2015年西藏地区牦牛流行热病血清流行病学调查

Seroprevalence Investigation of Bovine Ephemeral Fever in Yaks from Tibetan region of 2015

为调查牛流行热病在西藏地区牦牛群体中的流行情况,本试验应用双抗原夹心ELISA对2015年采自西藏地区的206份犊牦牛、成年牦牛血清进行牛流行热抗体检测。结果显示,49份血清呈牛流行热抗体阳性,总阳性率为23.8%(49/206),其中成年牦牛血清总阳性率为39.3%(44/112),成年母牦牛血清阳性率为46.2%(36/78),成年公牦牛血清阳性率为23.5%(8/34);犊牦牛血清总阳性率5.3%(5/94),母犊牦牛血清阳性率为9.3%(4/43),公犊牦牛血清阳性率为1.9%(1/51)。结果表明,西藏地区牦牛存在牛流行热病毒的感染,且年龄、性别与该病的发生有重要的关系。

To investigate the popularity of Bovine ephemeral fever in yak groups from Tibetan region,we used Enzymes linked immunosorbent assay to practice the Bovine ephemeral fever antibody test which used 206 serum samples collected from mature yaks and immature yaks.The test detected 49 positive serum samples among all the samples.The total morbidity in mature yaks is 39.3%（44/112）. Among the mature yaks, morbidity of mature female yaks is 46.2%（36/78）,and morbidity of mature male yaks is 23.5%（8/34）.The total morbidity in immature yaks is 5.3%（5/94）.Among the immature yaks,morbidity of immature female yaks is 9.3%（4/43）, and morbidity of immature male yaks is 1.9%（1/51）.It suggested that Bovine ephemeral fever disease do exists in Tibetan region,while age and gender of yaks are related to developing of the disease.
