摘要
利用双抗原夹心酶联免疫吸附试验(ELISA)对2010年4月～12月间采自西藏自治区林芝地区林芝县和米林县藏猪的421份血清样品,进行猪戊型肝炎病毒血清流行病学调查,以期初步了解西藏自治区林芝地区藏猪群戊型肝炎(hepatitis E,HE)的感染情况和流行特点。结果显示,藏猪的HEV抗体平均阳性率为48.46%(204/421),其中种公猪的阳性率最高(75%),其次是育肥猪(60.58%),断奶仔猪的阳性率最低(31.88%)。从性别上看,公猪(52.63%)和母猪(47.89%)的抗体阳性率无显著差异(P>0.05),但林芝县(53.10%)和米林县(43.08%)猪群抗体阳性率存在显著差异(P<0.05)。结果表明,HEV在西藏自治区林芝地区普遍流行,应引起相关部门的重视。
The objective of the present investigation was to determine the seroprevalence of anti-HEV in Tibetan pigs in Tibet Nationality Autonomous Region,China.A total of 421 serum samples were randomly collected from Tibetan pigs in Tibet and were evaluated for antibodies against HEV using enzyme-linked immunosorbent assay（ELISA）.204（48.46%） of 421 samples were positive for HEV antibody,and breeding sows had the highest HEV seroprevalence（75%）,followed by fattening pigs（60.58%）,and piglets had the lowest HEV seroprevalence（31.88%）.Generally,there was no statistical difference between male（52.63%） and female（47.89%） Tibetan pigs for the positive rate of anti-HEV（P0.05）.Interestingly,the comparison between Nyingchi（53.10%） county and Mainling（43.08%） county showed that the positive rates of anti-HEV in these two regions had significant difference（P=0.04）.The results of the present investigation have implications for the ongoing control of HEV infection in Tibetan pigs in Tibet and elsewhere,China.
