Methods: Eighty-five intestine samples from dead or shot wild canids, 59 fecal samples from sheepdogs and 5 from red foxes were collected from 2006 to 2008 and examined in Parasitology department of Pasteur Institute of Iran. Results: Generally, adult worms, larvae, and eggs of 13 species of various parasitic hel­minths were recovered. Necropsy examinations showed that 96.47% animals harbored at least one helminth species. The prevalence of different species in necropsy were Mesoces­toides sp. 84.7%, Rictolaria spp. 55.3%, Macranthorhynchus hirudinaceus 45.9%, Toxocara canis 43.5%, Toxas­caris spp. 35.3%, Joyeuxiella sp. 34.1%; hook­worms; 22.4%, Taenia spp. 11.8%, Alaria spp. 2.4% and Dipylidium caninum 1.2%. Be­sides, eggs belonging to 10 species of parasitic helminths were identified in 46 fecal sam­ples and generally, 30.9% of samples harbored eggs of at least one helminth species. Conclusion: The high prevalence of various helminth infections among canids in Mog­han plain and contamination of environment by helminths eggs may increase the risk of infection for native peo­ple. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/134 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/134/133
