Ecological and Faunistic Studies of Wild Artiodactyl Helminths (Mammalia: Artiodactyla) of Karakalpakstan

Abstract

We found that the types of Artiodactyla in the biogeocenozak of Karakalpakstan are represented by 5 species: Sus scrofa nigripes Blan., Cervis elaphus bactrianus Lydek., Gazella subgutturosa Gueld., Saiga tatarica Linn., Ovis orientalis arcal Gmel. and in which 26 species of helminths that belong to the classes of Cestoda, Trematoda and Nematoda have been identified. Cestodes are represented by 6 species, trematodes - 2 and nematodes - 18. The species composition of the helminths of the studied animals is 14 species in pigs, 11 in Bukhara deer, 13 in saigas, and 14 in gazelles. The helminthes, common to these species of animals, are types of the genera Taenia, Echinococcus, Fasciola, Schistosoma, Gongylonema and Setaria.

By the nature of the biological cycle, the helminths recorded by us can be divided into two groups: monoxenic and heteroxenic. Monoxenic species include types of the families Trichosephalidae (three species), Trichostrongylidae (2 species), Dictyocaulidae (2 species), Syphaciidae (1 species), Ascarididae (1 species), life cycles that proceed without a change of owners. The development of 18 species of cestodes (6 species), trematodes (2 species) and nematodes (10 species) representatives are carried out with the obligatory participation of intermediate hosts.
