Figure 2: Evolutionary tree of Anaplasma and Ehrlichia sequences. Data was obtained from this study and similar sequences from other investigations, deposited in GenBank; Wolbachia pipientis included as outgroup. The scale bar indicates an evolutionary distance of 0.01 nucleotides per position in the sequence. Sequences derived from the present study are marked with asterisks. The percentage of trees in which the associated taxa clustered together is shown next to the branches.
