摘要
目的调查孝感地区商品猪的戊型肝炎病毒(HEV)急性感染情况,为制定HEV防治方法提供理论依据。方法抽查孝感市19个乡镇的24个规模养殖场和45个散养养殖户共228头商品肉猪,采用酶联免疫吸附试验(ELISA)检测猪血清中抗HEV-Ig M,并进行分析。结果在228头商品猪中,抗HEV-Ig M总阳性率为14.0%,散养抗HEV-Ig M阳性率12.5%,规模养殖阳性率15.2%,差异无统计学意义(P>0.05)。19个乡镇中,阳性率最高乡镇为46.7%,5个乡镇阳性率为0,各乡镇之间有统计学意义(P<0.05)。结论孝感地区商品猪普遍存在HEV急性感染,应加强控制商品猪的HEV传播和易感人群的防护。
Objective To survey the prevalence of acute hepatitis E virus（HEV）infection of commercial pigs in XiaoganArea,so as to provide the evidence for control of the spread of HEV infection. Methods The serum samples were collectedfrom 228 adult commercial pigs in 24 scale farms and 45 free-range farmers of 19 towns in Xiaogan City. Anti-HEV Ig M wastested by the commercial ELISA kit. Results The total anti-HEV-Ig M positive rate was 14.0% from 228 pigs. The anti-HEV-Ig M positive rate was 12.5% in the free-range farmers and it was 15.2% in the scale breeding. There was no statisticaldifference between the two groups（P0.05）. Among the 19 towns,the highest positive rate in a town was 46.7%,the positiverates were 0 in 5 towns,and there was a statistically significant difference among all the towns（P0.05）. Conclusion Thereis a widespread acute HEV infection of commercial pigs in Xiaogan Area. Therefore,the control of HEV transmission andprotection of vulnerable groups should be strengthened.
