Abstract：The purpose of this study was to investigate the infection of Echinococcus granulosus among Kazakh sheep in Yili Valley,in order to provide reference for the prevention and control of echinococcosis granulosa and the healthy development of Kazakh sheep breeding industry.A total of 166 liver tissues from slaughtered Kazakh sheep in four counties and cities'designated slaughterhouses in the Yili Valley were collected to determine the infection status of Echinococcus granulosus.In addition,the double-antibody sandwich ELISA method was used to test the feces of 142 local Kazakh sheep farmers'dogs.Results show that the echinococcosis granulosa positive rate of Kazakh sheep in Yili Valley was 4.22%(7/166).Yining City,Yining County,Qapqal Xibe Autonomous County,and Gongliu County positive rate was 2.78%(2/72),5.71%(2/35),3.33%(1/30),6.90%(2/29).Dog feces antigen positive rate was 3.52%(5/142).Yining City,Yining County,Qapqal Xibe Autonomous County,and Gongliu County positive rate was 4.88%(2/41),2.86%(1/35),2.94%(1/34),3.13%(1/32).The study showed that the infection of Echinococcus granulosus of Kazakh sheep in Yili Valley showed a downward trend,but the purification effect was still not reached.Attention should be paid to the cyclic transmission of the disease between sheep and dogs,and the transmission of the disease should be controlled by strengthening publicity and education,strengthening dog management,implementing regular monitoring and promoting scientific grazing.
