The influence of biocenosis on the formation of parasitofauna in the northern tien shan

In the Karkary-Kegen valley of the Almaty region of Kazakhstan, when breeding a new breed of sheep with the participation of different animal species, their parasitofauna was formed from parasites present in this biocenosis or natural focus. In this region there were 75 species of parasites belonging to 5 types, 5 classes, 3 subclasses, 3 orders, 10 suborders, 4 superfamilies, 21 families, 11 subfamilies, 1 tribe and 34 genera. During the formation of the breed for more than 20 years, archaromerinos had 28 species of parasites: one species of trematodes (D.lanceatum,), 4 species of cestodes (T.hydatigena, larvae; E.granulosa,larvae; M.expansa; M.benedeni) and 23 species of nematodes (S.ovis, Ch.ovina, T.axei, T.colubriformis, O.circumcincta, O.occidentalis, O.trifida, O.trifurcata, M.marshalli, N.archari, N.dogieli, N.filicollis, N.oiratianus, N.spathiger, N.longissimespiculata, D.filaria, P.davtiani, P.hobmaieri, P.raillieti,P.skrjabini, C.nigrescens, B.schulzi, T.skrjabini). In the next 60 years, hybrids acquired another 35 species. Thus, a new breed of animals is included in the cycle of invasion in the biocenosis. Some parasites (not previously noted in this biocenosis) that are in the body of archaromerinos, getting into the external environment with feces, form new foci, involving other species of animals living in this biocenosis in the circulation.
