中文摘要：

用间接ELISA试剂盒对北京市郊区所采集的174份猪血清样品进行了抗体检测,结果显示,其抗体总阳性率达62.1%。针对戊型肝炎病毒（HEV）ORF2/ORF3重叠区设计了简并引物,采用巢式RT-PCR对随即采取的少量猪粪便样品进行了抗原检测。结果表明,部分粪便样品中存在HEV。

英文摘要：

To investigate hepatitis E virus（HEV） infection in pigs in Beijing suburbs,we collected 174 swine sera,and tested antibodies using ELISA kit.The results demonstrate that the total positive rate of anti-HEV antibodies was 62.1%.Responses in a nested RT-PCR assay to a pair of degenerated primers designed from ORF2/ORF3 overlapping region indicated presence of gene sequence of HEV in the stool samples.
