Maximum likelihood phylogenetic tree based on the ORF of the VP7 encoding gene segment, applying Tamura 3-parameter + gamma distributed (T92 + G) model: (A) G8 strains; (B) G9 strain. The study strains are indicated in red circles for MSD, black triangle for LSD and green square for children without diarrhoea. Roman numerals indicate lineages. Only bootstrap values ≥ 70% are shown adjacent to each branch node. The Wa-like RVA strain from the USA was included as an out-group. Scale bars indicate the number of substitutions per nucleotide position.
