A Comparison of the Prevalence of Gastrointestinal Parasites in Wild Boar ( Sus scrofa L.) Foraging in Urban and Suburban Areas.

The aim of this study was to compare the species composition of gastrointestinal parasites in wild boar feeding in the city of Szczecin with those in its suburban area, as well as to determine the prevalence and intensity of this parasite infection. The intestines and stomachs of 57 wild boars were supplied by a municipal hunter from the city of Szczecin. Both analysed groups of animals were infected with the following parasites: Eimeria debliecki , E. suis , E. polita , E. scabra, Isospora suis , Ascaris suum and Oesophagostomum dentatum . Wild boar from the city were characterised as having a significantly higher prevalence of total Eimeria ( p = 0.04) and a lower prevalence of noted species of nematodes ( p = 0.15) compared to those from the suburban area. Since the wild boars were mainly infected with Eimeria , it should be assumed that they may pose a real health threat to farm pigs and other farm animals for which Eimeria is a pathogenic parasite. The occurrence of coccidiosis leads to serious health problems and economic losses for breeders. Although the prevalence of A. suum was low, it should be taken into account that this nematode is able to both infect and complete their life cycle in humans.
