Abstract
Posaviruses and posa-like viruses are unclassified viruses with sequence similarity to viruses of the order Picornavirales. They have been reported in various vertebrates and invertebrates. We identified 11 posavirus-like sequences in porcine feces and performed phylogenic analysis. Previously reported Japanese posaviruses and those identified in this study clustered with posavirus 1, 4, and 7 and husavirus 1, while five viruses branched into three independent lineages, tentatively named posavirus 10, 11, and 12. Interestingly, posaviruses, except for posavirus 8 and 9, husaviruses, and rasaviruses, formed a cluster consisting of viruses only from pigs, humans, and rats, while posavirus 8 and 9, fisavirus, and basaviruses clustered with posa-like viruses from invertebrates.
