Fig 1. Phylogenetic tree of the VP8* fragment of the VP4 genes of Ghanaian P[8]a strains and published P[8]a strains constructed using maximum likelihood method with Mega 6.06 software.

P[8]a strains analysed in the present study are indicated in red font. The prototype G1P[8] strain Wa and the P[8] vaccine strains in Rotarix and RotaTeq are in green font. Phylogenetic tree was supported statistically by bootstrapping with 1000 replicates. The scale bar at the bottom of the tree indicates genetic distance expressed as nucleotide substitutions per site. Percentage bootstrap support values ≥70% are shown.
