Abstract
Background Helicobacter pylori isa universal pathogen that causes gastric diseases and cancers in humans. In recent years, several virulence genes have been detected in this microorganism. Thus, we aimed to investigate the frequency of Helicobacterpylori strainswith cytotoxin-associated gene A(cagA) and outer membrane inflammatory protein A(oipA) genotypes among children and adult patients in Tehran, Iran, and evaluatetheir relation to themanifestations of different clinical symptoms. Methods In this cross-sectional study, biopsy specimens were obtained from patients with gastrointestinal symptomsand evaluated for Helicobacter pylori infectionand its genotypes (cagA/oipA) througha polymerase chain reaction PCR assay. Clinical findings and demographic data of patients were documented and analyzed. Results A total of 80 patients with Helicobacter pylori infectionwere included in the study (34 children and 46 adults). The cagA and oipA genotypes of Helicobacter pylori wereidentified in 22 (64.7%) and 24 (70.5%) children and in 31 (67.3%) and 34 (73.9%) adults, respectively. These differences were not statistically significant between the 2 studied groups. In addition, the frequency of cagA-positive strains of Helicobacterpylori wasfound more among patients with gastric ulcers rather than other clinical outcomes. Conclusion Our findings demonstrate a highfrequency of Helicobacter pylori strains with oipA and cagA genotypes among children and adults in this region. Although we could not find a significant relationship between virulence genes and clinical outcomes in the patients, further studies are suggested to evaluate these factors in patients and assess their potential roles in the presence of antibiotic-resistant strains.

Abstract
The prompt detection of human papillomavirus and discrimination of its genotypes by combining conventional methods in new molecular laboratories is essential to achieve the global call of eliminating cervical cancer. After predicting the melting temperature of an approximately 221 bp region of the L1 gene from different HPV genotypes by bioinformatics software, an innovative technique based on the nested- high resolution melting was designed with three approaches and using conventional PCR, qPCR, and diagnostic standards. HPV-positive samples identified by microarray along with diagnostic standards were evaluated by qPCR-HRM and discordant results were subjected to sequencing and analyzed in silico using reference types. In addition to screening for human papillomavirus, nested-qPCR-HRM is one of the modified HRM techniques which can discriminate some genotypes, including 6, 16, 18, 52, 59, 68 and 89. Despite the differences in diagnostic capabilities among HRM, microarray and sequencing, a number of similarities between HRM, and sequencing were diagnostically identified as the gold standard method. However, the bioinformatics analysis and melting temperature studies of the selected region in different HPV genotypes showed that it could be predicted. With numerous HPV genotypes and significant genetic diversity among them, determining the virus genotype is important. Therefore, our goal in this design was to use the specific molecular techniques with several specific primers to increase sensitivity and specificity for discriminating a wide range of HPV genotypes. This approach led to new findings to evaluate the ability of different approaches and procedures in accordance with bioinformatics.

Abstract
Substantial evidence is available on the capacity of particular strains of Epichloë fungal endophyte to remove the barriers of self-pollination in host grasses. We hypothesized that this might open up new methods to obtain inbred lines for specific turf hybrids and genetic studies. In the present study, we evaluated the first generation of self-pollination derived plants of endophyte infected clones (EIS1 ) from putative genotypes 75B+ and 75C+ and those from the first generation of self-pollination in six commercial tall fescue clones plus their hybrids with 75B- and 75C- for growth, seed yield and polyphenolic content as an index for biosynthesis of defence compounds under field conditions. The results showed that EIS1 had high hyphal density within leaf sheaths and higher growth and seed-related traits in at least one genotype. There were higher amounts of flavonoid and phenolic compounds (up to twofold) in both genotypes than in their hybrid counterparts and endophyte-free progeny. Selected genotypes within EIS1 contained significantly more chlorogenic acid, p-coumaric acid and rutin than the best non-infected genotypes. We conclude that phenotypic selection of individuals from the S1 population is feasible for improving fitness and stress resistance in novel inbred lines of tall fescue for development of new turf cultivars with the desired ecophysiological traits.

