notion of hepatic dicarbonyl stress during chronic opisthorchiasis. The inhibition of the glyoxalase system and accumulation of methylglyoxal at the early stages of the infection may underpin development of insulin resistance during opisthorchiasis.

Abstract
Diagnosis of Opisthorchis viverrini infection by conventional stool examination is increasingly difficult due to the low intensity of the infection after several rounds of control programmes in endemic regions as well as coinfections with intestinal flukes. Therefore sensitive and specific diagnostic test is needed. In this study, a coproantigen sandwich ELISA using recombinant O. viverrini cathepsin F (rOv-CF) was developed. This sandwich ELISA employing chicken IgY raised against rOv-CF in combination with rabbit IgG antibody to the somatic O. viverrini antigens showed a lower detection limit (LLD) of 70ng native O. viverrini somatic antigens by spiking the parasite antigens into control feces. When applied to the diagnosis, the IgY-based sandwich ELISA exhibited sensitivity and specificity of 93.3% and 76.7%, respectively, in an investigation of 90 human cases positive or negative for opisthorchiasis. The positive predictive value (PPV) and negative predictive value (NPV) for this coproantigen detection were 66.7% and 95.2%, respectively. This IgY-based sandwich ELISA using parasite cathepsin F detection shows a promising immunodiagnostic alternative for human opisthorchiasis in endemic regions.

Abstract
Opisthorchis viverrini is endemic in the South East Asian region, especially in Cambodia, Lao People's Democratic Republic, Vietnam and Thailand, but there have been no previous records from Myanmar. During stool surveys of rural populations in three regions of Lower Myanmar, Opisthorchis-like eggs were found in 34 out of 364 (9.3%) participants by stool microscopy after using the modified formalin-ether concentration technique. DNA was extracted from these positive stool samples and a portion of the mitochondrial cytochrome c oxidase subunit I (cox1) gene was amplified using the polymerase chain reaction and then sequenced. DNA sequences, successfully obtained from 18 of 34 positive samples (Bago Region, n = 13; Mon State, n = 3; Yangon Region, n = 2), confirmed that the eggs were of O. viverrini. Sequences showed 99.7% identity with O. viverrini mitochondrial cox1 (GenBank accession no. JF739555) but 95%, 88.7%, 82.6% and 81.4% identities with those of Opisthorchis lobatus from Lao People's Democratic Republic (GenBank accession nos. HQ328539-HQ328541), Metorchis orientalis from China (KT239342), Clonorchis sinensis from China (JF729303) and Opisthorchis felineus from Russia (EU921260), respectively. When alignement with other Opisthorchiidae trematodes, 81% similarity with Metorchis bilis from Czech Republic (GenBank accession nos. KT740966, KT740969, KT740970) and Slovakia (GenBank accession nos. KT740971-KT740973), 84.6% similarity with Metorchis xanthosomus from Czech Republic (GenBank accession no. KT740974), 78.6% similarity with M. xanthosomus from Poland (GenBank accession no. KT740968) and 82.2% similarity with Euamphimerus pancreaticus from Czech Republic (GenBank accession no. KT740975) were revealed. This study demonstrated, for the first time, O. viverrini from rural people in Myanmar using molecular methods and is an urgent call for surveillance and control activities against opisthorchiasis in Myanmar.

Abstract
Parts of Southeast Asia have the highest incidence of intrahepatic cholangiocarcinoma (CCA) in the world because of infection by the liver fluke Opisthorchis viverrini (Ov). Ov-associated CCA is the culmination of chronic Ov-infection, with the persistent production of the growth factors and cytokines associated with persistent inflammation, which can endure for years in Ov-infected individuals prior to transitioning to CCA. Isobaric labeling and tandem mass spectrometry of liver tissue from a hamster model of CCA was used to compare protein expression profiles from inflammed tissue (Ovinfected but not cancerous) versus cancerous tissue (Ov-induced CCA). Immunohistochemistry and immunoblotting were used to verify dysregulated proteins in the animal model and in human tissue. We identified 154 dysregulated proteins that marked the transition from Ov-infection to Ov-induced CCA, i.e. proteins dysregulated during carcinogenesis but not Ov-infection. The verification of dysregulated proteins in resected liver tissue from humans with Ov-associated CCA showed the numerous parallels in protein dysregulation between human and animal models of Ov-induced CCA. To identify potential circulating markers for CCA, dysregulated proteins were compared with proteins isolated from exosomes secreted by a human CCA cell line (KKU055) and 27 proteins were identified as dysregulated in CCA and present in exosomes. These data form the basis of potential diagnostic biomarkers for human Ov-associated CCA. The profile of protein dysregulation observed during chronic Ovinfection and then in Ov-induced CCA provides insight into the etiology of an infection-induced inflammation-related cancer.

