| Abstract: | Hepatitis E virus (HEV) is known as a causative agent of zoonosis and food poisoning.Pigs and some species of wild animals, including wild boar, are known to be a reservoir ofHEV. In this study, we investigated the situation regarding HEV infection in wild boars inIbaraki Prefecture, Japan. Serum, liver and feces samples from 68 animals were collected,and the presence or absence of HEV genomic RNA and HEV antibodies were analyzed. The viralgenome was detected in samples from 7 (10.3%) animals, with all HEVs classified asgenotype 3, subtype 3b. HEV antibodies were detected in samples from 28 (41%) animals.This report demonstrates for the first time the high prevalence of HEV infection in wildboars in Ibaraki Prefecture. |
