【摘要】 采集新疆6个地区4个品种绵羊的826份血清(南疆348份、北疆478份),应用双抗原夹心酶联免疫法(DS-ELISA)检测抗戊型肝炎病毒(HEV)IgG抗体,比较不同地域、不同年龄以及不同品种绵羊HEV抗体阳性率的差异。结果显示,所检测羊血清中HEV抗体阳性率为19.13%(158/826),南、北疆羊HEV抗体阳性率分别为21.26%(74/348)和17.58%(84/478),差异显著(P<0.05)。卡拉库尔羊、小尾寒羊HEV抗体阳性率分别为23.94%(79/330)和17.33%(65/375),差异显著(P<0.05)。3岁以上、2～3岁和1岁以内羊的HEV抗体阳性率差异不显著(P>0.05)。这表明新疆地区绵羊HEV感染普遍存在。更多还原

【Abstract】 Eight hundred and twenty six sheep sera from 4 species raised at 6 regions of Xinjiang(348 from Southern Xinjiang,478 from Northern Xinjiang) were tested by DS-ELISA for the presence of anti-HEV IgG,and the prevalence differences were analysed based on location(South and North Xinjiang),age range(≤1year,2-3years,≥3 years) and species of sheep by χ2 test.The result showed the overall prevalence of anti-HEV IgG was 19.13%(158/826),but 21.26%(74/348) for the South Xinjiang,and significantly higher(P<O.05) than that of the North(17.58%(84/478)).The prevalence rate of Xinjiang native Karakuer sheep(23.94%(79/330)) was significantly higher(P<0.05) than that of the introduced little tailed Han sheep(17.33%(65/375)).No significant prevalence differences(P>0.05)were found between the analysed age ranges.更多还原
