The current study aimed to assess the prevalence of helminth infections in wild boars in the Persian Gulf coastal area (Bushehr Province), Southwestern Iran. Methods: Twenty-five wild boars, including 11 males and 14 females, were collected during a course of vertebrate pest control in the Bushehr Province, southwestern Iran in 2013. The specimen were immediately dissected and carefully searched for the parasites. During necropsy, each organ was examined macroscopically for presence of any helminthic agents. Tissue samples were taken from each organ. Moreover, samples were taken from the content of digestive system. Blood samples were also collected from each boar. All the samples were evaluated for helminth infections by parasitological methods. Results: Twenty-two (88%) of the wild boars were infected with at least one helminth. Out of 25 wild boars, 1 (4%) were infected with Cysticercus tenuicollis, the larval stage of Taenia hydatigena, 13 (52%) with Macracanthorhynchus hirudinaceus, 17 (68%) with Metastrongylus spp, and 20 (80%) with Ascarops spp. Hydatid cyst was detected in the lung of one of the wild boars. No Trichinella spp. larvae were detected in any of the tissues of the animals when evaluated by artificial digestion method. In addition, no contamination with microfilaria was detected in any of animals when the blood samples were tested with Knott’s method. Conclusion: Wild boars are contaminated by some helminthes including zoonotic ones. These animals could be involved in the epidemiology of zoonotic helminth by acting as reservoir hosts. This in turn may bring potential risk for locals and residents of the Bushehr Province, Southwestern Iran. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/1209 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/1209/718
