Abstract

We have reported a novel bovine rotavirus, the AzuK-1 (G21P[29]) strain, isolated from an asymptomatic calf. We isolated another bovine rotavirus, the Dai-10 strain, bearing new G24P[33] genotypes, assigned by the Rotavirus Classification Working Group (RCWG), from an asymptomatic cow in Hyogo Prefecture, Japan in 2007. To gain an insight into the origins and evolution of these strains, we determined the complete ORF sequences of all 11 genes of the two strains. The NSP3 genes of both strains were confirmed to belong to a new NSP3 genotype, T9, y the RCWG. Genotype determination of AzuK-1 and Dai-10 strains revealed that eight gene egments of both strains possessed genotypes typically observed in bovine rotaviruses, with the xception of VP4, VP7 and NSP3 gene segments. Unexpectedly, phylogenetic analyses showed hat VP6 and NSP2 gene segments of the AzuK-1 and Dai-10 strains were clustered with those of simian or canine/feline rotaviruses, rather than with those of bovine rotaviruses. These findings indicate the possibility that both strains originated by interspecies transmission and multiple reassortment events involving bovine, simian and canine/feline rotaviruses, resulting in the introduction of some genes into the genetic background of bovine rotaviruses.
