Phylogenetic trees using nucleic acid sequences of 5′UTR and 3′UTR. Phylogenetic trees were constructed using nucleic 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 nucleotide substitutions per site. BEVs in Japanese were indicated as ■. Simian sapelovirus (AY064708) was used as outgroup