Abstract
BACKGROUND Foodborne trematodiasis (FBT) is a significant global health problem, with the liver flukes Opisthorchis viverrini, O. felineus, and Clonorchis sinensis contributing to half of the global burden of FBT. North-eastern Thailand where O. viverrini is endemic and un-cooked fish dishes remain an integral part of the food culture has the highest reported incidence of opisthorchiasis, including associated cholangiocarcinoma. Both food sharing and eating practices are potentially important factors in FTB, suggesting an important role for the social ecology of disease transmission in these rural communities. METHODS Two rural Thai-Lao villages that were part of a 12-village project in Northeastern Thailand were selected for detailed investigation of O. viverrini infection risk associated with sharing of raw fish dishes among households. The project included screening individuals for infection and cholangiocarcinoma, a household questionnaire, and offering treatment options for positive individuals. Social network mapping was used to construct raw fish dish-sharing networks and create a proxy variable capturing variability in the degree of food sharing (DFS), measured as the number of different households with which each household shared fish dishes. Measures of associations between DFS, O. viverrini infection, the frequency of raw fish consumption, and the number of raw fish dishes consumed were generated using binary logistic regression, proportional odds ordinal logistic regression, and Poisson regression. RESULTS The results showed that the probability that a household has members infected with O. viverrini increased by ~7% (P < 0.01) for each additional household included in its network. Moreover, the frequency and number of types of raw fish dishes consumed increased significantly as the DFS increased. Of the two villages, that with the highest infection prevalence (48% versus 34.6%) had significantly higher social connectivity overall (P < 0.001). CONCLUSIONS Our findings suggest that the social ecology of human settlements may be key to understanding the transmission dynamics of some FBT. In the case of O. viverrini in Thai-Lao communities, for which food sharing is a traditional practice supporting social cohesion, food sharing network mapping should be incorporated into community-based interventions. These should encourage fish dish preparation methods that minimize infection risk by targeting households with high DFS values.

Abstract
Opisthorchiasis is the commonest liver disease caused by Opisthorchis viverrini in Thailand, Lao People's Democratic Republic (PDR) and Cambodia, which will be a major cause of future human cholangiocarcinoma in these regions. In this short review, we describe the epidemic aspects of this parasite infection and the outline of results of our recent surveys of the fluke in humans and its intermediate hosts in Vientiane Capital, where information on the opisthorchiasis epidemic is insufficient. We examined the stool from a total of 296 persons living in the Phailom village (population, 1545, 1999) from 2011 to 2012. As a result, the intestinal parasitism rate was very high from 54 to 59%. Among intestinal infections, O. viverrini infection was observed at highest rates from 51 to 53%. On the other hand, the rate of infection by nematodes was very low. We also conducted intermediate-host investigations in the river and damp areas at 3 villages in the Vientiane capital and 2 villages in Vientiane Province in 2012. As shown by these results, no Opisthorchis species was detected in 147 samples of the host genus Bythinia. However, metacercariae were detected in 3 samples of Cyclocheilichthys sp. and in a Hampala sp. in 303 cyprinid fishes collected from the Haikham village area of Vientiane Capital.

Abstract
The importance of the development of the effective rehabilitative measures for the patients suffering from chronic cholecystitis with concomitant gallbladder dysfunction and opisthorchiasis is beyond question. The adequate methods for the rehabilitation of the patients after an intensive de-worming remain to be developed. It is known that de-worming is not infrequently followed by the immediate amplification of the manifestations of the stagnation of bile in the gallbladder that become even more pronounced than before the de-worming procedure. With the purpose of improving the effectiveness of the spa and health resort-based rehabilitation and prevention of the complications, it is recommended to make use of the modern therapeutic physical factors to be prescribed taking into consideration the characteristics of the biological rhythms in the functional activity of the biliary system in the individual patients. The most effective rehabilitation methods for the treatment of the pathology in question include the application of the therapeutic physical factors known to produce the beneficial effect on the functional state of the biliary system and exert the normalizing influence on the structure of the biological rhythms of the functional activity of various organs and systems. We used a range of approaches for the treatment of 123 patients with chronic cholecystitis and concomitant gallbladder dysfunction plus opisthorchiasis including extremely high-frequency electromagnetic irradiation (EHF therapy) in the combination with the oral intake of the choleretic herbal remedies followed by the transverse galvanization of the epigastric region with due regard for the phase of the rhythm of the functional activity of the gallbladder. The results of such treatment gave evidence of the positive dynamics of all the studied indicators of the functional activity of the biliary system and the organism as a whole which suggests the highest therapeutic effect (87.9%) of the proposed treatment that was maintained during 6 to 12 months.

