Background: The detection of Fasciola species in various geographical regions is essential for health policymaking. Here, we aimed to identify livestock (cattle and sheep) related Fasciola genotypes by restriction fragment length polymorphism PCR. Methods: Seventy adult Fasciola flukes were collected from 70 infected livers of 35 cattle and 35 sheep slaughtered in Zabol abattoir, outh-east Iran (Jan-Jul 2017). Fasciola species were determined based on molecular features. For molecular detection, Fasciola ITS1 region was amplified and sequenced. A 700 bp fragment was amplified. These were digested with RasΙ enzyme. F. hepatica specific fragments were 47, 59, 68, 104, and 370, while those related to F. gigantica had 45, 55, 170, 370. Results: The two main species of F. hepatica and F. gigantica are responsible for fasciolosis in sheep and cattle in our region. From 35 Fasciola isolated from cattle, 3 and 32 were F. hepatica and F. giagantica respectively. From 35 Fasciola isolated from sheep, 4 were F. hepatica and 31 were F. gigantica. Conclusion: All Seventy Fasciola samples from two different hosts (cattle and sheep) were identified as either F. hepatica or F. gigantica by PCR-RFLP. Genotypic variability of Fasciola species was high in our region. It is recommended to assess molecular variation of Fasciola isolates in other host livestock.

Objective: Sarcocystis spp. are common parasites and in terms of economics and pathogenicity in domestic animals is important. The purpose of this work was to define the rate of contamination of slaughtered carcasses of cattle to Sarcocystis using digestive and histopathological methods in southeast Iran. Material and Methods: In this descriptive laboratory study for 1 year, 500 carcasses were examined and isolated bradyzoites of Sarcocystis with the digest method. Also, tissue samples from the esophagus and diaphragm were considered for pathologic studies and stained with hematoxylin and eosin of sections of histopathological. Results: The results showed that the highest contaminations were in imported male animals aged 2–3 years old in the spring. There was a significant difference ( p < 0.05) in the prevalence rate with the sex and race of cattle but no significant difference ( p > 0.05) in the prevalence rate with age and season. Conclusion: Infection with Sarcocystis is common in oxen in this region. The imported cattle are more infected. It seems that racing and the environmental condition affect the prevalence of Sarcocystosis.

Native poultry is among the most important sources of meat and protein supply in Iran that has long been bred in various regions. Internal and external parasites are the main reasons for their reduced growth and production. is a cystic mite that is mostly found in the subcutaneous layer and surface of muscles of several birds. It can rarely cause lesions in other organs such as abdomen, lungs and peritoneum. The life cycle of has not been known completely yet, but after hatchery, the whole life cycle would be passed in the subcutaneous layer or on muscles. In the present study, 400 pieces of native chicken in the north Sistan-Baluchestan and Kerman provinces are monitored over 3 years for infestation with mites and its prevalence is determined (2.75%). Considering the infestation with this parasite in the southeast of the country (and probably in the remaining poultry), spraying and disinfection of chicken runs are recommended. This is the first report on the prevalence of this parasite in Iran.

Background: Toxoplasma gondii (T. gondii) causes an important parasitic infection known as toxoplasmosis, which is a globally distributed important zoonosis. One of the major serious characteristics of T. gondii is its ability to manipulate the behavior of intermediate hosts. We performed a cross-sectional study to determine toxoplasmosis in schizophrenic patients, as one of the major neuropsychiatric disorders, using loop-mediated isothermal amplification (LAMP) technic by targeting parasite B1 gene. Methods: Blood samples were taken from 118 schizophrenic patients hospitalized in tow hospitals including Baharan, Clinic of Psychiatric Ali-ibn-Abi-Talib Hospital (in Zahedan City), and Amir-al Momenin Psychiatric Hospital (in Zabol City), Sistan and Baluchestan Province, southeast Iran in 2016. They were analyzed using LAMP, and compared with the previous data of nested-PCR and serology. Results: Out of the 118 schizophrenic individuals, 56 patients (47.4%) were found to be infected with T. gondii. The diagnosis of toxoplasmosis was confirmed in 41 patients (34.7%) via the nested-PCR. The seroprevalence of toxoplasmosis in schizophrenic patients was 55.9% (66/118). Conclusion: We found a high efficiency of LAMP method in identifying toxoplasmosis and its high prevalence among schizophrenic patients. Our findings could provide viable offer implications for the prevention of schizophrenia.
