Molecular Characterization of the Porcine Group A Rotavirus NSP2 and NSP5/6 Genes from São Paulo State, Brazil, in 2011/12

Figure 1

Phylogenetic tree constructed with the neighbor-joining method using maximum composite likelihood as substitution model for a partial region (975 bp) of the NSP2 gene of the group A porcine rotavirus of the strains SWRV1 and SWRV7 with others representing human and animal GARVs. The scale represents the number of substitutions per site. Only bootstrap values >70% are shown. Pig strains defined in the present study are preceded by black triangles, and they are identified as accession number/host/strain/NSP2 genotype.
