Abstract
Previously, we reported the discovery of a novel canine picornavirus (CanPV) in the fecal sample of a dog. In this molecular epidemiology study, CanPV was detected in 15 (1.11%) of 1347 canine fecal samples from Hong Kong and one (0.76%) of 131 canine fecal samples from Dubai, with viral loads 1.06×10(3) to 6.64×10(6) copies/ml. Complete genome sequencing and phylogenetic analysis showed that CanPV was clustered with feline picornavirus (FePV), bat picornavirus (BatPV) 1 to 3, Ia io picornavirus 1 (IaioPV1) and bovine picornavirus (BoPV), and this cluster was most closely related to the genera Enterovirus and Sapelovirus. The Ka/Ks ratios of all the coding regions were <0.1. According to the definition of the Picornavirus Study Group of ICTV, CanPV, FePV, BatPV 1 to 3, IaioPV1 and BoPV should constitute a novel genus in Picornaviridae. BEAST analysis showed that this genus diverged from its most closely related genus, Sapelovirus, about 49 years ago.