Abstract
BACKGROUND Toxoplasmosis is a zoonotic disease caused by the parasite Toxo-plasma gondii, a cosmopolitan intracellular parasite. It can be a risk factor for auto-immune diseases, including rheumatoid arthritis (RA). This study was designed to investigate the possible association between serological history of T. gondii infection and defined clinical manifestation of RA in Northeast of Iran. METHODS Overall, serum samples were collected from 50 RA patients and 40 healthy controls, from Qaem Hospital in Mashhad City, northeastern Iran in 2018. Seroprevalence of T. gondii infection was determined by ELISA. RESULTS The prevalence of anti -T. gondii IgG in RA patients 48% (24.50) was significantly higher than the control group 10% (4.40) (P <0.001). Erythrocyte sedimentation rate (ESR), anti-cyclic citrullinated peptide (anti-CCP) and (rheumatoid factor) RF levels between the RA and control groups (P <0.01). Control group were matched with patients for age, gender and living area. CONCLUSION Given that a high correlation has been demonstrated between positivity rate of anti-T. gondii IgG and RA in Northeastern Iran, further studies will be necessary to clarify the pathogenesis of T. gondii among these patients.

Abstract
Background: This study was conducted to determine the prevalence and intensity of nematode infections in sheep located in northeastern Iran from Apr 2018 to Mar 2019.
Methods: Gastrointestinal nematodes of 300 sheep were inspected. The season of slaughter, anatomic location where the parasite was located, the animal’s sex, infection prevalence and intensity were recorded. Seasonal differences in arrested larvae numbers also were assessed using Cochran's Q test.
Results: Overall, 4,331 adult nematode specimens were collected. Among the examined sheep, 53% (159/300) were infected with one or more nematode species. Among infected sheep, 42.8% were infected with a single species of nematode, 26.4% were infected with two species of nematodes, and 30.8% were infected with three or more species of nematodes. Marshallagia marshalli (13.3%) was the most common nematode recovered from the abomasums of infected sheep, while Trichostrongylus vitrinus (4.6%) was commonly recovered from the small intestines, and Trichuris ovis (25.6%) was commonly recovered from the large intestines. In total, 463 arrested larvae were found in the abomasums of 7.5% of infected sheep and 104 arrested larvae were found in the small intestines of 8.8% of infected sheep. A significantly higher numbers of arrested larvae were found in summer compared to autumn (P<0.001).
Conclusion: Intestinal parasites continue to be a problem for sheep in northeastern Iran and additional control measures need to be explored.

Abstract
This study aimed to review published scientific literature on bed bugs in countries where insecticide resistance has been reported worldwide from 2000 to 2021. Electronic databases, including Scopus, PubMed, and WOS, were searched. Out of 606 articles found in the initial search, we selected 57 articles, of which 40 articles had reported on Cimex lectularius (C. lectularius), and 22 papers had reported on Cimex hemipterus (C. hemipterus). Most studies on insecticide resistance were carried out on C. lectularius in North America (14, 35%) and C. hemipterus in Asia (16, 72.7%). The most common method used to detect bed bug resistance to insecticides was toxicological bioassay with an overall random pooled effect size of 0.38 (95% CI: 0.23-0.53) in C. lectularius and 0.46 (95% CI: 0.27-0.65) in C. hemipterus. Resistance to pyrethroids was reported against C. lectularius with an overall pooled effect size of 0.75 (95% CI: 0.56-0.94) and C. hemipterus with an overall pooled effect size of 0.81 (95% CI: 0.57-0.93) in 33.40 (82.5%) and 19.22 (86.3%) published articles, respectively. A very high resistance level to pyrethroids in both studied species was observed, and resistance ratios at the highest level were 76389.3 and 315.5 in C. lectularius and C. hemipterus, respectively. Resistance mechanisms against pyrethroids were reported from most locations except Iran and Thailand, but these mechanisms were not studied in other insecticide groups. These reports indicate that chemical control options for bed bugs are limited. Therefore, a combination of chemical and non-chemical strategies is recommended for bed bug control.

