Fig. 2
Maximum clade credibility (MCC) phylogeny of 34 3Dpol sequences coxsackievirus B2. For each branch, the thickness indicates the state probability and the color indicates the most probable location. Support values are indicated on the major nodes. The genotypes and nucleotide/amino acid similarity within genotypes are shown on the right. For each strain name, the VP1 genotypes are differentiated by colors (Cluster I: purple, Genotype II: green, Genotype III: orange, Genotype IV: blue, and Genotype V: grey), whereas the 3Dpol genotypes are differentiated by shading (Genotype A: purple, Genotype B: green, Genotype C: orange, Genotype D: blue, and Genotype E: gray). The branch length is proportional to the evolutionary time, and the scale bar is proportional to calendar time
