Gastrointestinal Nematodes in Moufflons and Domestic Sheep in Protected Areas of Uzbekistan

Abstract

The article studied gastrointestinal nematodes in moufflons and domestic sheep in protected areas of Uzbekistan. Twenty-two nematode species were identified in the digestive tract of moufflons and domestic sheep including 21 species in domestic sheep, 7 in Severtsev’s sheep, 5 in Ustyurt mountain sheep, and 2 in Bokharan mountain sheep. Moreover, the family Trichostrongylidae includes 11 nematode species; Molineidae, 3 species; Trichinellidae, Strongylidae and Ancylostomatidae, 2 species each; and Onchocercidae, Gongylonematidae and Habronematidae, one species each. Nematodes of the species Setaria labiatopapillosa, Gongylonema pulchrum, Parabronema skrjabini are considered biohelminths, they develop with participation of beetles (Scarabiidae and Tenebrionidae fam.) and blood-sucking insects (Haematobia gen.); the rest species are geohelminths. It should be noted that the species Marshallagia marshalli and Teladosagia circumcincta were recorded in all animals studied; G. pulchrum and P. skrjabini in domestic sheep, Ustyurt mountain sheep and Severtsev’s sheep; Nematodirus abnormalis and N. helvetianis in domestic sheep and Severtsev’s sheep; and N. oiratianus in domestic sheep and Ustyurt mountain sheep.
