Rotaviruses, the major causative agents of infantile diarrhea worldwide, are, in general, highly species-specific. Interspecies virus transmission is thought to be one of the important contributors involved in the evolution and diversity of rotaviruses in nature. Human rotavirus (HRV) G3P[3] strains Ro1845 and HCR3A have been reported to be closely related genetically to certain canine and feline rotaviruses (RVs). Whole genome sequence and phylogenetic analyses of each of these 2 HRVs as well as 3 canine RVs (CU-1, K9 and A79-10, each with G3P[3] specificity) and 2 feline RVs (Cat97 with G3P[3] specificity and Cat2 with G3P[9] specificity) revealed that (i) each of 11 genes of the Ro1845 and HCR3A was of canine/feline origin; (ii) canine and feline rotaviruses with G3P[3] specificity bore highly conserved species-specific genomes; and (iii) the Cat2 strain may have evolved via multiple reassortment events involving canine, feline, human and bovine rotaviruses.
