The Balkans is endemic for nematodes of the genus Trichinella in both domestic and wild animals. The high prevalence of these zoonotic pathogens in animals linked with the food habits to consume raw meat and meat derived products resulted in a very high prevalence of trichinellosis in humans living in this European region. In spite of numerous epidemiological investigations carried out in this region, very few information is available on the Trichinella species circulating in Bosnia and Herzegovina. Trichinella spp. larvae were isolated from a domestic pig reared in a backyard and from a hunted wild boar whose meat had been the source of trichinellosis in one case. Both Trichinella pseudospiralis and T. spiralis have been identified in the domestic pig, whereas, T. britovi was detected in the wild boar. While, T. spiralis is the Trichinella species most frequently detected in domestic pigs, T. pseudospiralis has been previously documented in domestic pigs only three times in Russia, Slovakia and Croatia. The detection of T. britovi in the wild boar confirms that this nematode is the most frequent species circulating among wildlife of Europe.
