Fig 2. Phylogenetic tree of the VP7 sequences of G1P[8] strains and reference G1 strains retrieved from the GenBank database.

Fig 2

The tree was constructed using maximum likelihood method with Mega 6.06 software. G1 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. The closest G1 sequences from African rotaviruses to our study strains are indicated in blue font. The 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.
