Figure 1. Phylogenetic analysis of the Guangdong strain collected in this study and all the EV-B prototype strains based on the entire VP1 sequences.

The Guangdong strain isolated in this study is indicated with a solid circle. The strain indicated by a triangle is the EV-B84 prototype strain. The tree was constructed using the Neighbour-Joining method and Kimura-two parameter model. The bootstrap support values were calculated for 1000 replicates and bootstrap support >80% are indicated for the main nodes.
