Phylogenetic analysis using VP1, partial 5′UTR and 2C gene sequences of enterovirus D68 (EV-D68) strains.The trees were inferred from (A) VP1, (B) partial 5′UTR and (C) partial 2C sequence data by the maximum likelihood (ML) method, with bootstrap values calculated from 1000 trees. Sequences for 918 nucleotide positions in each VP1 region, 356 nucleotide positions in each 5′UTR region, and 531 nucleotide positions in each 2C region were included in the analysis. Bootstrap values expressed as a percentage are shown at the nodes and the scale reflects the number of nucleotide substitutions per site along the branches. Only bootstrap values >70% are shown. Black circles indicate EV-D68 strains collected for the present study.
