Distribution and fertility of <i>E chinococcus granulosus</i> larvocyst in sheep from North Caucasus
Distribution and fertility of Echinococcus granulosus cysts in sheep of different breeds in North Caucasus are studied. Sheep of North Caucasian breed were infected with E. granulosus at 23,6 %, the Karachay, Stavropol, Lezghin and Andi breeds respectively on 18,2; 30,3; 26,4 and 21,7 % at intensity of infection 16,0±2,5 sp./goal., 14,2±2,4, 22,3±2,7, 20,4±2,6 and 18,1±2,5 sp./goal. Sheep strain of E. granulosus constitutes epizootologic danger as is in 100 % cases fertile. It is contains in 1 ml of E. granulosus liquid 102,3±6,5-128,2±8,6 sp. of E. granulosus protoskolex. The maximum contamination is established by cysts of E. granulosus in sheep of Stavropol breed, the smallest - at sheep of Karachay breed.
