Abstract

Sapoviruses (SaV) are enteric viruses infecting humans and animals. SaVs are highly diverse and are divided into multiple genogroups based on structural protein (VP1) sequences. SaVs detected from pigs belong to eight genogroups (GIII, GV, GVI, GVII, GVIII, GIX, GX, and GXI), but little is known about the SaV genogroup distribution in the Japanese pig population. In the present study, 26 nearly complete genome (>6000 nucleotide: nt) and three partial sequences (2429nt, 4364nt, and 4419nt in length, including the entire VP1 coding region) of SaV were obtained from one diarrheic and 15 non-diarrheic porcine feces in Japan via a metagenomics approach. Phylogenetic analysis of the complete VP1 amino acid sequence (aa) revealed that 29 porcine SaVs were classified into seven genogroups; GIII (11 strains), GV (1 strain), GVI (3 strains), GVII (6 strains), GVIII (1 strain), GX (3 strains), and GXI (4 strains). This manuscript presents the first nearly complete genome sequences of GX and GXI, and demonstrates novel intergenogroup recombination events.
