Fig. 3. Genomic diversity and epidemiological factors of M. catarrhalis. Maximum likelihood phylogenetic tree of M. catarrhalis, considering only phylogroups A and B. The metadata includes geographic location (GL), year of collection (YC), clinical presentation (CP) and lineage classification (l). The letters A and B correspond to the classification of phylogroups: A represents the SR lineage and B the SS lineage.
