Molecular analysis of lungworms from European bison (Bison bonasus) on the basis of small subunit ribosomal RNA gene (SSU)

Dictyocaulosis (Nematoda: Trichostrongyloidea) is a widespread parasitosis of the European bison (Bison bonasus) inhabiting Bialowieza Primeval Forest. Bearing in mind the current coexistence of bison with wild cervids, and with domestic ruminants in the 19th and 20th century, the need arose for molecular identification of lungworm species. Molecular analysis was done on adult lungworms that were obtained from the respiratory track of four free-roaming bison euthanized as a part of the population health control program. As the result of the study four identical small subunit-ribosomal RNA gene sequences from the lungworms were obtained and deposited in GenBank as sequence, 1708 bp long (GenBank KC771250). Comparative analysis of the SSU rRNA sequences revealed the European bison to be a host for the bovine lungworm Dictyocaulus viviparus.

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, parasitological evaluation based on coproscopical methods of live animals was performed. Full parasitological examinations of the digestive system together with necropsies were performed post-mortally. The obtained data enabled 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 breeding 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.
