Abstract

To determine whether hepatitis E virus (HEV) was distributed in the population of wild boars in South Moravia between 1990 and 2008, a total of 366 samples of archived sera from wild boars were investigated using serological (commercial ELISA) and molecular (RT-qPCR) methods. A total of 31 (8.5%) wild boars were seropositive, and from two of them, RNA sequences were recovered by nested RT-PCR. The presented results, with one of the oldest animal's HEV-positive serum (collected in 1990), suggest that wild boars may be a reservoir of HEV in the Czech Republic and that this virus has been circulating in studied areas for more than 20 years.
