Phylogenetic trees using amino acid sequences of P1, P2 and P3 and VP1 proteins. Phylogenetic trees were constructed using amino acid sequences of EV-A to EV-J and Japanese BEVs based on the maximum likelihood method in MEGA5.22 with bootstrap values calculated for 1000 replicates. Scale bar indicates amino acid substitution per site. BEVs in Japanese were indicated as ■. Simian sapelovirus (AY064708) was used as outgroup
