Figure 2: Phylogenetic relationships based on the VP1, P1, P2, and P3 region sequences of EV-B.

Four Xinjiang EV-B106 strains (indicated by circles) and 56 other EV-B prototype strains were analysed by nucleotide sequence alignment using the neighbour-joining algorithms implemented in the MEGA 5.0 program. Numbers at the nodes indicate bootstrap support for that node (percentage of 1000 bootstrap replicates). The triangle and square indicates the Pakistan EV-B106 strain and Yunnan EV-B106, respectively. The scale bars represent the genetic distance. All panels have the same scale. (a) VP1 coding sequences; (b) P1 coding sequences; (c) P2 coding sequences; and (d) P3 coding sequences.
