Pestechian, NaderKalani, HamedFaridnia, RoghiyehYousefi, Hosein-Ali

Background: The most important genera of trichostrongylid nematodes that live in digestive tract of ruminants include Teladorsagia, Haemonchus, Trichostrongylus, Cooperia and Marshallagia. Out of the above-mentioned genera, four infect humans including Teladorsagia, Haemonchus, Trichostrongylus and Marshallagia. These parasites are an important part of ruminant pathogens, and some are extremely pathogenic and deadly, and thus vitally important from veterinary viewpoint. Hence, this study was performed to determine the latest status of zoonotic gastrointestinal trichostrongylid nematodes in sheep and goat, in Isfahan province, center of Iran.Materials, Methods & Results: The intestines and abomasums of 109 small domestic ruminants (56 sheep and 53 goats) which were slaughtered at Isfahan slaughterhouses were collected and placed separately in large containers to be transferred to the laboratory. To investigate morphological characteristics, the found nematodes were placed on glass slides appropriately, dyed by lactophenol and azocarmine as a temporary mount. Finally, their genus and species were identified according to morphological characteristics using valid taxonomic keys. Seven species of trichostrongylid nematodes belonged to four genera were isolated from intestines and abomasums of sheep and goats. The found species were Trichostrongylus vitrinus, T. probulurus, T. co
