Phylogenetic trees of coxsackievirus B1, coxsackievirus A6, and coxsackievirus A4 based on the partial VP1 sequences by the neighbor-joining algorithm implemented in MEGA (version 7.0) using the Kimura two-parameter substitution model and 1000 bootstrap pseudo-replicates, respectively. Only strong bootstrap values (> 75%) are shown. ● Indicates strains isolated in this investigation; ▲ indicates the prototype strain
