Abstract:
Porcine 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 200 porcine fecal samples collected from Lulong county of China were tested. Among 200 samples, porcine sapoviruses were detected by RT-PCR in 17 samples (8.5%) showing their circulation in China. 14 out of 17 positive sapovirus strains were genetically related to the genogroup III (GIII) and were further divided into three different clusters or genotypes according to the phylogenetic analysis. In addition, the remaining three sapovirus strains belonged to GVII (one strain) and a potential novel genogroup (two strains) according to the phylogenetic analysis and the nucleotide identity and amino acid identity. These data suggested the genetic diversity of porcine sapoviruses in China.