Abstract
Malaria is one of the most serious health problems in many countries, including Iran. Accurate diagnosis is important regardless of the elimination status of a country. A cross-sectional study was performed on 105 people who were suspected to be positive for malaria infection in Sistan and Baluchistan, Iran. Blood smears (thin and thick films) were stained with 10% Giemsa. DNA was extracted from the prepared thin and thick films for molecular methods. Multiplex/nested polymerase chain reaction (mn-PCR), loop-mediated isothermal amplification (LAMP), and light microscopy (LM) were compared with nested PCR (nPCR) as a gold standard. Of 105 subjects, 52 (49.5%), 58 (55.2%), 58 (55.2%), and 63 (60%) were positive for malaria by LM, nPCR, mn-PCR, and LAMP, respectively. The sensitivity, specificity, and kappa were 92.1%, 100%, and 0.9 for LAMP and 100%, 100%, and 1 for mn-PCR, respectively. Eight cases of coinfection (Plasmodium vivax and Plasmodium falciparum) that were not detected by LM method were diagnosed by mn-PCR and LAMP. In the present study, the high sensitivity and specificity of LAMP and mn-PCR indicate that these two tests are good alternatives to nPCR for malaria diagnosis.

Abstract
Background: Phthalates are main ingredients of polyethylene terephthalate (PET) bottles used for storage of water. These compounds can cause adverse effects on human health. The purpose of this study was the quantification of the amounts of phthalates migrated in bottled water as well as the risk assessment of those compounds.
Methods: This cross sectional study was performed on 15 PET bottled water samples of popular brands distributed in Isfahan city, Iran. The samples were immediately sent to laboratory for analysis. Amounts of Phthalic Anhydride (PA), di-2 ethylhexyl phthalate (DEHP), di-buthyl phthalate (DBP), di-ethyl phthalate (DEP), and terphthalic acid (TPA) in bottled water samples were measured using Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Risk assessment of migrated compounds were calculated and com- pared with Hazard Quito (HQ) standards.
Results: The ranges of PA, DEHP, DBP, and TPA were 2.3-26, 171-845, 30-2251, and 24-657 ppb, respectively. DEP was not found in none of the analyzed samples. HQ levels of DEHP, TPA, and DBP were more than 1 in bottled water.
Conclusion: In the current study, the concentration of DEHP, TPA, and DBP in some bottled water of Isfahan, Iran were higher than the permitted limits. Also, HQ levels of these three migrated compounds were more than 1 in bottled water that is alarming for public health in this region of Iran.

Abstract
Background Platyhelminth infections of livestock can result in considerable economic losses. This study aims to evaluate the spatial frequency of cystic echinococcosis (CE), dicrocoeliasis, and fascioliasis in livestock slaughtered in Iran during the years 2015–2019 and estimate direct costs associated with organ condemnation due to these parasites. Methods Abattoir data from 413 abattoirs representing all 31 Iranian provinces were collected from the Iran Veterinary Organization. Infection prevalence was calculated per year at the province level. The Local Moran’s I statistic was performed to evaluate spatial autocorrelation of animals positive at slaughter for the years 2015–2019. Direct costs associated with condemned livers were calculated for each parasitic condition, with costs associated with condemned lungs also included for CE. Results Overall prevalence values for the study timeframe were as follows: sheep and goat fascioliasis 1.56% (95% CI: 1.56–1.56%), cattle fascioliasis 3.86% (95% CI: 3.85–3.88%), sheep and goat dicrocoeliasis 4.63% (95% CI: 4.62–4.63%), cattle dicrocoeliasis 3.08% (95% CI: 3.07–3.09%), sheep and goat CE 5.32% (95% CI: 5.32–5.33%), and cattle CE 7.26% (95% CI: 7.24–7.28%). Northwest Iran had the highest prevalence of CE and fascioliasis. High infection areas for Dicrocoelium spp. included the provinces of Zanjan, Gilan, Qazvin, and Tehran, which are located in northern Iran. Direct economic losses for sheep and goat fascioliasis, dicrocoeliasis, and CE for the study period were US$13,842,759, US$41,771,377, and US$22,801,054, respectively. Direct economic losses for cattle fascioliasis, dicrocoeliasis, and CE for the study period were US$1,989,200, US$1,668,986, and US$2,656,568, respectively. Conclusion Our findings provide valuable data for future monitoring of these important parasitic diseases in Iranian livestock. Disease control strategies are required to reduce the economic and public health impact of these platyhelminths.

