Stray dogs and wild candies can represent potential reservoirs of enteropathogens to other hosts. Therefore, present study determined the prevalence of intestinal parasites in canine in Mazandaran Province, northern, Iran. Methods: Overall, 58 small intestinal samples of animals (42 stray dogs and 16 jackals) were collected from Oct 2012 to Dec 2013. The intestine contents were studied to detect and identify helminth infections. Then, the helminths were collected and their morphological traits were identified. Results: Overall among infected stray dogs and jackals, 11 species were found. Three species of nematodes, seven species of cestodes and one trematode were observed. The prevalence of gastrointestinal helminths of stray dogs and jackals were 59.5% and 50%, respectively. Among registered zoonotic helminths A. caninum was the predominant parasite both stray dogs and jackals. Interestingly, Spirometra spp. was reported in these animals. Moreover, A. caninum showed a higher percentage rate in center region of province. Conclusion: There are the clear risks of zoonotic helminths parasites infection in this region. Therefore, understanding the epidemiology of zoonotic parasite infection is useful for health care access both domestic animals and humans health. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/2208 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/2208/833
