Figure 4. Phylogenetic analysis of the VP7 gene of G8 rotavirus strains. This tree involves 8 different VP7 genes including G1, G2, G3, G4, G6, G8, G9 and G12. The G8 gene was further clustered into four lineages. Studied strains were marked in different shapes and colors. : G8P[8] strains in various regions; : animal-derived strains. The G8 strains detected in this study are indicated by purple lines. References RVA genotypes are labelled according to GenBank with their respective accession numbers. The trees were constructed in MEGA 6.0 through the maximum likelihood method using the Kimura 2-parameter model. The bootstrap values (1000 replicates) are indicated in the phylogenetic tree, and values less than 70% are not represented.
