中文摘要：

目的了解广西地区猪、鼠和狗血清中抗．戊型肝炎病毒（HEV）IgG抗体流行情况。方法应用HEV基因1型开放读码框（ORF）2和ORF3多肽包被酶标板，辣根过氧化物酶（HRP）标记的羊抗猪、羊抗鼠和羊抗狗建立的酶联免疫吸附试验（ELISA）法检测猪、鼠和狗血清中抗．HEV IgG。结果总抗．HEV IgG阳性率为31．84％（170／534），其中猪血清抗．HEV IgG阳性率为26．40％（66／250），鼠血清抗．HEV IgG阳性率为43．02％（77／179），狗血清抗．HEV IgG阳性率为25．71％（27／105）。结论猪、鼠和狗血清中存在HEV感染，鼠抗．HEV IgG阳性率最高。

英文摘要：

Objective To investigate hepatitis E virus （HEV） infection in swine, rats and dogs in Liuzhou of Guangxi. Methods Anti-HEV IgG was detected in sera of swine, rats and dogs by an enzyme-linked immunoabsorbent asaay （ELISA）, which was developed using the synthetic peptides derived from genotype 1 HEV ORF2 and ORF3 sequences. Results The total anti-HEV IgG positive rate was 31.84 % （170/534） from all animals tested. Anti-HEV IgG positive rates of swine, rats and dogs were 26.40% （66/250）,43.02% （77/179） and 25.71% （27/105） respectively. Conclusion Swine, rats and dogs could be infected by HEV, and the prevalence rate of anti-HEV IgG was the highest in rats.
