摘要: 通过采集甘孜州气候、生态环境迥异的半农半牧区康定县和纯牧区色达县不同乡镇的共计500头份牦牛粪样,对牦牛球虫感染情况进行调查:球虫平均感染率为30.00%(150/500),其中康定县的平均感染率为31.95%(54/169),色达县的平均感染率为29.00%(96/331);公牛粪样球虫阳性率为26.38%(43/163),母牛粪样球虫阳性率为31.75%(107/337);成年牛(3岁以上)粪样球虫阳性率为16.22%(42/259),犊牛及青年牛(3岁以下)粪样球虫阳性率为44.81%(108/241);从牦牛感染球虫的种类来看,单一感染(62/150)小于混合感染(88/150);共检出9种球虫,分别为牛艾美耳球虫(24.00%)、柱状艾美耳球虫(12.00%)、邱氏艾美耳球虫(16.00%)、亚球形艾美耳球虫(18.03%)、巴西艾美耳球虫(8.27%)、加拿大艾美耳球虫(6.67%)、椭圆艾美耳球虫(9.33%)、怀俄明艾美耳球虫(3.30%)和奥博艾美耳球虫(2.40%)。

Abstract: 500 fecal samples of Yak in Kangding and Seda county were collected for epidemiological investigation of yak coccidiosis. Coccidia mean infection rate was 30.00%(150/500),Kangding and Seda county were 31.95%(54/169) and 29%(96/331) respectively. Male yak mean infection rate was 26.38%(43/163),female yak was 31.75%(107/337). The infection rate of adult dairy yak (>3 years old)was 16.22%(42/259),young and calves dairy yak(<3 years old)was 44.81%(108/241). Nine species of Eimeria coccidian were identified as follows: Eimeria bovis (24.00%),E.cylindrica(12.00%),E.zurnii(16.00%),E.subspherica(18.03%),E.brasilicnsis(8.27%),E.canadensis(6.67%),E.ellipsoidallis(9.33%),E.wyomingensis(3.30%) and E.auburncnsis(2.40%).
