Emergence of Unusual G6P Rotaviruses in Children, Burkina Faso, 2009–2010
Figure 3. Phylogenetic analysis of partial sequences of viral protein (VP) 8 subunits of the VP4 gene of rotavirus (nt 141–751), with reference strains from all P lineages and with the P DRC88 strain as an outgroup. GenBank accession numbers for VP4 genes of reference strains are available in Technical Appendix Table 3. Filled circles, G6P rotavirus strains; triangles, G1P strains; squares, G3P strains; open circles, G1G6P strains from Burkina Faso, December 2009–March 2010. Scale bar represents the number of substitutions per site. Bootstrap values are shown at branch nodes (values of <50% are not shown).
