Abstract

Hepatitis E virus (HEV) and sapovirus (SaV) induce acute hepatitis and gastroenteritis, respectively, in humans. As pigs have been recognized as an important reservoir for these viruses, we evaluated the infection rates of both viruses using fecal samples collected from post-weaning pigs via RT-PCR methods. In the five swine farms assessed in this study, 3 farms were found to be HEV-positive and 4 farms were SaV-positive. The overall prevalence of HEV and SaV in the pigs was 17.0 and 23.1%, respectively. Phylogenetic tree analysis revealed that the isolated swine HEVs belonged to genotype 3 and the porcine SaVs belonged to genogroup III. This study proved that both HEV and SaV are prevailing in post-weaning pigs in Korea.
