Fig 2. Phylogenetic Analysis of Gardnerella Strains.

Maximum Likelihood species tree of Gardnerella strains based upon sequence homology within the core gene set. (A) Phylogenetic tree listing branch supports and distinction of the four clades within the tree. Numbers within black circles indicate the number of homologous genes within each clade and the core Gardnerella genome. (B) Maximum Likelihood tree including branch lengths and isolation information with respect to location and diagnosed symptom. Strains isolated from the bladder and sequenced in this study are labeled in red; strains listed in green were isolated from the vagina/endometrium of BV+ patients; strains in light blue were isolated the vagina/endometrium of STD+ patients. All remaining strains (indicated in black font) were isolated from the vagina or endometrium.
