Fig. 5

Neighbor-joining phylogenetic tree based on the p-distance among the nucleotide sequences of the VP7 segment for Rotavirus B. Along the branches, percentage of bootstrap values based on 10,000 replicates. Only values equal or larger than 80% are shown. The dataset contains 58 reference sequences representing the 26 RVB VP7 genotypes described plus the 8 sequences – marked with a circle – reported in this work. The division of genotypes is based on the 80% nucleotide cut-off value proposed by [25]; accordingly, two new genotypes (labelled as GX1 and GX2 in the Figure) are tentatively proposed
