| 摘 要： | 【目的】全面掌握了解广西各地猪、牛、羊、鸡戊型肝炎（HE）的感染状况及其流行特点。【方法】采用双抗原夹心ELISA检测来自广西各地猪（850份）、牛（392份）、羊（428份）、鸡（352份）共2022份血清中的抗HEV抗体，并比较不同地区、不同动物间抗HEV抗体阳性率的差异。【结果】4种主要畜禽的血清总抗HEV抗体阳性率为44.76%（905/2022），其阳性率大小排序为：猪（77.53%）＞牛（27.81%）＞羊（21.03%）＞鸡（13.35%）；不同地区的畜禽血清抗HEV抗体阳性率都是以猪群的最高，均在59.00%以上。而从不同地区的4种畜禽血清总抗HEV抗体阳性率来看，以南宁市的最高（61.94%）、河池市的最低（30.93%）。【结论】广西的猪、牛、羊、鸡群中均存在HEV感染，且猪在传播HEV方面起主导作用。

| Abstract: | Objective]The present study was conducted to investigate current status of infection and epidemiological characteristics of hepatitis E virus (HEV) in swine, chicken, cattle and sheep in Guangxi. Method]The anti-HEV antibodies were detected in 2022 sera including 850 of swine, 352 of chicken, 392 of cattle, and 428 of sheep, collected from all over Guangxi, using a double-antigen sandwich enzyme immunoassay (DS-ELISA), and the positive rate of anti-HEV antibody in different sera were compared. Result]Out of 2022 sera collected from these animals, 905 were positive anti-HEV, with a total positive rate of 44.76%. The declining order of positive rate in different animals was as follows: swine 77.53%, cattle 27.81%, sheep 21.03% and chicken 13.35%. Positive rate in sera of swine, irrespective of region, topped the list with the rate above 59.00%. Region wise, the total positive rate of four animals from Nanning was the highest (61.94%), whereas the lowest (30.93%) in Hechi. Conclusion]HEV infection occurred in all kinds of studied animals, of which swine played a leading role in the dissemination of HEV. |