Abstract
BACKGROUND Helminth infections have proven recalcitrant to control by chemotherapy in many parts of Southeast Asia and indeed farther afield. This study isolates and examines the influence of different aspects of the physical and social environment, and uneven intervention effort contributing to the pathogenic landscape of human Opisthorchis viverrini infections. METHODOLOGY A cross-sectional survey, involving 632 participants, was conducted in four villages in northeast Thailand to examine the impact on prevalence and parasite burden of the reservoir dam environment, socio-economic, demographic, and behavioral factors, and health center intervention efforts. Formalin-ether concentration technique was used for diagnoses, and multivariate models were used for analyses. PRINCIPAL FINDINGS The importance attributed to O. viverrini infections varied among health centers in the four study villages. Villages where O. viverrini infections were not prioritized by the health centers as the healthcare focus were at a higher risk of infection (prevalence) with odds ratio (risk factor) of 5.73 (3.32-10.27) and p-value < 0.01. Priority of healthcare focus, however, did not appear to influence behavior, as the consumption of raw fish, the main source of O. viverrini infections in the study area, was 11.4% higher in villages that prioritized O. viverrini infections than those that did not (p-value = 0.01). Landscape variation, notably proximity to reservoir, affects vulnerability of local population to infection. Infection intensity was higher in population located closer to the reservoir with risk ratio of 2.09 (1.12-4.02) and p-value < 0.01. Patterns of infection intensities among humans were found to match fish infection intensity, where higher infection intensities were associated with fish obtained from the reservoir waterbody type (p-value = 0.023). CONCLUSIONS/SIGNIFICANCE This study demonstrated the importance of environmental influence and healthcare focus as risk factors of infections in addition to the socio-economic, demographic, and behavioral factors commonly explored in existing studies. The reservoir was identified as a crucial source to target for opisthorchiasis intervention efforts and the need to consider infection intensity in disease control efforts was highlighted. The holistic approach in this study, which underscores the close relationship between the environment, animals, and humans in development of human infections or diseases, is an important contribution to the framework of One Health approach, where consideration of helminth diseases has largely been overlooked.

Abstract
BACKGROUND Opisthorchis viverrini (Ov) is a complex-life-cycle trematode affecting 10 million people in SEA (Southeast Asia). Human infection occurs when infected cyprinid fish are consumed raw or undercooked. Ov requires three hosts and presents two free-living parasitic stages. As a consequence Ov transmission and infection in intermediate and human hosts are strongly mediated by environmental factors and understanding how environmental variability influences intermediate host abundance is critical. The objectives of this study were 1) to document water parameters, intermediate hosts abundance and infection spatio-temporal variation, 2) to assess their causal relationships and identify windows of transmission risk. METHODOLOGY/PRINCIPAL FINDINGS Fish and snails were collected monthly for one year at 12 sites in Lawa Lake, an Ov-endemic region of Khon Kaen Province in Northeast Thailand. Physicochemical water parameters [pH, temperature (Tp), dissolved oxygen (DO), Salinity, electrical conductivity (EC), total dissolved solid (TDS), nitrite nitrogen (NO2-N), lead (Pb), total coliform bacteria (TCB) and fecal coliform bacteria (FCB)] were measured. Multivariate analyses, linear models and kriging were used to characterize water parameter variation and its influence on host abundance and infection prevalence. We found that sampling sites could be grouped in three clusters and discriminated along a nitrogen-salinity gradient where higher levels in the lake's southern region predicted higher Bithynia relative abundance (P<0.05) and lower snail and fish species diversity (P<0.05). Highest Bithynia abundance occurred during rainy season (P<0.001), independently of site influence. Cyprinids were the most abundant fish family and higher cyprinid relative abundance was found in areas with higher Bithynia relative abundance (P<0.05). Ov infection in snails was anecdotal while Ov infection in fish was higher in the southern region (P<0.001) at sites showing high FCB. CONCLUSIONS/SIGNIFICANCE Our results indicate that water contamination and waterways configuration can influence freshwater communities' assemblages possibly creating ideal conditions for sustained transmission. Sustainable control may require a better appreciation of the system's ecology with wise governance and development planning particularly in the current context of SEA agricultural intensification and landscape modification.

