Bayesian phylogeny of BH14680 in Bartonella strains and species. The branch tags show the Bayesian support and, if superior to 50, the number of times the split was present in 100 maximum likelihood bootstraps. The tree was rooted with B. bacilliformis (not shown on the tree). The positions of Houston-1, IC11 and UGA10 are indicated by arrows. Species are abbreviated as follows: BH, B. henselae; BG, B. grahamii; BQ, B. quintana. Colors on the branches represent three species: red, B. henselae; blue, B. quintana, orange, B. grahamii. Colors on the names denote genotype and geographic groups for B. henselae and B. grahamii, respectively. B. hensleae: red, ST1, green, ST5; purple ST2 (UGA24), ST4 (Cheetah), ST6 (UGA10 and Marseille), ST7, FR96. B. grahamii; orange, American strains; pink, European strains; brown, Asian strains. Green shades indicate potential recombination events across species.
