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.