Abstract
BACKGROUND Opisthorchis viverrini is endemic in the Lower Mekong Basin, including Thailand, Lao People’s Democratic Republic, Cambodia, and central Vietnam. This figure indicates that it is a serious public health problem in Thailand, particularly in northeastern and northern region. OBJECTIVE To survey the nutritional status among schoolchildren including the association between nutritional status and related O. viverrini infection that is reported in their living areas. MATERIAL AND METHOD A cross-sectional survey of nutritional status among schoolchildren was conducted in the rural communities of Surin province, Thailand, between September 2013 and July 2014. Nutritional evaluations, Socio-economic, and family information were collected through questionnaires. Four hundred sixty two children aged between 6 to 14 years were enrolled. Pearson correlation test and multiple logistic regression were used in this study. RESULTS Most respondents who answered the questionnaire were mother (37.23%), and followed by children (34.41), female (51.73%), and age rank older than 9 to 12 years old (41.99%). Schoolchildren were evaluated for weigh for age, which resulted in normal weight (60.82%), wasting (8.01%), underweight (7.58%), obesity (2.38%), and overweight (1.95%). Height for age was divided into normal height (60.17%), stunting (0.74%), slightly short (4.76%), tall (3.46%), and slightly tall (2.6%). Weight for height was divided into appropriate (54.11%), thin (10.82%), slightly thin (8.02%), obesity (2.38%), and morbid obesity (1.73%). Children were not infected with O. viverrini in this study even if 15.8% of them consumed undercooked particularly cyprinoid fish. Children with slightly underweight was statistically significant associated with O. viverrini infection (Adjust R square = 0.445, p<0.05). The equation for prediction of liver fluke infection among schoolchildren who had slightly underweight is Y = -0.508 + 0.517 X(12) and Z = 0.694 X(12). CONCLUSION The present study indicates that stunting, underweight and wasting children were found in high infectious areas of O. viverrini. Slightly underweight was associated with infection. Therefore, implementation of nutrient in this group is urgently required. Furthermore, health education for children and relative family should be encouraged for further campaign in this province.

Abstract
BACKGROUND Opisthorchis viverrini is still a serious problem in rural areas of Thailand particularly Northeastern and Northern region. Active surveillance is required to determine the update data for further prevention and control planning. OBJECTIVE To determine the population at risk and analyze the risk areas for O. viverrini in rural communities of Nakhon Ratchasima province, Thailand. MATERIAL AND METHOD A cross-sectional survey was conducted between October 2015 and March 2016 at Kang Sanam Nang district, Nakhon Ratchasima province, Thailand. The population at risk for O. viverrini was screened by SUT-OV-001 with Cronbach’ alpha coefficient, 0.724. O. viverrini infection was examined by using Kato thick smear. The risk areas were analyzed by using geographic information system. RESULTS Three hundred ninety seven people were recruited for this study. The majorities were female (53.15%), age group 41 to 50 years old (35.01%), educated with primary school (59.45%), agriculture (85.64%), and of income of 2,000 baht (47.36%). The majorities of them were high-risk (49.62%), followed by moderate risk (36.02%), and low-risk (7.3%). Risk areas were classified as very-high-risk areas, found in Beng Samrong (11.44 km(2)), followed by Keang Sanam Nang (5.21 km(2)). High-risk areas were found in Bueng Phalai sub-district (70.16 km(2)), followed by Bueng Samrong (30.45 km(2)), and Non Samran (27.33 km(2)). O. viverrini infection was 3.02%, and distributed in the moderate risk areas (four cases), high-risk areas (three cases), low-risk areas (three cases), and very-high-risk areas (two cases). CONCLUSION The present study indicates the population at risk for O. viverrini and risk areas in the rural communities by using SUT-OV-001 and GIS. These tools are useful to display the risk areas for further prevention and control planning and monitor.