Abstract
Felidae as definitive hosts for Toxoplasma gondii play a major role in transmission to all warm-blooded animals trough oocysts dissemination. Therefore the current comprehensive study was performed to determine the global status of T. gondii infection in domestic and wild felids aiming to provide comprehensive data of interest for further intervention approaching the One Health perspective. Different databases were searched by utilizing particular key words for publications related to T. gondii infecting domestic and wild feline host species, worldwide, from 1970 to 2020. The review of 337 reports showed that the seroprevalence of T. gondii in domestic cats and wild felids was estimated in 37.5% (95% CI 34.7-40.3) (I2 = 98.3%, P < 0.001) and 64% (95% CI 60-67.9) (I2 = 88%, P < 0.0001), respectively. The global pooled prevalence of oocysts in the fecal examined specimens from domestic cats was estimated in 2.6% (95% CI 1.9-3.3) (I2 = 96.1%, P < 0.0001), and that in fecal samples from wild felids was estimated in 2.4% (95% CI 1.1-4.2) (I2 = 86.4%, P < 0.0001). In addition, from 13,252 examined soil samples in 14 reviewed studies, the pooled occurrence of T. gondii oocysts was determined in 16.2% (95% CI 7.66-27.03%). The observed high rates of anti-T. gondii antibodies seroprevalence levels and oocyst excretion frequency in the felids, along with soil (environmental) contamination with oocysts may constitute a potential threat to animal and public health, and data will result of interest in further prophylaxis programs.

Abstract
Pediculosis by Pediculus humanus capitis is still an important health issue in school-age students worldwide. Although pediculicidal agents effectively kill head lice, the re-infestation rate is still high. This study was conducted to provide a summary of evidence about the prevalence of pediculosis capitis among school-age students worldwide. Different databases including MEDLINE/PubMed, Scopus, and Web of Science were searched for publications related to pediculosis capitis in school-age students from 1977 to 2020. All peer-reviewed original research articles describing pediculosis capitis among school-age students were included. Statistical heterogeneity of the different years among studies was assessed using the standard chi squared and I2 tests. Due to the significant heterogeneity, a random effect model was adopted to estimate the pooled, continent, and gender-specific prevalence of pediculosis. Two hundred and one papers met the inclusion criteria of this review and entered into the meta-analysis including 1,218,351 individuals. Through a random effect model, the prevalence of pediculosis capitis among school students was estimated as 19% (CI 95% = 0.18-0.20%, I2 = 99.89%). The prevalence of pediculosis capitis among boys was 7% (CI 95% = 0.05-0.10) compared to 19% (CI 95% = 0.15-0.24) in girls. The highest prevalence was in Central and South America (33%, CI 95% = 0.22-0.44, I2 = 99.81%) and the lowest was in Europe (5%, CI 95% = 4-6, I2 = 99.28%). Relatively high pediculosis capitis prevalence among school-age students observed in this study emphasizes the need for implementing screening and prophylaxis tailored to the local context.

