Hepatitis E virus (HEV) was detected in stools collected from wild boars in Italy, with an overall prevalence of 1.5 % (3/196). The sequence of a ~3.0-kb portion at the 3' end of the genome of one such strain, HEV/WB/P6-15/ITA, was determined. In the full-length ORF2, which encodes the capsid protein, the virus was genetically closest to wild boar and human HEV strains currently classified as genotype 3 subtype c. Interestingly, the 3' end of ORF2 of the WB/P6-15/ITA matched the 340-nucleotide (nt) sequence (94.0 % nt identity) of the human strain PeGe, identified in 2015 from a patient with acute hepatitis E in Genoa, Italy, suggesting that similar HEV strains are circulating in the same geographical setting in humans and animals.
在意大利从野猪粪便中检测到戊型肝炎病毒（HEV），总体患病率为1.5%（3/196）。确定了其中一株病毒HEV/WB/P6-15/ITA基因组3'端约3.0 kb部分的序列。在编码衣壳蛋白的全长ORF2中，该病毒在基因上与目前归类为3型c亚型的野猪和人类HEV毒株最为接近。有趣的是，WB/P6-15/ITA的ORF2 3'端与2015年在意大利热那亚一名急性戊型肝炎患者中鉴定出的人类毒株PeGe的340个核苷酸（nt）序列匹配（nt同一性为94.0%），这表明相似的HEV毒株在人类和动物的同一地理区域传播。
