JOURNAL OF EXPOSURE SCIENCE & ENVIRONMENTAL EPIDEMIOLOGY 2024:10.1038/s41370-024-00664-z. [PMID: 38654145 DOI: 10.1038/s41370-024-00664-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 03/13/2024] [Accepted: 03/13/2024] [Indexed: 04/25/2024]
Abstract
BACKGROUND Geographical and meteorological factors have been reported to influence the prevalence of echinococcosis, but there's a lack of indicator system and model. OBJECTIVE To provide further insight into the impact of geographical and meteorological factors on AE prevalence and establish a theoretical basis for prevention and control. METHODS Principal component and regression analysis were used to screen and establish a three-level indicator system. Relative weights were examined to determine the impact of each indicator, and five mathematical models were compared to identify the best predictive model for AE epidemic levels. RESULTS By analyzing the data downloaded from the China Meteorological Data Service Center and Geospatial Data Cloud, we established the KCBIS, including 50 basic indicators which could be directly obtained online, 15 characteristic indicators which were linear combination of the basic indicators and showed a linear relationship with AE epidemic, and 8 key indicators which were characteristic indicators with a clearer relationships and fewer mixed effects. The relative weight analysis revealed that monthly precipitation, monthly cold days, the difference between negative and positive temperature anomalies, basic air temperature conditions, altitude, the difference between positive and negative atmospheric pressure anomalies, monthy extremely hot days, and monthly fresh breeze days were correlated with the natural logarithm of AE prevalence, with sequential decreases in their relative weights. The multinomial logistic regression model was the best predictor at epidemic levels 1, 3, 5, and 6, whereas the CART model was the best predictor at epidemic levels 2, 4, and 5.

Human Cystic Echinococcosis in Lebanon: A Retrospective Study and Molecular Epidemiology. Acta Parasitol 2022; 67:186-195. [PMID: 34264443 PMCID: PMC8938340 DOI: 10.1007/s11686-021-00453-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Accepted: 07/06/2021] [Indexed: 11/26/2022]
Abstract
Purpose Human cystic echinococcosis (CE) is a zoonotic parasitic disease that constitutes a public health challenge and a socio-economic burden in endemic areas worldwide. No specific surveillance system of CE infections in humans exists in Lebanon. The incidence and trends over time have not been documented. The current study aimed to assess the demographic and epidemiologic features of human CE surgical cases over a 14-year period in the five main regions of Lebanon. Methods From 2005 to 2018, a total of 894 surgically confirmed cases of hydatidosis were recorded from five anatomy and pathology laboratories. Results The mean annual surgical incidence was 1.23/100,000 inhabitants. Over the span of these years, the incidence increased from 0.53 to 1.94 cases/100,000 inhabitants in 2005 and 2018, respectively. CE is present in Lebanon with an uneven distribution from one region to the other with higher prevalence in Bekaa (29.0%), a rural area where sheep raising is widespread. Human CE cases were more common in females (60.1%) than in males (39.9%) and a high burden of infection was reported for the age group of 30–39 years. Besides, 66.7% of the cases expressed only liver complications whereas, 20.5% showed predilection towards lungs. The 7.8% of cases presented cysts in other organs, and 1.3% showed multiple localizations. Additionally, predominant involvement of Echinococcus granulosus sensu stricto was recorded in human infections. Comparison of Echinococcus granulosus s.s. populations from different Mediterranean countries also revealed high gene flow among this region and sharing of alleles. Conclusion The current study is a step forward to fill the gap of knowledge for the hydatidosis in Lebanon where the lack of epidemiological data and control measures have resulted in higher incidence of human CE.

Comparison of the multi-epitope recombinant antigen DIPOL and hydatid fluid for the diagnosis of patients with cystic echinococcosis. Acta Trop 2022; 225:106208. [PMID: 34687646 DOI: 10.1016/j.actatropica.2021.106208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 09/21/2021] [Accepted: 10/13/2021] [Indexed: 11/01/2022]
Abstract
The use of serological tests containing multiple immunodominant antigens rather than single antigens have the potential to improve the diagnostic performance in Cystic Echinococcoses (CE) as a complement tool to clear the inconclusive imaging data. Here, we comparatively evaluated the diagnostic value of Hydatid Fluid (HF) and the recently described recombinant multi-epitope antigen DIPOL in IgG-ELISA in a clinically defined cohort of CE patients. The serum samples from 149 CE patients were collected just before surgical or Percutaneous- Aspiration- Injection- Reaspiration (PAIR) procedures. Additionally, serum samples of patients with other parasitic infections (n=49) and healthy individuals (n=21) were also included in the study as controls. To investigate the association between the genotype of the parasite and DIPOL, cyst materials from 20 CE patients were sequenced. In terms of overall sensitivity, HF was higher than DIPOL (82.55%,78.52%, respectively). However, while the sensitivity of HF was higher than DIPOL in patients with active and transitional cysts (83.3%, 75.4%, respectively), sensitivity of DIPOL in inactive cysts was higher compared to HF (95.6%, 78.3%, respectively). The sensitivity of DIPOL depending on cyst stage was statistically significant (P= 0.041). In terms of specificity, DIPOL was found to be better than HF (97.71%, 91.43%, respectively). By genotyping, the majority of 20 patients showed G1 genotype (80%). All patients harboring G3 and G1/G3 cyst genotypes were positive with both antigens, while 87.5% of patients with G1 genotype were seropositive with HF and 75% with DIPOL. The overall sensitivity and high specificity of DIPOL suggest that this recombinant protein containing immunodominant epitopes is a potential substitute for the HF by serological tests for the diagnosis of CE.