Abstract
BACKGROUND Treatment of the liver fluke infection Opisthorchis viverrini relies exclusively on praziquantel. Tribendimidine could be an alternative treatment option. We aimed to assess the efficacy and safety of ascending single, oral doses of tribendimidine in patients with O viverrini infection. METHODS We did two randomised, parallel-group, single-blind, dose-ranging, phase 2 trials in children (aged 8-14 years) and adults and adolescents (≥15 years) in three O viverrini endemic villages in Champasack province, southern Laos. Patients with O viverrini infection were randomly assigned, via a computer-generated central block-randomisation procedure, with block sizes of three (study 1) and four, eight, and 12 (study 2), to receive oral tribendimidine at doses of 200 mg, 400 mg, or 600 mg in a 1:1:1 ratio (adults and adolescents in study 1); 25 mg, 50 mg, 100 mg, or 200 mg (four 50 mg tablets) in a 1:1:1:1 ratio (adults and adolescents in study 2); or 100 mg, 200 mg, or 400 mg in a 1:1:1 ratio (children in study 1). One non-randomised group of children received tribendimidine 50 mg (study 2). Participants, investigators, and laboratory technicians doing the diagnostic assessments were masked to group assignment, but the investigator administering treatment could have recognised the treatment group based on the number of tablets. The primary objective was to estimate the dose-response relation in terms of cure rate and egg reduction rate. We did available-case analysis of all patients with primary endpoint data. We predicted dose-response associations with Emax models. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN96948551. FINDINGS Between Oct 25, 2012, and Nov 5, 2013, 318 adolescents and adults were randomly assigned to seven tribendimidine dose groups: 200 mg (n=51), 400 mg (n=49), or 600 mg (n=47) in study 1, and 25 mg (n=39), 50 mg (n=47), 100 mg (n=44), or 200 mg (four 50 mg tablets; n=41) in study 2. 128 children were randomly assigned to receive tribendimidine 100 mg (n=44), 200 mg (n=40), or 400 mg (n=44) in study 1; 39 children were enrolled and received tribendimidine 50 mg in study 2. In adolescents and adults, the number of patients cured increased with increasing tribendimidine doses up to 100 mg: ten of 39 patients (25·6%, 95% CI 13·0-42·1) were cured in the 25 mg group, 20 of 47 patients (42·6%, 28·3-57·8) were cured in the 50 mg group, and 34 of 44 patients (77·3%, 62·2-88·5) were cured in the 100 mg group; geometric mean egg reduction rates were 86·9% (95% CI 74·8-93·4), 95·9% (92·7-97·7), and 99·1% (98·2-99·7), respectively. The 200 mg dose resulted in cure in 40 of 47 (83·0%, 69·2-92·5) adolescents and adults given the 200 mg tablet and 25 of 41 (61·0%, 95% CI 44·5-75·8) of those given four 50 mg tablets; the 400 mg dose resulted in cure in 43 of 47 patients (91·5%, 79·6-97·6) and the 600 mg dose resulted in cure in 36 of 45 patients (80·0%, 65·4-90·4). Corresponding egg reduction rates were 99·8% (95% CI 99·7-100·0) with one 200 mg tablet, 97·9% (95·9-99·2) with four 50 mg tablets, 99·9% (99·8-100·0) with 400 mg, and 99·8% (99·6-99·9) with 600 mg. The Emax model predicted an egg reduction rate of 99·0% (95% CI 95·7-99·8) at 111 mg in adolescents and adults. 50 mg tribendimidine had moderate efficacy in children, with cure recorded in 16 of 39 patients (41·0%, 95% CI 25·6-57·9). The 100 mg dose resulted in cure in 40 of 44 children (98·9%, 95% CI 78·3-97·5) and an egg reduction rate of 99·7% (95% CI 99·0-100·0), with no increased efficacy at higher doses. The Emax model predicted an egg reduction rate of 99·0% (95% CI 92·2-99·9) at 215 mg. Few adverse events were reported and were mostly mild, with few moderate and no serious events. The most common adverse events 3 h after treatment in adolescents and adults were vertigo (n=35 [11%]), headache (n=9 [3%]), nausea (n=6 [2%]), and fatigue (n=4 [1%]), and in children were headache (n=3 [2%]), vertigo (n=2 [1%]), and fatigue (n=2 [1%]). INTERPRETATION Tribendimidine has excellent efficacy and tolerability at doses of 100 mg and above. Our study included mainly adults and children with low-intensity O viverrini infection; future studies should assess the efficacy of tribendimidine in patients with infections of moderate and high intensity.

