Figure 4From: Mutations in the non-structural protein region contribute to intra-genotypic evolution of enterovirus 71Bayesian MCMC analysis phylogeny of EV71 strains according to VP1 coding region in China. A total of 154 complete VP1 sequences of genotype C4 in China with known sampling dates were used to construct a phylogenetic tree as indicated. The tree is shown in decreasing order, and the estimated dates of common acenstors of nodes are indicated at the nodes.Back to article page
