Phylogenetic tree based on nucleotide sequences (700 nt) of the VP7 gene of porcine RVB strains described in this study and representative strains of the 26 previously identified RVB G genotypes12. The tree was constructed using the neighbor-joining method based on the Kimura 2-parameter model. The scale bar indicates nt substitutions per site. The bootstrap values (1000 replicates) are shown at the branch nodes (values < 80% not shown). The Brazilian porcine RVB strains are marked with filled circles.
