Phylogenetic tree based on the entire <i>VP1</i> nucleotide sequences (852 bp) of the CVB3 strains.

<p>12 CVB3 isolates from this study and 46 CVB3 strains worldwide were used to build the tree. Bootstrap values (%) for 1000 replicated trees are indicated at the nodes, where only values >80% are shown. Shijiazhuang isolates are labeled by blue solid squares, and the CVB3 prototype strain is labeled by a red solid circle. Abbreviations: SJZ, Shijiazhuang; HeB, Hebei; JL, Jilin; GD, Guangdong; SD, Shandong; AH, Anhui; BJ, Beijing; YN, Yunnan.
