Abstract
Recently, there have been reports of new members of posavirus-like viruses in the order Picornavirales. In this study, using a metagenomics approach, 11 posavirus-like sequences (>7,000 nucleotides) were detected in 155 porcine fecal samples. Phylogenetic analysis revealed that the newly identified virus sequences, together with other posavirus-like viruses, form distinct clusters within the order Picornavirales, composed of eight genogroups and unassigned sequences based on amino acid sequences of the helicase and RNA-dependent RNA polymerase regions, with <40 % and <50 % sequence identity, respectively. We propose further classifications of highly diverse posavirus populations based on newly identified sequences from Japanese pig feces.
