Background and purpose: India and Iran are an important endemic focus of cystic hydatid disease (CHD), where several species of intermediate host are commonly infected with Echinococcus granulosus. Strain characterization of E. granulosus is significant for the development of an effective control programme and to asses the infectivity. In present study, genetic variations in tapeworms causing...
Background: Direct identification of Leishmania species in Giemsa-stained slides without parasite culturing in the areas where multiple species exist, is very helpful. This study was designed to isolate Leishmani spp. from Giemsa-stained smears and to characterize them by PCR technique. Methods: A total of 48 Giemsa-Stained slides from confirmed cases of leishmaniasis were examined under a ligh...
سابقه و هدف: امروزه به منظور بررسی تفاوت های درون گونه ای و نژادی از روش rflp ناحیه igs استفاده می شود. این مطالعه با هدف شناسایی گونه های بیماری زای آلترناریا عامل تولید لکه برگی مرکبات با استفاده از روش های مورفولوژیک و توالی یابی ناحیه its1 در شهرستان ممسنی و نیز بررسی تفاوت های ژنتیکی جدایه های این قارچ بر اساس rflp ناحیه igs انجام گردید. مواد و روش ها: این پژوهش به صورت مقطعی- توصیفی بر ...
زمینه و هدف: با توجه به وجود 10 ژنوتیپ مختلف از انگل اکینوکوکوس گرانولوزوس با میزبان‌های واسطه و نهایی مختلف و اثرگذاری این ژنوتیپ‌ها در چرخه زندگی انگل و انتقال آن به انسان، هدف این مطالعه تعیین خصوصیات مولکولی جدایه‌های کیست‌های هیداتید و انتشار آنها در کبد و ریه دام‌های کشتار شده در کشتارگاه صنعتی شهر یاسوج بود. روش بررسی: در این مطالعه تجربی تعداد 93 کیست هیداتید دامی(31 نمونه گوسفند، 5...
Background & Objectives: This study aimed to determine of the seroprevalence of visceral leishmaniasis to design a prevention and control program in Bojnoord district. Methods: This was a descriptive and cross sectional study with multistage random sampling method. The study was carried out on children up to 12 years old and 10% of adult’s population in 8 rural areas of Bojnoord district in ...
Anisakis spp. (Nematoda: Anisakidae) parasitize a wide range of marine animals, mammals serving as the definitive host and different fish species as intermediate or paratenic hosts. In this study, 18 fish species were investigated for Anisakis infection. Katsuwonus pelamis, Euthynnus affinis, Caranx sp., and Auxis thazard were infected with high prevalence of Anisakis type I, while Cephalopholi...
BACKGROUND In the northeast and central parts of Iran, Rhombomys opimus (great gerbil) is the primary reservoir host of zoonotic cutaneous leishmaniasis (ZCL). This study used both parasitological and molecular methods to identify Leishmania spp. and their different haplotypes that were circulating in the great gerbil populations in ZCL foci from northeastern Iran. METHODS A cross-sectional s...
Explaining cases of long-term persistence of parthenogenesis has proven an arduous task for evolutionary biologists. Interpreting sexual-asexual interactions though has recently advanced owing to methodological design, increased taxon sampling and choice of model organisms. We inferred the phylogeny of Artemia, a halophilic branchiopod genus of sexual and parthenogenetic forms with cosmopolitan...
Diagnosis of the endemic cutaneous leishmaniasis (CL) in Jordan relies on patient clinical presentation and microscopic identification. Studies toward improved identification of the causative Leishmania species, especially in regions where multiple species exist, and the introduction of these techniques into medical diagnosis is paramount. This study looked at the current epidemiology of CL in ...
