【摘要】 目的　探讨猪、羊、鸡群中抗 HEV抗体流行率。方法　从新疆、广西、广东、北京和河北收集猪、羊、鸡的血清标本 4 98份 ,应用双抗原夹心酶联免疫法 (ELISA)检测抗 HEV抗体。结果　猪抗 HEV阳性率为 6 7 5 3% (10 4 15 4 ) ,其中新疆 4～ 5个月龄猪血清抗 HEV阳性率为 10 0 0 0 % ,广西 3个月龄以下仔猪抗 HEV阳性率为 36 0 0 % (9 2 5 ) ,6月龄以上猪阳性率为 71 6 7% (86 12 0 ) ;新疆 10 8份绵羊血清抗 HEV抗体全部阴性 ;2 36份鸡血清标本的抗 HEV阳性率仅为 1 2 7% (3 2 36 )。广东罗定、深圳和广西柳州郊区鸡血清标本中各检测出一份抗 HEV阳性 ,阳性率分别为 4 0 0 % (1 2 5 )、1 4 9% (1 6 7)、1 4 9% (1 6 7)。北京郊区 2 5份和河北 5 2份鸡血清抗 HEV检测全部阴性。结论　猪、鸡群中存在HEV感染 ,猪抗 HEV抗体流行率最高。猪和鸡在传播人HEV中的作用值得进一步研究。更多还原

【Abstract】 Objective To investigate the prevalence of anti-HEV among swine,sheep and chickens. Methods Totally 498 sera of swine,sheep and chickens collected from Xingjiang,Guangxi,Guangdong,Beijing and Hebei were detected for the anti-HEV by an enzyme linked immunoassay. Results The anti-HEV positive rate of swine was 67.53%(104/154),in pigs between 4-5 months of age the rate was 100.00%(9/9) from Xingjiang. The rate in pigs under 3 months of age from Guangxi was 36.00%(9/25) and in pigs older than six months of age was 71.67% (86/120),respectively. The 108 sera of sheep collected from Xingjiang were all negative.The positive rate of chickens was only 1.27% (3/236). The anti-HEV prevalence rates of chickens from Luoding,Shenzhen,Liuzhou,beijing and Hebei were 4.00%,1.49%,1.49%,0,0 respectively. Conclusion HEV infection does exist among swine and chickens. The anti-HEV prevalence of swine was the highest among domestic animals. The role of swine and chickens in transmission of HEV needs to be further studied.更多还原
