Hepatitis E is believed to occur in both endemic and sporadic forms in developing countries, which causes a major public health problem in Asia and Africa (Meng, 2010; Wang et al., 2016a). Recent studies have documented that the disease is also endemic in many industrialized countries (Wenzel et al., 2011). The causative agent, hepatitis E virus (HEV), belonging to the genus Orthohepevirus, is a non-enveloped RNA virus with a single-stranded, positive-sense genome of approximately 7.2 kb (Smith et al., 2014). The genome consists of a short 5' un-translated region (UTR), three open reading frames (ORFs), and a 3' UTR containing a poly(A) tail (Meng, 2011). Four recognized major genotypes of HEV are identified: genotype 1 (Asian and African strains), genotype 2 (a Mexican strain), genotype 3 (primarily from America and Europe, and some Asian countries), and genotype 4 (mainly Asian strains) (Smith et al., 2016). Previous study revealed that HEV genotype 4 is the dominant zoonotic HEV genotype in China (Wang et al., 2016a). However, infections with HEV 3 have been found more commonly in recent years in China (Liu et al., 2012; Zhang et al., 2013). To date, only one full genome of Chinese swine genotype 3 HEV strain from Shanghai has been documented (Si et al., 2009). We report here the first full genome sequence of a genotype 3 swine HEV strain from Zhejiang, China.


结论:浙江株戊型肝炎病毒(ZhJ-PJ050-3)基因组由7223个核苷酸组成,其中3’非编码区含有23个碱基的poly(A)尾。全基因组包含ORF1、ORF2和ORF3三个主要基因,长度分别为5109、1983和342 bp。进化分析显示,ZhJ-PJ050-3为基因3型,与国内唯一报道的上海株3型毒株以及多数日本毒株共属3b亚型。与国内外戊型肝炎序列比对发现,ZhJ-PJ050-3基因组共有24个特有的点突变,且在ORF1中含有一个亮氨酸缺失。这些分子特征将为下一步的研究提供方向。
