摘　　要：对新疆南疆4个行政区6个品种的434份绵羊血清,采用双抗原夹心酶联免疫法检测抗戊型肝炎病毒(HEV)IgG抗体,比较不同地区、不同品种及不同年龄段绵羊戊型肝炎抗体阳性率的差异。结果显示,所检测血清总的抗体阳性率为32.25%(140/434),4个地区绵羊抗体阳性率依次为32.34%(65/201),37.25%(19/51),47.25%(43/91),14.29%(13/91),差异极显著(p<0.01);2岁以上绵羊与1岁以下绵羊抗体阳性率依次为47.25%(43/91)和21%(25/121),差异极显著(p<0.01);不同品种绵羊HEV感染率差异显著(p<0.05)。由此可见,新疆南疆地区绵羊普遍存在HEV感染。Four hundreds and thirty four serum samples from-6 sheep breeds at 4 administrative areas in Xinjiang were detected by ELISA for the presence of IgG antibodies against hepatitis E virus （HEV）, and analysed by Chi-square Test based on geo-locations, breeds and age groups. Significant differences were detected among 4 administrative areas （p〈0.01） with an average positive rate of 32.25 % （140/434）. There was a visible difference between age groups, with 47.25 % （43/91） positive among 2 years old or over, and 21% （25/121） below 1 year old. The sero-prevalence appeared related to breeds. These data confirmed that sheep HEV was widespread in Nanjiang of Xinjiang.