Abstract
Cystic echinococcosis (CE) is a neglected zoonotic tropical disease caused by Echinococcus granulosus sensu lato. The aim of this study was to investigate the genetic variation of hydatid cyst isolates obtained from surgically confirmed paediatric cases originating from two different regions in eastern Turkey. Seventeen paediatric cases aged between 6 and 16 were operated by open surgery, and the germinal layers of their cysts were obtained for further molecular analyses. After genomic DNA isolation, 875 bp mt-CO1 gene fragments were amplified in all samples by PCR. Then, the unidirectional sequence analyses of the PCR products were carried out. According to the BLAST analyses of 17 sequences, 16 of these sequences were matched with E. granulosus sensu stricto, while one sequence was identified as E. canadensis (G6/G7) for the first time in paediatric cases in Turkey. High haplotype diversity and low nucleotide diversity were observed in the E. granulosus s.s. sequences.

Abstract
PURPOSE Hydatid cyst (HC) is a serious health problem in developing countries. The aim is to discuss the clinical information, surgical and puncture-aspiration-injection-re-aspiration (PAIR) treatments, and results of patients with HC in a developing country. METHODS Patients were analyzed in terms of gender, age, presenting complaint, misdiagnosed HC, cyst location, cyst number, cyst size, liver HC type according to the World Health Organization Informal Working Group Echinococcosis (WHO-IWGE) classification, pulmonary HC, hemithorax locations, treatments and interventions, duration of hospitalization, follow-up period, postoperative complications, and recurrence. RESULTS There were 106 girls and 99 boys with a mean age of 10.7 years. The most common location was the liver (n = 170), and the second most common was the lungs (n = 67). The mean diameter for liver HC was 86.27 mm, and it was 73.90 mm for pulmonary HC. PAIR was performed on 61 patients with liver HC using interventional radiology. 109 patients underwent surgery. The most common complications were cystobiliary fistula in liver HC and atelectasis in pulmonary HC. CONCLUSION HC should be one of the first considerations in the differential diagnosis in all anatomical areas in the presence of suspicious radiological and clinical findings in endemic regions.

Abstract
Surgery is still used as the first choice in the treatment of pulmonary hydatid cysts. Video-assisted thoracoscopic surgery (VATS) has started to be performed as a minimally invasive surgical option in recent years for lung hydatid cyst, few cases have been reported in the literature, especially in children. Thoracoscopic surgery experience is limited in pulmonary hydatid cyst for both adult and child patients. We present a pediatric case of giant lung hydatid cyst, in that we had partial capitonnage with VATS and fibrin glue.

Abstract
Background Different genotypes of Echinococcus granulosus sensu stricto (s.s.) isolated from livestock and humans have been identified based on cox1 and nad1 genomic fragments. The present study was performed to differentiate the G1/G3 genotypes of Echinococcus granulosus (s.s.) isolated from humans and livestock (sheep and cattle) from Azerbaijan in northwestern Iran, Fars Province in southern Iran, and Van province in Eastern Turkey, using the nad5 gene fragment as a suitable marker to distinguish these two genotypes. Methods A total of 60 pathologically confirmed human hydatid cysts and 90 hydatid cyst samples from livestock were collected from Turkey and Iran. PCR was performed on all of the samples, targeting the nad5 gene. Based on PCR product quality, host type, and the geographical area where the samples were obtained, 36 of the samples were sequenced and were used in the phylogenetic analysis. Results Out of 36 evaluated samples, 26 (72.2%) samples belonged to G1, and 10 (27.8%) samples belonged to the G3 genotype. Out of 21 samples from Turkey, 16 (76.2%) were G1 and 5 (23.8%) were G3, while out of 15 samples from Iran, 10 (66.7%) were G1 and 5 (33.3%) were the G3 genotype. None of the samples isolated from humans in Iran or from sheep in Turkey were G3. Overall, between the two countries, 18.18% of E. granulosus isolates in cattle, 41.66% of isolates in sheep, and 23.07% of human samples were identified as G3, and the others as the G1 genotype. The G3 genotype was not detected in human samples from Iran or sheep samples from Turkey. Conclusion The findings of the study revealed that the G1 genotype of E. granulosus s.s. is the predominant genotype in humans and livestock, both in Turkey and Iran. The ratio of the E. granulosus s.s. G1 to G3 genotype was 3.2 in Turkey and 2 in Iran. The study also further confirmed that the nad5 gene properly differentiated the G1/G3 isolates of E. granulosus from both humans and livestock. Graphical Abstract ![]()

Abstract
Echinococcosis is considered a cosmopolitan zoonosis caused by different species of small taeniid tapeworms of the genus Echinococcus and is regarded as a neglected zoonosis. Cystic and alveolar echinococcoses are endemic diseases of Tibetan, Pamir, and Iranian plateaus. All of the countries within the Iranian plateau are affected by echinococcosis. Pakistan, Turkey, and Iran are the three most populous countries of the region, in which echinococcosis is highly endemic. The three neighboring countries share strong cultural and socioeconomic ties. The present study aimed to provide a broad review of the status of cystic and alveolar echinococcosis, summarizing the current knowledge about geographical distribution, molecular epidemiology, and transmission dynamics of Echinococcus granulosus sensu lato and Echinococcus multilocularis in this region. Additionally, we aimed to understand disease burden and risk factors as basic requirements for establishing a surveillance system and planning prevention and control programs. A considerable body of information is available on different aspects of echinococcosis in this region; however, several information and research gaps need to be filled before planning control programs. None of the countries in the region have an elaborate echinococcosis control program. Effective control programs require multi/intersectoral coordination within a One Health approach with a long-term political and administrative commitment and enhanced international collaboration among the three countries.

