Fig. 3.

Majority-rule consensus phylogram inferred from an alignment of A. phagocytophilum groESL sequences. Bayesian analyses of phylogeny were performed using MrBayes v. 3.1.2. Identical sequences were excluded from analysis and reincluded for this figure. Values of nodal support are Bayesian posterior probabilities. For nodes recovered in both Bayesian and ML analyses, ML bootstrap confidence values exceeding 50 % are also shown. Branch lengths are in units of expected number of nucleotide substitutions per site.
