Porcine noroviruses and sapoviruses on Korean swine farms

Porcine noroviruses and sapoviruses on Korean swine farms Porcine noroviruses (NoVs) and sapoviruses (SaVs), which belong to the family Caliciviridae , have been considered potential zoonotic agents for human infection, and several cases have been reported in Asian countries. In this study, a total of 537 porcine fecal samples collected from 64 swine farms in Korea were tested. Among 537 samples, porcine NoVs were detected by semi-nested RT-PCR in ten samples (1.9%), and porcine SaVs were detected by RT-PCR in 60 samples (11.2%), showing their circulation in Korea. The porcine NoVs were genetically related to strains of genotypes 11 and 18, of genogroup II (GII) of the genus Norovirus . The porcine SaV strains were genetically related to the porcine enteric calicivirus Cowden strain and to the previously identified Korean porcine strains in genogroup III (GIII) of the genus Sapovirus . In no case was co-infection with both NoV and SaV observed in one pig. This is the first report describing porcine NoVs identified in Korea. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

Porcine noroviruses (NoVs) and sapoviruses (SaVs), which belong to the family Caliciviridae , have been considered potential zoonotic agents for human infection, and several cases have been reported in Asian countries. In this study, a total of 537 porcine fecal samples collected from 64 swine farms in Korea were tested. Among 537 samples, porcine NoVs were detected by semi-nested RT-PCR in ten samples (1.9%), and porcine SaVs were detected by RT-PCR in 60 samples (11.2%), showing their circulation in Korea. The porcine NoVs were genetically related to strains of genotypes 11 and 18, of genogroup II (GII) of the genus Norovirus . The porcine SaV strains were genetically related to the porcine enteric calicivirus Cowden strain and to the previously identified Korean porcine strains in genogroup III (GIII) of the genus Sapovirus . In no case was co-infection with both NoV and SaV observed in one pig. This is the first report describing porcine NoVs identified in Korea.