Abstract
In Turkey, cyst hydatid disease (CHD) or cystic echinococcosis (CE) is publicly known as “dog cyst”, a fatal and serious disease not only affects livestock husbandry and human health but also brings about economic loss to our country. According to the data of the Ministry of Health; number of annual cases was 408 in 2008, and this number reached 1,867 by the end of 2019. Cystic echinococcosis is especially taken up during childhood and emerged at an older age. They become exposed to the eggs of the tapeworm after close contact with an infected dog or its contaminated environment. The infected dogs also pass in their feces E. granulosus eggs that adhere to the dogs’ hairs, and pass on to the children who are in the course of playful and intimate contact with the infected dogs. This study was to create the awareness of risk factors of CE among 10 different districts of Izmir province. Awareness raising seminars are essential component of this study because local people living in CE endemic areas, are crucial to continue and sustain the long-time effort that is needed to tackle this disease. In each district, 3 awareness raising seminars were held to the target groups: (a) in schools for students, teachers, administrators, (b) for general public, (c) for healthcare professionals. 4090 students attended to the trainings, 242 administrators and teachers who attended to the presentations together with the students, 524 people were attended to the trainings and 327 health workers attended to the trainings from different institutions. This study helped improving this situation by organising educational events for the rural populations for preventing transmission of the disease. This is the first educational intervention study regarding creating awareness on CE in Izmir Province which includes 10 districts between January 2019 to January 2020.

Abstract
Echinococcus multilocularis is a parasite species of zoonotic importance which can be fatal to humans and causes Alveolar Echinococcosis (AE). This report describes the development of a cyst from the liver of a wild boar and molecular confirmation of its identification. The cyst material was obtained from the liver of a wild boar killed by hunters. Genomic DNA was extracted from the germinal layer of the cyst material, and 875 bp mitochondrial cytochrome c oxidase subunit I (COI) gene fragment was amplified by PCR and sequenced. A BLAST search matched 100% with published Echinococcus multilocularis sequences. This study confirms the occurrence of E. multilocularis in a wild boar for the first time in Turkey.

Abstract
Cystic echinococcosis (CE) is one of the most common zoonotic diseases worldwide, particularly in rural areas. This study aimed at the identification of the genotype/species belonging to Echinococcus granulosus sensu lato (s.l.) specimens in retrieved percutaneously from the human host and to investigate their relationship with cyst characteristics. The genetic identification of cyst material was performed by mt-CO1 gene polymerase chain reaction, and confirmed via sequencing. A total of 110 CE cysts were identified as E. granulosus s.l. In detail, 104 belonged to E. granulosus sensu stricto (G1 and G3) and six isolates were in the E. canadensis cluster (G6/7). All clusters were tested for the relationship between demographics, cyst features and genetic diversity. The relationship between genetic variation and certain clinical characteristics such as cyst volume and location were statistically significant for G6/7 cluster. Further studies are required with a larger sample set to investigate the relationship between the genetic variability of E. granulosus s.l. and cyst features.

Abstract
Background Cystic echinococcosis (CE) is considered as a neglected disease with significant mortality and morbidity in most of the developing countries. The current study aimed to retrospectively assess the demographic and epidemiologic features of human CE surgical cases in a 15-year period in Fars province, southwestern Iran. Methods A 15-year (2004–2018) retrospective study was conducted to find out the epidemiological and clinical picture of CE in patients who undergone surgeries for CE in two main hospitals in Fars Province, southwestern Iran. Hospital records were reviewed, and data were retrieved from each CE patient’s record. Results A total of 501 CE surgical cases were recorded during a 15-year period, corresponding to an average annual incidence of 33.4 and a surgical incidence rate of 0.74/100,000 population. Of these, 242 (48.6%) were male, and 256 (52.4%) were female. Patients’ age ranged from 2 to 96 years, with a mean age of 34.92 (± 19.87) years. A significantly higher rate of CE cases was noted in subject’s ≥ 50 years of age. The highest frequency of cases (62:12.5%) was recorded in the year 2017. The most commonly involved organs were liver (339 cases; 57.8%) and lung (279 cases; 47.6%). Concurrent involvement of two organs was seen in 58 (9.9%) cases of both lung and liver, 10 (1.6%) cases of lung and other locations (but not liver), and 23 (3.9%) cases of liver and other locations (but not lung). Reoperation was noted in 67 (13.4%) of the cases. The size of the lung hydatid cyst varied, ranging between 2 and 24 cm (mean = 7.33, SD = 3.737). The size of liver hydatid cysts ranged from 1 to 26 cm (mean 9.04, SD = 4.275). Conclusion The findings of the current study demonstrated a nearly constant prevalence of CE during the last 15 years in southern Iran. Further studies are needed to find out the reasons behind the recurrence of the disease, which is substantial, in surgically-treated patients.

