FIG 3.

Phylogenetic trees of full-length ORF nucleotide sequences of RVA VP4 (A) and VP7 (B) gene segments showing close genetic relatedness to typical Wa-like genotype G1P[8] strains. Red, Cameroonian human RVA strain identified in this study; blue, Cameroonian bat RVA strains. Trees were constructed using the GTR+G+I nucleotide substitution model using RAxML, with the autoMRE flag, which enables a posteriori bootstrapping analysis. Only bootstrap values greater than 70% are shown. Bars indicate nucleotide substitutions per site.