Abstract
Cryptosporidium is one of the major causes of diarrhea in HIV-positive patients. The aim of this study is to systematically review and meta-analyze the prevalence of Cryptosporidium in these patients. PubMed, Science Direct, Google Scholar, Web of Science, Cochrane and Ovid databases were searched for relevant studies dating from the period of 1 January 2000 to 31 December 2017. Data extraction for the included studies was performed independently by two authors. The overall pooled prevalence was calculated and subgroup analysis was performed on diagnostic methods, geographical distribution and study population. Meta-regression was performed on the year of publication, proportion of patients with diarrhea, and proportion of patients with CD4 < 200 cells/mL. One hundred and sixty-one studies and 51,123 HIV-positive participants were included. The overall pooled prevalence of Cryptosporidium infection in HIV-positive patients was 11.2% (CI95%: 9.4%–13.0%). The pooled prevalence was estimated to be 10.0% (CI95%: 8.4%–11.8%) using staining methods, 13.5% (CI95%: 8.9%–19.8%) using molecular methods, and 26.3% (CI95%: 15.0%–42.0%) using antigen detection methods. The prevalence of Cryptosporidium in HIV patients was significantly associated with the country of study. Also, there were statistical differences between the diarrhea, CD4 < 200 cells/mL, and antiretroviral therapy risk factors with Cryptosporidiosis. Thus, Cryptosporidium is a common infection in HIV-positive patients, and safe water and hand-hygiene should be implemented to prevent cryptosporidiosis occurrence in these patients.

Abstract
Becoming armed with an appropriate strategy to isolate the minimum number of human papillomaviruses (HPV), regardless of DNA extraction method, can be a huge step in preventing false negative; it has a significant effect on the management and control of HPV infection among women's population. This study was conducted in Qom province, considering the risk factors associated with HPV. It was able to analyze genetic evolution in its genotypes and evaluated the limit of detection by a new diagnostic approach. Totally, 486 Pap smear samples were tested; then, the HPV DNA was developed by a semi-nested quantification PCR. Positive samples were sequenced and submitted to the GenBank (MG825048-MG825061). After alignment, phylogenetic and polymorphism analyses were performed on the sequenced samples with a number of GenBank sequences. The overall HPV prevalence among all women in Qom was 11.7%. HPV6 (43.24%) and HPV16 (6.75%) were the most frequent LR and HR genotypes, respectively. Although the Tajima's D of all genotypes was positive, it was negative individually. The position of genotypes 6, 11, and 73 was controversial on phylogenetic trees. Limit of detection (LOD) was obtained as about 10-100 copies per reaction in various genotypes of HPV by semi-nested qPCR. The nature of HPV could be preserved during natural selection. This research, through innovative usage of the primers, could detect different genotypes of the HPV, and inform the women society of the probable risk through its prevalence determination.

Abstract
Toxoplasmosis, one of the most common parasitic infections, can cause abortions in human. The purpose of this study was to determine seroprevalence of toxoplasmosis and acute form of toxoplasmosis in pregnant women. 208 pregnant women who referred to health centers in south-eastern Iran were taken under study after signing the informed consent forms and filling out the checklists. For those with high levels of IgG or IgM antibody titers, IgG Avidity test was performed to determine the acute infection. High level of IgG anti-body were found in sera of 81 pregnant women and 7 persons had borderline titer. IgM antibody results were positive in 33 and borderline in 4 cases. Then, the samples with positive and borderline results for IgM and IgG were evaluated by IgG avidity test. In this study, approximately 60% of pregnant women were not immune to risks posed by Toxoplasma gondii. Therefore, this group are at risk of acquiring primary infection of toxoplasmosis during gestation.