Abstract
Cystic echinococcosis (CE) is a zoonotic infection and could lead to significant public health problems. The genetic diversity of CE includes five species: E. granulosus sensu stricto (s.s.) (G1-G3), Echinococcus equinus (G4), Echinococcus ortleppi (G5), Echinococcus canadensis genotypic cluster (G6, G7, G8 and G10, with the doubtful G9) and the Echinococcus felidis (lion strain). The species are important in epidemiology, pathology, control, prevention measures and vaccine/drug designs. The aim of the present study was to determine the E. granulosus genotypes in humans in the Van province in east of Turkey. In total, 102 echinococcal cysts were collected from operated patients. Genomic analyses were conducted with PCR-RFLP of the rDNA internal transcribed spacer 1 (ITS1) fragment and partial PCR sequencing of the cytochrome c oxidase subunit 1 (cox1) mitochondrial DNA gene region. In total, DNAs of 96 isolates could be extracted, unfortunately six extractions failed. The PCR-RFLP analysis findings were identical in all isolates. Two bands were observed at approximately 300 bp and 600 bp. All profiles corresponded to the G1-G3 strain. Also, 446 bp amplified gene regions were observed for cox1. Out of 20 samples, alignment of 16 sequences exhibited a total identification (100%) of granulosus sensu stricto (G1/G3). Of 16 samples, 8 were obtained in the lung and 12 were obtained in the liver; 8 belonged to male and 12 belonged to female patients. Other four samples exhibited one nucleotide substitution at different positions. Four samples had one nucleotide substitution at different positions. We detected single nucleotide variations in TRH1, TRH67, TRH85 and TRH89 isolates at the positions C240T; G330T; G211A and T157C, respectively. In conclusion, the present study was the first comprehensive molecular investigation on genetic characterization of human CE isolates in Van region. The findings demonstrated that E. granulosus s.s. was the dominant species, which indicated that the sheep-dog cycle was the source in human infections. And, probably, it would be possible to describe these mutations as "Turkey" or "lung" variants. In addition to contributing molecular epidemiological data, the present results should be considered when designing and implementing E. granulosus control programs.

Abstract
Cystic echinococcosis (CE) is one of the most important zoonotic parasitic diseases caused by the larval stage of Echinococcus granulosus. Based on molecular studies and DNA sequencing, E. granulosus has been classified into 10 different genotypes (G1 to G10). Two neighboring countries, Turkey and Iran, are considered the two main foci of CE in the Middle East. The current study is aimed at examining the genotype diversity of E. granulosus isolated from human clinical samples in Turkey and Iran. Surgically removed human hydatid cysts were collected from East Azerbaijan and Fars provinces in Iran and Van province in Turkey. After extracting DNA, performing PCR, targeting the cox1 gene, the PCR products were purified from the gel and were sequenced from both directions. The sequences were aligned and compared, using BioEdit and also the BLAST program of GenBank. The maximum likelihood tree was constructed based on the Tamura-Nei model, using the MEGAX software. Phylogenetic analysis showed that the human isolated samples were classified into two major clades: G1 (from Iran and Turkey) and G3 (5 samples from northwestern Iran and one sample from Turkey). The mean and degree of genetic divergence (K2P) between the two major clades, G1 and G3, were 0.2% and 0.7 ± 0.4%, respectively. The findings of the current study revealed that the sheep strain (G1) and the less important strain G3 have major roles in the transmission cycle of CE in two neighboring countries, Iran and Turkey. Therefore, it is necessary to interpose the life cycle of this parasite and reduce the disease burden in livestock and humans by adopting common regional preventive and control policies.

Abstract
Erzurum province of Turkey is known to be highly endemic for alveolar echinococcosis (AE) and cystic echinococcosis (CE). In this study, we confirmed Echinococcus multilocularis cases, searched genetic variations of the isolates, and-for the first time-determined the genotypes of Echinococcus granulosus s.l. infecting humans in the province. A total of 5 alveolar and 106 hydatid cysts as well as 23 formalin-fixed paraffin-embedded (FFPE) samples that were diagnosed as AE were collected from hospitals between 2015 and 2017. Partial sequences of two mitochondrial genes were amplified to detect E. multilocularis and E. granulosus sensu lato with conventional polymerase chain reactions (PCRs) and genotypes confirmed by sequencing. PCR amplification of a partial 12S rRNA gene on an alveolar cyst and FFPE tissue samples yielded the expected bp in 5 cysts and 19 of 23 FFPE samples; all Erzurum E. multilocularis isolates were confirmed by sequencing. Phylogenetic analysis of the isolates indicated that some of them were identical to European isolates, whereas some of them were identical to Asian isolates. Off all hydatid cyst samples, 101 (95.2%) yielded the expected bp (94 with 12S rRNA-PCR and 7 with COI-PCR). Sequence analysis showed that 98 (97%) of them corresponded to the G1 genotype, whereas 3 (3%) corresponded to the G3 genotype. Results of the study emphasize that E. multilocularis isolates of Erzurum, based on short sequencing, are similar to both European and Asian isolates, and the G1 genotype of E. granulosus is the main causative agent of human CE in Erzurum.

Abstract
Intracranial hydatid cyst is a rare entity, comprising about 2-3% of all hydatid cysts. Similarly, intracranial hydatid cysts account for 1-2% of all intracranial lesions. Clinical symptoms are generally nonspecific and patients usually present with symptoms of increased intracranial pressure. Cerebral hydatid cysts can be either primary or secondary to systemic hydatid disease. Primary cerebral hydatid cysts are usually solitary, unilocular with an intraparenchymal location. Intraventricular extension of hydatid cysts account for a limited percentage of all cerebral hydatid cysts with limited number of cases reported. Herein, we present the imaging and surgical findings of a primary cerebral hydatid cyst that is located in frontal lobe parenchyma with partial extension into the ventricular system.

