Phylogenetic tree based on 16S sequences. Accession numbers are given for 16S sequences from A. platys and A. bovis. Other 16S sequences were taken from whole genomes with accession numbers as follows: A. centrale: CP001759; A. ovis Haibei: CP015994; A. marginale: CP00030; A. phagocytophilum: CP000235. Rickettsia felis (CP000053) was used as an out group. The evolutionary history was inferred using the Neighbor-Joining method [61]. The optimal tree with the sum of branch length = 0.23834825 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches [62]. The evolutionary distances were computed using the Kimura 2-parameter method [63] and are in the units of the number of base substitutions per site. Evolutionary analyses were conducted in MEGA7 [64]. This tree is representative of the Maximum Likelihood tree