Abstract
Strongyloidiasis is caused by nematode infections of the genus Strongyloides, mainly Strongyloides stercoralis, and affects tens of millions of people around the world. S. stercoralis hyperinfection and disseminated strongyloidiasis are unusual but potentially fatal conditions mostly due to Gram-negative bacteremia and sepsis, primarily affecting immunocompromised patients. Infections with immunosuppressive viruses such as human immunodeficiency virus (HIV) and Human T-cell leucemia virus type 1 (HTLV-1) have been reported as risk factors for strongyloidiasis. Hyperinfection syndrome has been described in HIV-positive patients following the use of corticosteroids or during immune reconstitution inflammatory syndrome (IRIS). In this research, we conducted a global systematic review and meta-analysis to assess the seroprevalence and odds ratios (ORs) of S. stercoralis infections in HIV-infected patients. A total of 3,649 records were screened, 164 studies were selected and evaluated in more detail, and 94 studies were included in the meta-analysis. The overall pooled prevalence of S. stercoralis infection in HIV positive patients was 5.1% (CI95%: 4%-6.3%), and a meta-analysis on six studies showed that with a pooled OR of 1.79 (CI95%: 1.18%-2.69%) HIV-positive men are at a higher risk of S. stercoralis infections (p < .0052) compared to HIV positive women.

Abstract
Background Malaria transmission through blood transfusion is an accidental but preventable cause of malaria infection and is increasingly becoming a matter of concern for blood transfusion services. This systematic review was conducted to provide a summary of evidence about the prevalence of Plasmodium infection in asymptomatic blood donors and the effectiveness of screening methods used based on the available literature. Methods PRISMA guidelines were followed. Scopus, PubMed, Science Direct, and EMBASE were searched from 1982 to October 10, 2017. All peer-reviewed original research articles describing the prevalence of malaria parasitemia in blood donors with different diagnostic methods were included. The random-effects model was applied to assess the effects of heterogeneity among the selected studies. Incoherence and heterogeneity between studies were quantified by I2 index and Cochran’s Q test. Publication and population bias was assessed with funnel plots and Egger’s regression asymmetry test. All statistical analyses were performed using Stata (version 2.7.2). Results Seventy-one studies from 21 countries, 5 continents, were included in the present systematic review. The median prevalence of malaria parasitemia among 984 975 asymptomatic healthy blood donors was 10.54%, 5.36%, and 0.38% by microscopy, molecular methods (polymerase chain reaction), and rapid diagnostic tests, respectively. The most commonly detected Plasmodium species was P. falciparum. Conclusions This systematic review demonstrates that compared with other transfusion-linked infections, that is, HIV, HCV, and HBV, transfusion-transmitted malaria is one of the most significant transfusion-associated infections especially in Sub-Saharan Africa. Future work must aim to understand the clinical significance of transfusion-transmitted malaria in malaria-endemic settings.

Abstract
Over one-third of the world's population are seropositive for Toxoplasma gondii. One of the important traits of T. gondii is its ability to alter and manipulating the behavior and personality of its intermediate host. The current study was aimed to determine the prevalence of acute and chronic toxoplasmosis in those persons suffer from schizophrenia using serological and molecular techniques. In this cross-sectional study, blood samples were taken from 118 Schizophrenia patients hospitalized in Sistan and Baluchestan province, southeast of Iran. IgM and IgG anti-Toxoplasma antibodies were measured using enzyme-linked immunosorbent assay (ELISA). Furthermore, the presence of parasite was evaluated using nested-PCR B1 gene. Among 118 schizophrenic patients, 48 (40.67%), 4 (3.37%) and 14 (11.86%) were tested seropositive only for IgG, only for IgM and for both of IgG/IgM. So that, total prevalence was 66/118 (55.91%). All samples were also examined using nested-PCR and T. gondii DNA was found in 41 (34.74%) samples. Our study showed high seroprevalence of toxoplasmosis in southeast of Iran.

