| 摘 要： | 为了解云南省猪群戊型肝炎流行情况，从各地养猪场、屠宰场共采集270份血清，应用双抗夹心酶联免疫测定法（DS-ELISA）进行血清学调查。检测结果174份样品呈HEV-IgG抗体阳性，总阳性率64.4%，其中养殖场血清抗体阳性率为55.6%，屠宰厂为68.9%。比较养殖场的各年龄阶段猪群显示，母猪群血清抗体阳性率最高，为71.4%。本研究表明猪戊型肝炎在云南省也有存在，并呈一定的流行趋势，感染率随年龄增长而升高。

| Abstract: | To investigate the prevalence of Swine HEV infection in Yunnan province，the HEV-IgG antibody was applied to screen the swine sera collected from slaughter houses and pig farms with commercial DS ELISA kit.Our data indicated that among 270 sera samples tested，174 swine serum samples were positive for HEV-IgG antibody，the seroprevalence rate was 64.4% in general，55.6% for pig farms and 68.9% for slaughter houses，respectively.Among groups with different ages，the seroprevalence of sows was 71.4%，higher than that of others.It was shown that swine hepatitis E was endemic in Yunnan province，and the seroprevalence increased with the age. |
