Phylogenetic analysis of the VP7 gene of RVA strains G3BP and G14P. Rotavirus strains were denominated as reported previously . The nucleotide sequences (nucleotides 104 to 906) of the VP7 gene were used to conduct a phylogenetic analysis. Black dots indicate the VP7 genes of equine RVA strains used in the virus-neutralizing test. Genome positions correspond to that of RVA/Horse-tc/JPN/HO-5/1982/G3P (GenBank accession number AB046464). RVA/Horse-wt/GBR/L338/1991/G13P is included as an outgroup. Percentage bootstrap support is indicated by the value at each node; values of <70 have been omitted.