Abstract
BACKGROUND Malaria is still a major public health problem in subtropical and tropical regions. The rapid and accurate diagnosis of malaria remains a challenge in most of the endemic areas. The primary objective of the present study was to evaluate the performance of multiplex/nested PCR in detecting Plasmodium falciparum at low parasite densities and mixed infection. METHODS The study was performed in the Sistan-Baluchestan province of the southeastern Iran, from May 2015 to July 2016. A total of 105 patients suspected to malaria infection were enrolled in the study. The obtained DNA products, extracted from the thick/thin films, were analyzed by multiplex/nested PCR using genus-specific primers and compared with light microscopy. RESULTS 43 samples were confirmed to be infected by microscopic examination. Among 43 microscopically diagnosed P. falciparum cases, 11.4% (12/105) were confirmed by multiplex/nested PCR, 36.2% (38/105) were confirmed as P. vivax, 1.9% (2/105) had mixed infections with P. falciparum and P. vivax. Among microscopy-negative samples, 10 samples turned malaria-positive in nPCR. In multiplex/nested PCR, the rate of mixed infections was 8.6% (9/105). When compared to LM, the sensitivity, specificity, positive predictive value and negative predictive value of multiplex/nested PCR were calculated to be 82.8, 91.5, 92.3 and 81.1%, respectively. CONCLUSION In this study, we showed that microscopic examination of blood smears does not reliably distinguish Plasmodium species in the case of mixed infections. Therefore, it seems that multiplex/nested PCR is a good candidate for examining the presence of malaria parasites in clinically suspected but microscopically negative cases.

Abstract
OBJECTIVE The present investigation aims to evaluate the prevalence of IgM and IgG anti-T. gondii antibodies and the associated risk factors among healthy blood donors in Mashhad city, Razavi Khorasan province, Iran. METHODS We screened a total of 500 serum samples by census method from apparently healthy blood donors of the Mashhad Blood Transfusion Organization (MBTO) for IgG and IgM anti-T. gondii antibodies by enzyme linked immunosorbent assay (ELISA). RESULTS We found that 29.6%, 25%, 1.4%, and 3.2% of tested donors were positive for anti-T. gondii antibodies, only IgG antibody, both IgM and IgG, and IgM antibody alone, respectively. Several risk factors which were significantly related to T. gondii seropositivity in the univariate analysis at P < 0.05 included female gender (OR = 3.222, P < 0.001), age more than 40 years (P = 0.026), and sausage/hot dog consumption (OR = 4.472, P < 0.001). CONCLUSIONS The results of this study can be a warning for blood transfusion organizations to pay special attention to toxoplasmosis among blood donors and also design screening programs for prevention of transfusion-transmitted toxoplasmosis.

Abstract
Cutaneous leishmaniasis (CL) is vector borne parasitic disease, considered as public health problem especially in border of Iran and Iraq, Dehloran County (Musian district). The aim of this study was molecular identification of Leishmania parasites in sandfly as vectors of Leishmaniasis. Totally 280 female sandflies were trapped by sticky traps from 7 rural areas of Musiyan in September-November 2012. All sandflies were identified using morphological characters of the head and abdominal terminalia. DNA was extracted from female sandflies and Leishmania was identified using PCR and sequencing. All 280 trapped sandflies were identified as Phelobotumus Papatasi and Leishmania infections were detected in 3.2 % out of 280 female sandflies. All leishmania were identified as L. major and submitted in Gene bank as: LC014642.1, LC014641.1, LC014640.1 and LC014639.1. Frequency of Phlebotomus Papatasi and infection with L. major in studied regions showed that this vector is dominant in these areas.

Abstract
Reviews have shown increasing number of Iranian patients with cutaneous leishmaniasis (CL) who are unresponsive to pentavalent antimonial compounds such as meglumine antimoniate (Glucantime, MA). The present investigation aims to determine the correlation between clinical responses (healing, or non-healing) with susceptibility of Leishmania parasites to glucantime. Initially, in vitro susceptibility of Leishmania parasites was carried out on 93 isolates using macrophage models. Identification of these species was also performed by molecular methods including Nested-PCR and PCR-RFLP. The f indicated that total isolated were L. major. A significant association between the clinical outcome and the in vitro effective concentration 50% (EC50) values was observed. Leishmania derived from patients with non-healing lesions had EC50 values at least 3-fold higher than parasites isolated from lesions of healing patients. By molecular methods, patterns for both sensitive and resistant samples demonstrated restriction band which is related to L. major. The obtained findings in the present study demonstrated that MA-resistant L. major field isolates are now frequent in Iran. Such studies help to find strategies for rapidly diagnosing resistance in order to improve the clinical management of CL.