Abstract
Background There is increasing interest in the microbiome of the hepatobiliary system. This study investigated the influence of infection with the fish-borne liver fluke, Opisthorchis felineus on the biliary microbiome of residents of the Tomsk region of western Siberia. Methodology/Principal Findings Samples of bile were provided by 56 study participants, half of who were infected with O. felineus, and all of who were diagnosed with gallstone disease. The microbiota of the bile was investigated using high throughput, Illumina-based sequencing targeting the prokaryotic 16S rRNA gene. About 2,797, discrete phylotypes of prokaryotes were detected. At the level of phylum, bile from participants with opisthorchiasis showed greater numbers of Synergistetes, Spirochaetes, Planctomycetes, TM7 and Verrucomicrobia. Numbers of > 20 phylotypes differed in bile of the O. felineus-infected compared to non-infected participants, including presence of species of the genera Mycoplana, Cellulosimicrobium, Microlunatus and Phycicoccus, and the Archaeans genus, Halogeometricum, and increased numbers of Selenomonas, Bacteroides, Rothia, Leptotrichia, Lactobacillus, Treponema and Klebsiella. Conclusions/Significance Overall, infection with the liver fluke O. felineus modified the biliary microbiome, increasing abundance of bacterial and archaeal phylotypes. The microbiota of the alimentary tract and other sites of the body influences human health. Contrary to popular belief, the bile within the liver is not sterile, and may host a microbiome consisting of diverse species of microbes. The spectrum of microbial species and their numbers within the biliary system may be influenced by disease including infection with pathogens such as parasitic worms and with gallstone disease, liver cancer and other ailments. Here we examined the microbes in the bile of patients from western Siberia, Russia who were concurrently infected with a food-borne parasitic worm, the liver fluke Opisthorchis felineus. Infection with this liver fluke is common in western Siberia, as a consequence of dietary preference for undercooked or smoked fresh-water fishes that often carry the larva of the liver fluke. Using high throughput sequencing targeting a conserved bacterial gene and statistical analyses, numerous bacterial species were identified in the bile of the patients. Infection with the liver fluke modified the biliary microbiome, resulting in abundant and diverse species of bacteria and Archaea.

Abstract
Infection with the human liver fluke Opisthorchis viverrini induces cancer of the bile ducts, cholangiocarcinoma (CCA). It was shown previously that O. viverrini-secreted proteins accelerate wound resolution in human cholangiocytes. Recombinant Ov-GRN-1 (O. viverrini-derived gene encoding granulin-like growth factor) induced angiogenesis and accelerated mouse wound healing. Given the striking similarities of wound healing and cancer progression, here we discuss the major implications of this finding for an infection-induced cancer of major public health significance in the developing world.

Abstract
A cross-sectional survey was conducted among 730 participants from 4 rural districts of Nakhon Ratchasima province, Thailand, with a reported high incidence of liver fluke infection. This study was aimed to examine and evaluate the nutritional status in relation to Opisthorchis viverrini infection. Participants were purposive selected from Chum Phuang, Mueang Yang, Bua Yai, and Kaeng Sanam Nang districts. Stool samples were prepared by Kato Katz technique and then assessed by microscopy. Anthropometry was evaluated according to the body mass index from weight and height. Descriptive statistics and Spearman rank correlation coefficients were used to evaluate the association between the nutritional status and O. viverrini infection. Of 1.64% infected with O. viverrini the highest proportions were found in age groups ≥61 and 41-50 years old, Mueang Yang district. The majorities of participants had normal weight (32.2%), followed by class II obesity (28.1%), class I obesity (21.8%), underweight (10.3%), and class III obesity (8.63%). Nutritional status with class II obesity (rS=0.639, <0.01) and class I obesity (rS=0.582, <0.05), had moderately statistical significant correlations with O. viverrini infection. Meanwhile, normal weight (rS=0.437, <0.05) and class III obesity (rS=0.384, <0.05) demonstrated lower statistical significance. These findings raise the possibility that infection with O. viverrini may contribute to fat deposition and thereby have long-term consequences on human health. Further studies are needed to better understand whether O. viverrini contributes directly to fat deposition and possible mechanisms.

Abstract
A quasi-experimental study was conducted to develop a health education modification program based on self-efficacy and motivation regarding liver flukes and cholangiocarcinoma development in Keang Sanam Nang district, Nakhon Ratchasima province, Thailand. A total of 36 individuals were invited to participate in the program and were screened for population at risk of liver fluke infection and cholangiocarcinoma using SUT-OV-001 and SUT-CCA-001. Development of health education modification program regarding liver fluke and cholangiocarcinoma prevention included 3 steps: (1) preparation, (2) health education program, and (3) follow-up and evaluation. The study was implemented for 10 weeks. Pre-and-post-test knowledge was measured with questionnaires, Kuder-Richardson-20: KR-20 = 0.718,and Cronbach's Alpha Coefficient = 0.724 and 0.716 for perception and outcome expectation questionnaires. Paired and independent t-tests were applied for data analysis. The majority of the participants were female (55.6%), aged between ≤50 and 60 years old (36.1%), married (86.1%), education level of primary school (63.9%), agricultural occupation (80.6%), and income <4,000 Baht (44.4%). The results revealed that after the health education program, the experimental group had a mean score of knowledge, perception, and outcome expectation regarding liver fluke and cholangiocarcinoma prevention significantly higher than before participation and in the control group. In conclusion, this successful health education modification program for liver fluke and cholangiocarcinoma, therefore may useful for further work behavior modification in other epidemic areas.