Abstract
OBJECTIVES Turkey remains among the countries where hydatid disease is endemic. In this study, it was aimed to determine the number of operations performed for the treatment of pulmonary hydatid disease in Turkey during 2014 and to present the distribution of these operations according to the different regions of the country. MATERIALS AND METHODS The Turkish Thoracic Society Thoracic Surgery Study Group connected with the thoracic surgeons in each city through telephone. A data set was sent by email. The age, sex, contact with animals that might be a risk of gaining the hydatid disease, the side of the disease, the type of surgical method, other organ involvement were recorded and collected from each data set to form the final data, and the results were evaluated. Turkey comprises of 81 cities that are grouped in seven different regions. The number of operations was calculated for each city and region to present the distribution. RESULTS Overall, 101 centers from 81 cities were considered in the study. A total of 715 pulmonary hydatid cyst operations were performed in 690 patients during the study period. The most common operation technique was cystotomy and capitonnage through thoracotomy (76%). The highest incidence rate of operated patients was in the Eastern Anatolian Region (2.15 patients per 100 000 person-years). CONCLUSION Pulmonary hydatid disease still has a high incidence rate particularly in the southeast and east of Turkey, which are mainly rural areas and where stockbreeding is very common. Cystotomy and capitonnage is still the most common surgical method used to treat pulmonary hydatid cysts. Preventive methods should be performed strictly in these cities and regions to decrease the risk of infection.

Abstract
Hydatid cysts usually arise in the liver and lungs but vary rarely in the forearm. We present a rare case of a solitary intramuscular forearm hydatid cyst in a young woman. We aim to increase the awareness of unusual sites for hydatid cysts. The cyst was attached to the median nerve and excised completely. This case was unique because of solitary nature and unusual location of the cyst.
Introduction Hydatid cyst is a parasitic disease caused by Echinococcus that is mostly found in the Mediterranean and Gulf States regions. Hydatid cysts usually arise in the liver and lungs but rarely occur in the forearm. Presentation of case In this report, we present a rare case of a solitary intramuscular forearm hydatid cyst in a 32-year-old woman. The cyst exhibited positive radiological findings and was treated surgically, leading to a complete resolution of the patient’s symptoms with no history of recurrence. Discussion This case was unique because although the patient presented in her fourth decade of life and lived in a Gulf country, the hydatid cyst was in a solitary and unusual location and had been present for one year. It had all positive findings in a radiological investigation without any signs of systemic illness. Additionally, the cyst was attached to the median nerve and a complete excision was performed without affecting the nerve. Conclusion By reporting this rare case of a solitary intramuscular forearm hydatid cyst, we aim to increase the awareness of unusual sites for the appearance of hydatid cysts.

Abstract
Backgrounds/Aims A wide range of surgical approaches has been described for hepatic hydatidosis aiming primarily at the reduction of disease recurrence and minimization of postoperative morbidity. Methods A database analysis of patients with liver hydatidosis who underwent different surgical procedures between March 2010 and May 2016 was performed. Results A total of 21 patients with cystic echinococcosis (CE) and four cases of alveolar echinococcosis (AED) were detected. Nine patients manifested recurrent disease at presentation. Among CE cases, 5 underwent partial cystectomy (2 laparoscopic and 3 open), 9 cysto-pericystectomy (7 open and 2 robotic) and 7 hepatectomies (1 central, 4 right, 1 left and 1 right trisectionectomy). Living donor liver transplantation was performed in 3 patients with AED and the fourth patient underwent right trisectionectomy with en bloc resection of hepatic flexure and right diaphragm. Seven developed Clavien grade II and three grade III complications. The mean follow-up of CE was 34.19±19.75 months. One patient of laparoscopic partial cystectomy developed disease recurrence at 14 months. No recurrence was detected at a mean follow-up of 34±4.58 months following LDLT and at 24 months following multivisceral resection for AED. Conclusions The whole spectrum of tailored surgical approaches ranging from minimally invasive to open and extended liver resections represents safe, effective and recurrence-free treatment of hepatic hydatidosis.

Abstract
OBJECTIVES To determine the knowledge, attitudes, practices, and awareness for risk factors associated with cystic echinococcosis (CE) among animal breeders, nurses, nursing students, dietitians, food professionals and other public groups in Turkey. Methods: Questionnaire forms were prepared in compliance with the individuals' diversity, and a survey was created about agents, transmission modes, epidemiology, treatment, and risk factors for CE. The descriptive survey was performed between May 2015 and May 2016 by face-to-face communication. Data were collected from a total of 647 individuals, including 95 animal breeders, 92 nurses, 249 nursing students, 49 dietitians, 28 food professionals and 134 people from other public groups from Turkey. Survey data were evaluated in terms of percentages and means and analyzed by the Pearson's chi-square test and Mann-Whitney U test to determine the relationships between questionnaire answers and socio-demographic attributes, such as age, gender, educational level, and profession. Non-categorical variables were compared via Spearman's rho correlation analysis with statistical significance set at the 0.05 level. Results: We determined low awareness for vegetable washing, raw vegetables and offal consumption, informative courses, contact with dogs, and administration of antiparasitic drugs to dogs. Conclusion: The participants of this survey were found to be with insufficient knowledge regarding risk factors of CE. We advocate the implementation of training programs to improve public awareness on this important disease.

Abstract
Cystic echinococcosis caused by the larval stages of Echinococcus granulosus sensu lato s.l is endemic in Turkey with a high public health impact particularly in rural areas. The aim of this study was to investigate the genetic variation and population structure of E. granulosus s.s using metacestode isolates removed from surgically confirmed patients originating from several regions in Turkey and to investigate the occurrence of autochthonous transmission. Using DNA extracted from a total of 46 human-derived CE isolates, we successfully analysed an 827-bp fragment within the cox1 mitochondrial gene and confirmed the causative agent of human cystic echinococcosis in patients included in this study to be Echinococcus granulosus s.s (G1 and G3 genotypes). The haplotype parsimony network consisted of 28 haplotypes arranged within three main clusters and the neutrality indices were both negative and significant indicating negative selection or population expansion. The assessment carried out in this study using GenBank nucleotide sequence data from Turkey for sheep and cattle hosts demonstrated the importance of autochthonous transmission with sheep, cattle and humans harbouring the same haplotypes. Further studies are required to investigate the biological significance, if any, of E. granulosus s.s haplotypes and the genetic variability of CE from human patients using longer nucleotide sequences and a larger sample set.

