Enterovirus Co-infections and Onychomadesis after Hand, Foot, and Mouth Disease, Spain, 2008
Figure 3. Maximum likelihood phylogenetic reconstructions for coxsackievirus A6 based on partial viral protein 1 sequences. A) 5′ partial coding region (81 strains, 293 nt). B) 3′ partial coding region (68 sequences, 377 nt). Bootstrap values >75% are shown. Scale bars indicate number of substitutions per nucleotide position. Multiple strains from the same country sharing the same node were collapsed and shown as triangles with shape proportional to branch distances and number of sequences.
