More than 30 species of exotic ungulates are currently kept in the Askania-Nova Biosphere Reserve (Kherson Region, Ukraine). During the years 1978–2014, 146 ungulates of 24 species (16 species of Bovidae, 4 — Cervidae, 4 — Camelidae) were examined by partial helminthological dissection; more than 402,700 specimens of helminths were collected and identified. The purpose of the present study was to summarize these data and analyze the species diversity in exotic ungulates. Totally, 38 species of helminths: 3 species of Trematoda, 6 — Cestoda, 29 — Nematoda were found. Ungulates from the family Bovidae were the most infected; they harbored 36 species of helminths, 1–18 species per host. In Camelidae, 15 species were found; 3–10 species per host. Cervidae harbored 9 species; 1–6 species per host. The highest species diversity was detected in the ungulates introduced from regions with climatic conditions similar to those in southern Ukraine: saiga antelope (19 species), European mouflon (18), Barbary sheep (18), and markhor (17). Ten species typical for domestic ruminants (Haemonchus contortus, Nematodirus sp., Aonchotheca bovis, Moniezia expansa, Oesophagostomum venulosum, Ostertagia circumcincta, Trichostrongylus axei, T. colubriformis, T. probolurus and Trichuris ovis) dominated in the parasite communities. Our results indicated reduction in the species diversity and alteration of the parasite community structures in these exotic ungulates kept in the Askania-Nova Reserve compared to their natural habitats.
