Phylogenetic trees for the five Aichi virus strains. Phylogenetic analysis were performed using the neighbor-joining method and evaluated using the interior branch test method with Mega 4 software. Values for various branches are percentages of the tree obtained from 1000 resamplings of the data. (A) Neighbor joining tree constructed basing on the complete genomes. (B) Neighbor joining tree constructed using the nt 261-852 region; (C) Neighbor joining tree constructed using the rest genomic region.
