From: Molecular characterization of echovirus 12 strains isolated from healthy children in China
Phylogenetic relationships based on the P1, P2, and P3 coding sequences of 381 EV-B strains. Three E-12 strains and 378 EV-B strains were analysed by nucleotide sequence alignment using the neighbour-joining algorithms implemented in the MEGA 6.06 program. The numbers at the nodes indicate bootstrap support for that node (percentage of 1,000 bootstrap replicates). The scale bars represent the genetic distance. Only high bootstrap values (>75%) are shown. ▲ indicates the strain isolated in this investigation, and ● indicates the prototype strain. The red nodes denote the other E-12 strains. The complete trees are available in Supplementary Fig. S1.