Abstract
AbstractEchinococcus multilocularis is the causative agent of alveolar echinococcosis (AE), one of the most threatening zoonoses in Eurasia. Human AE is widespread in the Erzurum region of Turkey, but the situation of the disease in intermediate and definitive hosts is unknown. A Eurasian lynx (Lynx lynx) was killed in a traffic accident in the north of Erzurum, and was taken to our laboratory. Sedimentation and counting technique (SCT), DNA isolation and polymerase chain reaction (PCR) analysis were performed. The SCT results showed that the lynx was infected with E. multilocularis with a medium (745 worms) worm burden. The DNA of adult worms obtained from the lynx was analyzed with a species-specific PCR, and the worms were confirmed to be E. multilocularis by 12S rRNA gene sequence analysis. This is the first report of E. multilocularis from Eurasian lynx in Turkey.

Abstract
Cystic echinococcosis (CE) is an endemic helminthic disease caused by infection with Echinococcus granulosus metacestodes. Although CE is endemic in the Balkan region, the exact epidemiology remains unknown. We conducted a case-series study with the aim of evaluating the correlation between seropositivity, socio-epidemiological data, pre-operative treatment with albendazole and viability of protoscolices in human hepatic hydatid cysts. Consecutive patients with hepatic CE underwent surgery to extract E. granulosis cysts. The viability of protoscolices was measured by their ability to absorb 0.1% eosin. Socio-epidemiological data were collected and serological testing was performed. In the present study, 38 patients (28 adults and 10 children) with hepatic CE were treated surgically. The scolex viability test was positive in 30/38 (79%) samples. All patients with non-viable cysts had seronegative results. The viability test was positive in 11/12 (91.6%) adult patients with pre-operative albendazole treatment and in 9/10 (90%) children. Statistically more patients were from an urban area compared with a rural area (65.8% vs. 15.7%). The increasing number of stray dogs shedding E. granulosus eggs in urban public areas in the Balkans might be the reason for the significant difference in the rate of infection between urban and rural areas in the present study. In addition, uncontrolled slaughtering of livestock, common in rural settlements, and feeding the infected viscera to dogs, favour the maintenance of the parasite cycle. We believe that the results of our study will encourage physicians, veterinarians and health authorities to initiate a programme to prevent and control CE in the Balkan region.

Abstract
The larval stage of Echinococcus granulosus causes cystic echinococcosis (CE), a neglected tropical disease that leads to morbidity and mortality in humans and livestock worldwide. Here, we identified and characterized dihydrofolate reductase (Eg-DHFR) from E. granulosus, and evaluated its potential as a diagnostic antigen for sheep CE. Comparison between mammalian (host) DHFR and Eg-DHFR indicates that 45.7% of the 35 active site residues are different. Immunolocalisation analysis showed that native Eg-DHFR was widely distributed in all life-cycle stages of E. granulosus. Recombinant Eg-DHFR (rEg-DHFR) showed typical DHFR enzymatic parameters towards substrate, and was very sensitive to inhibition by methotrexate (IC50 = 27.75 ± 1.03 nM) and aminopterin (IC50 = 63.67 ± 6.76 nM). However, inhibition of DHFR exhibited little protoscolicidal effect in vitro. As there is no reliable method to monitor sheep CE, the immunogenicity of rEg-DHFR was detected, and we developed an indirect ELISA (iELISA) for CE serodiagnosis. The iELISA exhibited diagnostic specificity of 89.58%, diagnostic sensitivity of 95.83%, and the diagnostic accuracy was 91.67% compared with necropsy. Cross-reactivity assay showed analytical specificity of 85.7%. These suggest that rEg-DHFR is an effective antigen for the diagnosis of sheep CE.

Abstract
Alveolar echinococcosis (AE) and cystic echinococcosis (CE) are severe helminthic zoonoses. Echinococcus multilocularis (causative agent of AE) is widely distributed in the northern hemisphere where it is typically maintained in a wild animal cycle including canids as definitive hosts and rodents as intermediate hosts. The species Echinococcus granulosus, Echinococcus ortleppi, Echinococcus canadensis and Echinococcus intermedius are the causative agents of CE with a worldwide distribution and a highly variable human disease burden in the different endemic areas depending upon human behavioural risk factors, the diversity and ecology of animal host assemblages and the genetic diversity within Echinococcus species which differ in their zoonotic potential and pathogenicity. Both AE and CE are regarded as neglected zoonoses, with a higher overall burden of disease for CE due to its global distribution and high regional prevalence, but a higher pathogenicity and case fatality rate for AE, especially in Asia. Over the past two decades, numerous studies have addressed the epidemiology and distribution of these Echinococcus species worldwide, resulting in better-defined boundaries of the endemic areas. This chapter presents the global distribution of Echinococcus species and human AE and CE in maps and summarizes the global data on host assemblages, transmission, prevalence in animal definitive hosts, incidence in people and molecular epidemiology.

