Fig. 3

Phylogenetic tree based on whole genome alignment of the 15 sequenced strains. The 15 sequenced M. pneumoniae strains and M. hominis (included as an outgroup) were aligned, and a tree was generated using the alignment. Confidence values, represented as percent of supporting bootstrapping iterations are shown for each node. Scale, in differences per site, is indicated at the bottom. The branches between M. hominis and the M. pneumoniae strains have been truncated (indicated by double slashes), and the branch length (in differences per site) is indicated above the branch. The inset shows the same tree (rescaled, note the new scale bar) without any branches truncated
