Figure 4. Phylogenetic analysis of partial sequences of A) viral protein (VP) 7 genes of the Burkina Faso G6P rotavirus (ROTAV) strains (nt 135–796), with G8 strain DRC88 as an outgroup. GenBank accession numbers for VP7 genes of reference strains are available in Technical Appendix Table 4. B) VP6 genes (nt 145–1217) of the G6P ROTAV strains from Burkina Faso, with I2 genotype specificity and reference strains from genotypes I1, I2, and I3. GenBank accession numbers. for VP6 genes of reference strains are available in Technical Appendix Table 5. Filled circles, Burkina Faso G6P ROTAV strains. Bo, bovine; Buff, buffalo; Hu, human. Po, porcine. Scale bars represent number of substitutions per site. Bootstrap values are shown at the branch nodes (values of <50% are not shown).
