Phylogenetic tree of the dsb gene from Ehrlichia using the maximum likelihood method and Tamura–Nei model [41]; log likelihood − 1366.46. Sequences obtained in this study are marked with an asterisk (*). The percentage of trees in which the associated taxa clustered together is shown next to the branches. Initial tree(s) for the heuristic search were obtained automatically by applying Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances estimated using the maximum composite likelihood (MCL) approach, and then selecting the topology with the superior log likelihood value. The rate variation model allowed for some sites to be evolutionarily invariable ([+ I], 33.54% sites). The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. There was a total of 404 positions in the final dataset. Evolutionary analyses were conducted in MEGA X [42]
