Figure 2. Phylogenetic tree of Bartonella species based on intergenic transcribed spacer sequence alignment for the isolates from the gray foxes, red foxes, and raccoons. Raccoon and gray fox isolates are shown for comparison. The tree shown is a neighbor-joining tree based on the Kimura 2-parameter model of nucleotide substitution. Bootstrap values are based on 1,000 replicates. The analysis provided tree topology only; the lengths of the vertical and horizontal lines are not significant.
