Ovine parasites in the Zailiyskiy Alatau.

Abstract

The materials of research in the Zailiyskiy Alatau are presented for parasitosis monitoring of crossbred sheep in the Enbekshikazakhsky District of the Almaty Region, the Republic of Kazakhstan. Twenty two parasite species are parasitizing in crossbred sheep in the Zailiyskiy Alatau: 6 protozoa species (Eimeria faurei, Eimeria intricata, Eimeria ovina, Eimeria ovinoidalis, Eimeria parva and Sarcocystis ovicanis), 4 trematode species (Fasciola hepatica, Dicrocoelium lanceatum, Eurytrema pancreaticum and Hasstilesia ovis), 2 cestode species (Moniezia expansa and Moniezia benedeni) and 10 nematode species (Trichostrongylus axei, Ostertagiella circumcincta, Ostertagiella trifida, Ostertagiella trifurcata, Marshallagia marshalli, Haemonchus contortus, Nematodirus oiratianus, Nematodirus spathiger, Strongyloides papillosu and Trichocephalus skrjabini). The total infection of the crossbred sheep with Eimeria was 30%; Anoplocephalids, 30%; Haemonchus, 10%; Nematodirus, 20%; and Strongyloides, 20%. Eimeria monoinvasion occurs in 10%, and Anoplocephalid and Strongyloide monoinvasion, in 5% of cases. Mixed invasions of Eimeria + Anoplocephalids occur in 10% of sheep, Eimeria + Anoplocephalids + Strongyloides, Eimeria + Haemonhus + Nematodirus, Eimeria + Nematodirus + Strongyloides, Eimeria + Strongyloides, and Haemonhusa + Nematodirus, in 5% of sheep. Protozoa and helminths occur in sheep both as a monoinvasion and mixed invasions in the Zailiyskiy Alatau.
