Figure 4

Neighbor-joining tree of 3D polymerase (3Dpol) sequences of echovirus 30 (E30) study samples and sequences from previously described E30 strains. The tree was constructed from Jukes-Cantor corrected nucleotide sequence distances in MEGA version 7.0 (https://www.megasoftware.net). Colored circles represent clades G1–G6 from this study; black circles represent 581 previously described E30 strains; and unlabeled branches represent all other species B types (n = 1,566) available in GenBank as of October 18, 2019. Scale bar indicates nucleotide substitutions per site.