Abstract
The genus Echinococcus is composed of eight generally recognized species and one genotypic cluster (Echinococcus canadensis cluster) that may in future be resolved into one to three species. For each species, we review existing information on transmission routes and life cycles in different geographical contexts and - where available - include basic biological information of parasites and hosts (e.g., susceptibility of host species). While some Echinococcus spp. are transmitted in life cycles that involve predominantly domestic animals (e.g., dog - livestock cycles), others are wildlife parasites that do or do not interact with domestic transmission. In many cases, life cycle patterns of the same parasite species differ according to geography. Simple life cycles contrast with transmission patterns that are highly complex, involving multihost systems that may include both domestic and wild mammals. Wildlife transmission may be primary or secondary, i.e., resulting from spillovers from domestic animals. For most of the species and regions, existing information does not yet permit a conclusive description of transmission systems. Such data, however, would be highly relevant, e.g., for anticipation of geographical changes of the presence and frequency of these parasites in a warming world, or for initiating evidence-based control strategies.

Abstract
Echinococcus granulosus is the causative agent of cystic echinococcosis. The disease is a significant global public health concern and human infections are most commonly associated with E. granulosus sensu stricto (s. s.) genotype G1. The objectives of this study were to: (i) analyse the genetic variation and phylogeography of E. granulosus s. s. G1 in part of its main distribution range in Europe using 8274 bp of mtDNA; (ii) compare the results with those derived from previously used shorter mtDNA sequences and highlight the major differences. We sequenced a total of 91 E. granulosus s. s. G1 isolates from six different intermediate host species, including humans. The isolates originated from seven countries representing primarily Turkey, Italy and Spain. Few samples were also from Albania, Greece, Romania and from a patient originating from Algeria, but diagnosed in Finland. The analysed 91 sequences were divided into 83 haplotypes, revealing complex phylogeography and high genetic variation of E. granulosus s. s. G1 in Europe, particularly in the high-diversity domestication centre of western Asia. Comparisons with shorter mtDNA datasets revealed that 8274 bp sequences provided significantly higher phylogenetic resolution and thus more power to reveal the genetic relations between different haplotypes.

Abstract
This study aimed to find out the occurrence of Echinococcus multilocularis in foxes in Erzurum province, the highest endemic region for human alveolar echinococcosis in Turkey. The sedimentation and counting technique was used to reveal adult Echinococcus spp. in the intestines of foxes. One out of the 10 foxes was infected with E. multilocularis. The adult worms were analyzed morphologically and molecularly and were confirmed to be E. multilocularis by species-specific PCR. Pairwise comparisons between the 12S rRNA sequences of the E. multilocularis isolate from Erzurum and other E. multilocularis isolates showed 100% similarity of the Erzurum isolate with European isolates. With this study, the presence of E. multilocularis in a fox in Erzurum was confirmed by PCR, and molecular identification of E. multilocularis is reported for the first time in Turkey.

Abstract
Hydatid cyst is one of the five most diagnosed zoonotic diseases in the Mediterranean region. However, intramuscular localisation is very rare. It is reported that muscular involvement constitutes 1-5.4% of all Echinococcus infections. Here we would like to report an unusual case of hydatid cyst in the gluteus muscle, which had been treated with both surgical and medical treatment.

Abstract
Alveolar echinococcosis (AE) is a chronic disease caused by ingestion of the eggs of the parasitic cestode Echinococcosis multilocularis (EM). In severe cases, liver transplantation (LT) may represent the only possibility of survival and cure. Patients undergoing LT associated with hepatic AE at our institution between April 2011 and October 2014 were investigated retrospectively. The clinical findings of the 27 patients who participated in the study were noted. Kaplan-Meier and chi-square tests were used to investigate the effect of these characteristics on survival and mortality. Living donor LT was performed on 20 patients (74.1%), and deceased donor LT was performed on 7 patients (25.9%). Hilar invasion was the most common indication (14 patients, 51.9%) for transplantation. The patient follow-up was 16.1 ± 11.4 months, and the overall survival rate was 77.8%. Primary nonfunction developed only in 2 patients in the posttransplantation period. Six patients died during monitoring, the most common cause of death being sepsis (3 patients). The relationship between the mortality rate of the patients and the invasion of the bile duct and/or portal vein by alveolar lesions was found to be statistically significant (P = 0.024 and P = 0.043, respectively). According to PNM staging, when the AE disease exceeds the resectability limits, the only alternative for the treatment of the disease is LT. However, different from LT due to cirrhosis, it is extremely difficult to perform a transplantation for AE disease because of the invasive characteristics of it. In order to decrease the difficulty of the operation and the postoperative mortality, the intracystic abscess and cholangitis which occur because of AE must be treated via medical and percutaneous methods before transplantation.

Abstract
Hydatid cyst, a common disease in the world, is usually transmitted to humans through dog feces. Hydatid cyst is caused by Echinococcus granulosus. Diagnostic interventions for hydatid cyst include physical examination and chest x-ray tomography. Although the treatment options of hydatid cyst vary according to the clinical findings of the patients, the primary treatment may be considered as surgery. We herein reported the case of a child hospitalized due to pneumonia who developed anaphylaxis as a result of the rupture of a pulmonary hydatid cyst.