Abstract
BACKGROUND Scorpion sting is a public health problem in Khuzestan, South-West Iran. The aims of the current study were to monitor the hospitalized children, due to scorpion sting, and releasing more clinical and epidemiologic data related to scorpionism in this Province. METHODS In this retrospective study, the data of scorpion sting victims, among the hospitalized children in Abuzar Children Hospital of Ahvaz Jundi Shapur University of Medical Sciences, was analyzed from the points of epidemiological and clinical aspects in 2006. RESULTS The scorpion species of 18 files out of 57 were recognized accurately, using Farzanpay's keyof Iranian scorpions, as Androctonus crassicauda (Scorpionida: Buthidae) and Hemiscorpious lepturus (Scorpionida: Hemiscorpiidae). CONCLUSION The most scorpionism emergencies among the children in the Khuzestan should be paid to those species. However, H. lepturus sting emergencies are in the top of attention among the children.

Abstract
BACKGROUND Cutaneous leishmaniasis constitutes a major public health problem in many parts of the world including Iran. The primary objective of this study was to identify Leishmania species in endemic districts of Kerman Province, south-eastern Iran. METHODS This study was conducted by random sampling as cross- sectional descriptive between 2008 and 2010. Overall, 203 skin scraping smears were taken from the patients. Nested -PCR was performed to amplify variable minicircle fragments of Leishmania kDNA. RESULTS Bam was the most infected district (71.1%), followed by Kerman (14.7%), Jiroft (5.4%), Baft (2.7%), Sirjan (1.6%), Shahr-e Babak (1.5%) and others (3.0%). L. tropica was the most common species identified (194 cases, 95.6%), while L. major was found in only 9 cases (4.4%). Of 203 identified patients, all species in Bam (l07 cases), Kerman (32 cases), Jiroft (l6 cases) and Shahr-e- Babak (l1 cases) were detected as L. tropica, whereas infected subjects in Baft and Sirjan showed L. tropica or L. major. Characterization of Leishmania species resulted in generation of 750 bp and 560 bp fragments, corresponding to those of L. tropica and L. major, respectively. CONCLUSION L. tropica is the main species (95.6%) caused ACL in endemic areas of Kerman Province; however L. major is present in low level (4.4%).

Abstract
BACKGROUND Visceral leishmaniasis (kala-azar) is an endemic disease in some areas of Iran. A cross- sectional study was conducted for sero-epidemiological survey of visceral leishmaniasis (VL) in Baft district from Kerman Province, southeast of Iran. METHODS Blood samples were collected from children up to 12 years old and 10% of adult population from Baft villages with a multi-stage randomized cluster sampling. In addition, blood samples were collected from 30 domestic dogs from the same areas. All the collected blood samples were tested by direct agglutination test (DAT) for the detection of anti-Leishmania antibodies in both human and dog using the cut-off value of ≥1:3200 and ≥1:320, respectively. Parasitological, molecular, and pathological were performed on infected dogs. Chi-square and Fisher exact tests were used to compare sero-prevalence values. RESULTS From 1476 collected human serum samples, 23 (1.55%) showed anti-Leishmania antibodies at titers of 1:800 and 1:1600 whereas 14 (0.95%) showed anti-Leishmania infantum antibodies at titers of ≥1:3200. No statistically significant difference was found between male (1.18%) and female (0.69%) sero-prevalence (P=0.330). Children of 5-8 years showed the highest sero-prevalence rate (3.22%). Seven out of 30 domestic dogs (23%) showed anti-Leishmania antibodies at titers ≥1:320. Leishmania infantum was identified in five infected dogs by nested - PCR assay. CONCLUSION It seems that visceral leishmaniasis is being endemic in southern villages of Baft district, southeast of Iran.