Abstract
Opisthorchiasis is a health problem in rural communities of Thailand, particularly in the northeast and north regions. Therefore, this study aimed to investigate raw fish consuming behavior related to liver fluke infection among the population at risk for opisthorchiasis and cholangiocarcinoma (CCA). A cross-sectional descriptive study was conducted in Meuang Yang district, Nakhon Ratchasima province, northeast Thailand, between June and October 2015. Participants were screened for CCA, and samples who had a high score of CCA risk were purposively selected. A predesigned questionnaire was utilized to collect the data from all participants. X2-test was used for analysis of associations between demographic data and raw fish consumption. The results revealed that participants had past histories of stool examination (33.0%), liver fluke infection (21.0%), praziquantel use (24.0%), raw fish consumption (78.0%), relatives family consuming raw fish (73.0%), and relatives family with CCA (3.0%). Participants consumed several dished related to liver fluke infection, mainly raw fermented fish (13.0%), under smoked catfish (5.00%), raw pickled fish (4.00%), and raw spicy minced fish salad (3.00%). The most common types of cyprinoid fish were Barbodes gonionotus (39%), Hampala dispar (38%), Puntius brevis (37%), Cyclocheilichthys armatus (33%), Puntioplites proctozysron (32%), and Luciosoma bleekeri (30%), respectively. Participants had a low level of knowledge (mean=3.79, SD=0.74), moderate attitude (mean=7.31, SD=7.31) and practice (mean=38.64, SD=6.95) regarding liver fluke prevention and control. Demographic variables like age (>36 years old; X2-test=17.794, p-value=0.001), education (primary school; X2-test=18.952, p-value=0.001), marital status (married; X2-test=12.399, p-value=0.002), and income (<5,000 baht; X2-test=27.757, p-value=0.015) were significantly associated with raw fish consumption. This result indicates that the population had risk consumption for liver fluke infection particularly of various cyprinoid fishes that are 2nd intermediate hosts. Therefore, health education is required to improve their behavior.

Abstract
This study aimed to modify behavior regarding liver fluke and cholangiocarcinoma prevention in Chumphuang district, Nakhon Ratchasima province, Thailand through integrated learning. A total of 180 participants were included through purposive selection of high-risk scores on verbal screening. Participants attended the health education program which applied the health belief model included family based, knowledge station based, academic merit based and community based learning. Data were collected using a questionnaire composed of 4 parts: 1) personal information, 2) knowledge, 3) perceived susceptibility, severity, benefits, and barriers, 4) practice regarding liver fluke and cholangiocarcinoma prevention. The result revealed that the majority were female (79.9%), age ≥60 years old (33.2%), primary school educational level (76.1%), and agricultural occupation (70.1%). The mean scores of knowledge, perception, and practice to liver fluke and cholangiocarcinoma prevention, before participated the integrative learning were low, moderate, and low, respectively. Meanwhile, the mean score of knowledge, perceived susceptibility, severity, benefits, and barriers, and practice regarding liver fluke and cholangiocarcinoma prevention, were higher with statistical significance after participation in the integrated learning. This finding indicates that health education programs may successfully modify health behavior in the rural communities. Therefore they may useful for further work behavior modification in other epidemic areas.

Abstract
BACKGROUND Opisthorchis viverrini (OV) infection generates oxidative stress/free radicals and is considered as a primary cause ofcholangiocarcinoma since it primarily triggers sclerosing cholangitis. OBJECTIVE In this study, the impacts of andrographolide on acute opisthorchaisis in β-naphthoflavone (BNF)-exposed hamsters were investigated. MATERIAL AND METHOD Ethoxyresorufin O-deethylase (EROD) and methoxyresorufin O-demethylase (MROD) activities and Thiobarbituric acid reaction substances (TBARS) assay of andrographolide in acute opisthorchiasis in the BNF-exposed hamsters were assessed. RESULTS The results showed that andrographolide ameliorated the hepatic CYP1A1 and CYP1A2 activities by decreases of the specific enzymatic reactions of EROD and MROD, respectively, in the BNF-exposed hamsters. Moreover, andrographolide lowered the formation of malondialdehyde in the livers and brains of the hamsters. CONCLUSION These observations revealed the promising chemo-protective and antioxidant activities of andrographolide via suppression of the specific EROD and MROD reactions and lipid peroxidation against acute opisthorchiasis in the BNF-exposed hamsters.

