Abstract

Rabbits are considered a new natural reservoir of hepatitis E virus (HEV). In this study, HEV infection was verified by the detection of partial genomic sequence of HEV and anti-HEV antibodies in specific pathogen-free (SPF) rabbits. HEV RNA was found in 6.4% serum and 13.5% fecal samples from 126 SPF rabbits. Anti-HEV antibodies were also detected in 4.0% of the SPF rabbits. HEV genetic sequences isolated from the rabbits were clustered into a rabbit HEV clade with other rabbit HEV isolates; they were found to be most closely related with a rabbit HEV sequence previously reported in Korea. Therefore, HEV infection should be diagnosed before conducting experiments involving SPF rabbits.
