| Parasitological monitoring in the European Bison (Bison bonasus) Breeding Center of Bialowieza National Park |
| Parasite invasions are one of the main diagnosed pathologies of European bison. Since the severity and parasite species composition varies depending on the season, parasitological monitoring and deworming of European bison and evaluation of its effectiveness is important in the breeding of European bison. For that reason, parasi-tological evaluation based on coproscopical methods of live animals was performed. Full parasitological exam-inations of the digestive system together with necropsies were performed post-mortally. The obtained data ena-bled the selection of a suitable deworming treatment. The results showed that the parasite species composition in the fenced European bison breeding center was similar to the situation observed in free ranging European bison. The invasion of a blood sucking nematode Ashworthius sidemi was confirmed in European bison closed breed-ing for the first time. None of the European bison showed any clinical symptoms caused by parasitic factors. The research proved that from the clinical point of view the deworming process is more crucial in the spring, because of increased intensity and extensiveness of invasions during this time and the possibility for the use of chemotherapeutics with a broader spectrum of treatment. |