Abstract
Opisthorchis viverrini is still a serious problem in Northeastern and Northern Thailand. Active surveillance is required to determine updated data for further prevention and control planning. Therefore, this study aimed to examine the prevalence and risk factors for O. viverrini in three provinces, Northeastern Thailand. A cross- sectional survey was conducted during October 2015 to March 2016 at Kaeng Sanam Nang district of Nakhon Ratchasima province, Waeng Noi district of Khon Kaen province, and Khon Sawan district of Chaiyaphum province, Thailand. Stool samples were examined by using a modified Kato-Katz Thick smear technique. From a total of 978 participants screened, O. viverrini infection was found in 1.74%, the majority opf positive cases being male (6.62%), age group 51-60 years old (4.21%), educated at primary school (8.43%), occupied with agriculture (9.62%),having an income <4,000 baht per month (4.82%), and living in Khon Sawan district (8.43%). Participants had a high knowledge level (42.43%), good attitude level (34.76%), and fair level (38.04%). The present study indicates the O. viverrini infection rate is low, but elderly males with primary school education involved in agriculture are still frequently effected particularly in Khon Sawan district. Therefore, this risk group requires behavior modification and continued monitoring.

Abstract
PURPOSE To discover protein markers in chronic/advanced opisthorchiasis for the early detection of Opisthorchis viverrini (OV)-associated cholangiocarcinoma (CCA). EXPERIMENTAL DESIGN Liver tissues derived from normal hamsters and those with chronic/advanced opisthorchiasis (n = 5 per group) were subjected to 2DE and LC-MS/MS. Candidate protein expression was confirmed in hamster models and human CCA tissue microarray (TMA) using immunohistochemistry and Western blot. RESULT Proteomics analysis detected 14-3-3 eta only in infected hamsters, not in uninfected controls. Immunohistochemistry and Western blot analysis confirmed low expression of 14-3-3 eta in normal hamster livers and demonstrated increased expression through time in infected livers. This protein was also observed in parasite organs, especially during the chronic phase of opisthorchiasis. Moreover, increased expression of 14-3-3 eta, relative to normal hamster livers, was observed during the early stage of CCA induced by OV infection and administration of N-nitrosodimethylamine. Immunohistochemical analysis of human TMA revealed that 14-3-3 eta was highly expressed in CCA (84.23%, 187/222 cases) but was not found in hepatocellular carcinoma or healthy liver tissues. CONCLUSIONS AND CLINICAL RELEVANCE 14-3-3 eta protein has potential as a screening and early diagnostic marker for CCA.

Abstract
Opisthorchis viverrini infection induces chronic inflammation in the bile ducts, leading to periductal fibrosis (PDF), which possibly associates to cholangiocarcinoma (CCA). Patients with CCA have a poor prognosis, which is linked to asymptomatic disease and late diagnosis. Hence, detecting early stage CCA is essential. Secretory miRNAs have been promoted as biomarkers for pathological changes associated with parasitic infections, fibrosis and/or cancer. We aimed to determine levels of miR-192 and miR-21 in the urine of O. viverrini infected, periductal fibrosis (PDF) and CCA groups using qRT-PCR. We found that miR-192 was significantly higher in O. viverrini infected, PDF and also CCA groups (p<0.05) than in healthy controls. By utilizing the Receiver Operation Characteristics (ROC) analysis, miR-192 differentiated patients with opisthorchiasis (the area under the curve; AUC=0.766), PDF subjects (AUC=0.781) and CCA patients (AUC=0.682) from healthy controls. MiR-21 was significantly higher in PDF and CCA groups (p<0.05) than in healthy controls. MiR-21 discriminated PDF subjects (AUC=0.735) and CCA patients (AUC=0.682) from healthy controls. Combined levels of these two miRNAs revealed an increased AUC of 0.812 for separating opisthorchiasis, AUC of 0.815 in discriminating PDF subjects, and AUC of 0.849 in differentiating CCA from healthy controls. Odds ratios (OR) indicated high levels of miR-192/miR-21 as risk predictors for opisthorchiasis, PDF and CCA. Levels of these miRNAs declined significantly for patients following praziquantel treatment. In conclusion, urinary miR-192/miR-21 have potential as risk indicators for opisthorchiasis and PDF-associated CCA in the endemic region.

Abstract
The paper presents an experimental model of gastric cancer in the presence of chronic opisthorchiasis, which has been created to study its possible role in gastric carcinogenesis. The performed investigation has supported the hypothesis that opisthorchiasis plays a promoting role in the development of experimental gastric cancer. A larger number of experimental hamsters receiving the carcinogen methylnitronitrosoguanidine (MNNG) developed earlier gastric tumors in. the presence of chronic opisthorchiasis than the control animals in the experiment.
