Recombination of Human Coxsackievirus B5 in Hand, Foot, and Mouth Disease Patients, China
Figure. . Phylogenetic analysis of selected human coxsackievirus B (CBV) strains from different origins based on the viral protein 1 gene sequences. The neighbor-joining tree was generated by using MEGA4 software (www.megasoftware.net), and the prototype strain of coxsackievirus A (CAV) 16 was used as outgroup. The Changchun strains isolated in this study are indicated by triangles and other Chinese CBV5 strains are indicated by squares. Scale bar indicates nucleotide substitutions per site.
