Figure 2. Phylogenetic relationships among Enterovirus C strains from human and non-human primates.

The NJ tree is based on the alignment of the full-length VP1 sequences. Studied viruses from apes are highlighted in bold red with host names indicated in brackets while human-derived isolates from Cameroon are specified in bold blue. Prototype strains are indicated by triangles (▴). For clarity, type and lineage-specific clusters containing exclusively human isolates have been collapsed. The scale is shown at the bottom as substitutions per site. Viral isolates belonging to enterovirus species commented in the text are gathered in grey-shaded boxes.
