Phylogenetic tree showing the position of A. marginale amplified from R. bursa and cattle, A. ovis, “Ca. Anaplasma corsicanum”, Anaplasma sp. ovis-like, “Ca. Anaplasma mediterraneum” amplified from sheep and Anaplasma sp. marginale-like amplified from goats, compared to other species. The evolutionary history was inferred by using the maximum likelihood method based on the Hasegawa-Kishino-Yano model. A discrete Gamma distribution was used to model evolutionary rate differences among sites [2 categories (+G, parameter = 0.3880)]. The analysis involved 43 nucleotide sequences. All positions containing gaps and missing data were eliminated. There was a total of 861 positions in the final dataset. The scale-bar represents a 10% nucleotide sequence divergence
