Strains A14, A23, A25, P02, P39, and P43 are shown in red. Gray shading indicates the 10 gene segments (VP7, VP6, VP1-3, and NSP1-5) with genotypes identical to those of strains A14, A23, A25, P02, P39, and P43. Green shading indicates the VP4 gene segments with a P[8] genotype identical to those of strains A14, A25, P02, P39, and P43. Blue shading indicates the VP4 gene segments with a P[6] genotype identical to that of strain A23. “−” indicates that no sequence data were available in the DDBJ and EMBL/GenBank data libraries. aThe gene segments that are most similar to those of strain A14. bThe gene segments that are most similar to those of strain A23. cThe gene segments that are most similar to those of strain A25. dThe gene segments that are most similar to those of strain P02. eThe gene segments that are most similar to those of strain P39. fThe gene segments that are most similar to those of strain P43.
