摘要
目的分析戊型肝炎病毒(HEV)在长春地区动物群中的感染情况及戊型肝炎病毒系统进化关系。方法用抗-HEV抗体试剂盒检测长春地区猪、牛、羊、鹿、鸡和马血清中的抗体;对部分血清用RT-PCR检测HEVRNA,并对PCR阳性产物进行克隆测序及序列分析。结果493份猪血清中有427份为抗-HEV抗体阳性,阳性率为86.61%;有5份为HEVRNA阳性,5株克隆的核苷酸序列的同源性为91.2%~99.1%,该5株克隆的序列在ORF2区348bp与1~4型间核苷酸同源性分别为77.8%~82.3%、77.2%~78.1%、77.2%~99.1%和85.2%~95.2%;266份牛血清中有122份为抗-HEV抗体阳性,阳性率为45.86%;93份羊血清中有7份为抗-HEV抗体阳性,阳性率为7.53%;798份鹿血清中有348份为抗-HEV抗体阳性,阳性率为43.61%;369份鸡血清中有18份为抗-HEV抗体阳性,阳性率为4.88%;197份马血清中有31份为抗-HEV抗体阳性,阳性率为15.74%。结论HEV在多种动物群中均有流行,但在猪群中的流行率明显高于其他动物群。猪感染的HEV的基因序列与人群中散发性戊型肝炎病毒的基因4型同源性最高。进化关系表明,在长春地区猪与人HEV应划为一个分支。
