Figure 2. Phylogenetic tree of Bartonella, as based on concatenated gltA and rpoB genes using a GTR substitution model.

The phylogenetic tree was constructed using a Bayesian method. Brucella abortus was included as an outgroup. Bootstrap values were calculated with 10,000,000 replicates. The corresponding accession number for each genotype is indicated below each species of Bartonella. The flea species from which Bartonella DNA was detected is indicated, and the locality and the location from where it was collected is noted in parentheses.