Abstract
Human cystic echinococcosis (CE) is an endemic disease in the Mediterranean area that has not yet been fully documented in western Libya. The present study describes the clinico-epidemiologic profile of CE in western Libya’s Nalut district. From April 2008 to July 2011, 36 cases of CE were confirmed following surgical removal of cysts. The cysts were most frequently found in the liver (61.1%), followed by the lungs (19.4%), kidneys (11.1%), peritoneal cavity (11.1%), and spleen (5.6%). Among the 36 patients, 6 possessed plural cysts and 3 had cysts in 2 organs. Blood samples from this group were examined for the presence of serum anti-hydatid IgG antibodies, which revealed positivity in 25 patients (69.4%). An additional 300 blood samples were collected randomly from the inpatient and outpatient clinics at Nalut Hospital. Twenty-seven samples (9%) were found to be positive for the anti-hydatid IgG antibody among which the prevalence of infection tended to be higher in men (12%) than in women (6%). This study demonstrates that CE is a major parasitic infectious disease of public health significance in Libya, notably in the western part of the country, and that disease awareness needs to be raised nationwide.

Abstract
Hydatid disease is an endemic infection which can affect any organ, mainly the liver and lungs. Peritoneal echinococcosis is usually known to occur secondary to hepatic hydatid cyst rupture into the peritoneal cavity. An isolated cyst in the pelvic cavity is considered as primary only when there are no other hydatid cysts. Herein, we report an isolated pelvic-cervical hydatid cyst which presented without any involvement of the other abdominal organs or lungs. Our patient, a 27-year-old woman with the primary complaints of dyspareunia and chronic pelvic pain, had thin-walled large cystic mass originating from the cervix, diagnosed by ultrasonography. She underwent surgery with the most likely initial diagnosis of exophytic fibroid with cystic degeneration. Gynecologists should be aware of the possibility of isolated primary hydatid cyst of the pelvic cavity and should consider this condition in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

Abstract
Cystic echinococcosis (CE) is one of the most important zoonotic diseases in a wide geographic area, including Turkey. In the present project, a total of 4275 students from Celal Bayar University, Manisa, Turkey, were screened by ultrasonography (US) and specific antibodies for CE were examined by Western blotting (WB) and ELISA in finger prick blood samples of 2034 of 4275 volunteered students. We aimed to report the apparent prevalence of CE based on different diagnostic procedures and to compare WB and ELISA with US in diagnosis of CE in a mass screening setting. Six new cases were diagnosed as CE by US during the survey. In addition to these cases, three students were also detected to have been previously operated and pathologically confirmed for hepatic CE. US revealed parenchymal changes in these cases in concordance with their operation history; so, the prevalence of CE by US was calculated as 0.21% (9/4275) (95%CI, 0.11-0.39%) among university students in Manisa. Bands were detected at 8, 28, 32, 38, 42, 47, 70 and 90kDa by WB and the cases were considered to be positive for CE when at least three of the bands were seen together. Apparent prevalence of CE by ELISA and WB were found to be 2.11% (43/2034) (95%CI, 1.57-2.83%) and 0.25% (5/2034) (95%CI, 0.10-0.57%), respectively. Of the six US positive cases, WB was positive in only one case with two cysts in the liver. All of four cases with liver involvement were positive by ELISA. The high prevalence of CE among university students in Manisa indicated that CE is a major health problem in this area of Turkey. Our results supported that WB is rather difficult and not feasible as a mass screening test and may not be effective for confirmation especially in asymptomatic cases. As a result, we recommend US to be used initially in mass screening surveys for CE followed by confirmation by ELISA for suspected cases. Further examination primarily by chest X-ray followed by computed tomography and/or magnetic resonance imaging, if needed, should be recommended for US negative, ELISA and WB positive individuals who may have non-abdominal cysts.

Abstract
AE is a parasitic disease caused by Echinococcus multilocularis (E.m.). AE is a rare form of echinococcosis and mostly seen in 50- to 70-yr-old patients. Its asymptomatic invasive tumor-like lesion development period, which lasts as much as 20 yr, is too long. Hence, this disease is very rare in children. Herein, we report an AE in a 12-yr-old girl who was not eligible for surgical treatment because of a radiological evaluation of non-resectable lesion and was scheduled for a LT.

Abstract
Urinary hydatidosis is very rare and represents 2% to 4% of all cases of cystic echinococcosis. We present a case of a 21-year-old man with symptoms of frequency, urinary retention and reduced force in urinary stream due to cystic echinococcosis. Anti-Echinococcus granulosus antibodies were determined by echinococcosis western blotting, and pelvic computed tomography revealed a 11 × 14 × 10-cm retrovesical homogeneous cystic mass. The patient underwent surgical intervention; the cystic mass and retrovesical cavity were removed. After a 3-year follow-up period, there was no episode of lower urinary tract symptoms. This case illustrates that cystic echinococcosis should be considered in every case of cystic mass, especially in endemic countries, such as Turkey.

Abstract
The tapeworm Echinococcus granulosus constitutes a major public health concern, since its larval stage causes cystic echinococcosis (CE) which is a life-threatening zoonotic disease in many parts of the world. The purpose of the present study was to perform a screening study in order to investigate the prevalence and risk factors of CE using a portable ultrasound (US) in a representative sample of 2500 primary school children aged 7-14 in East Turkey, where CE is known to be endemic. The students were scanned by portable US while standing, with special attention to the liver, spleen, pancreas, and kidneys. The US scan was followed by a physical examination. In addition, a questionnaire was distributed to all students for completion with the assistance of their teachers regarding their demographic and social characteristics as well as their hygienic habits possibly related to CE. Students found positive were subjected to serologic examination. The US based prevalence was 0.2%. Organ involvement was 0.12% for liver and 0.08% for kidney. The response rate of the questionnaire survey was 93%. The risk factors found to be significant (P<0.05) for CE infection were hand washing and family relative with CE. The results of this study indicate that CE infection is an important public health problem in East Turkey requiring appropriate control measures.
