Figure. Phylogenetic tree based on complete VP1 sequences among FDJS03 isolates and other strains of echovirus 30 from different geographic and temporal origins. The neighbor-joining method was used to construct the tree. Numbers at the nodes represent the percentage of 100 bootstrap pseudoreplicates that contained clusters distal to the node. Prototype strain Farina of echovirus 21 (shown as E21) was included as the outgroup, but the tree is unrooted.
