ML and BI consensus tree inferred for a subset of Anaplasma spp., using 226 sequences of the groEL gene, and an alignment length of 1224 bp. Best-fit evolutionary models calculated for the ML and BI methods were TIM + F + G4 (position-1); TN + F + G4 (position-2); and K3Pu + F + G4 (position-3); and M₄₅, M₁₃₆, M₁₄₂, M₁₃₀, M₁₃₉, M₁₈₅ (position-1); M₈₁, M₄₀ (position-2); M₁₅, M₅₀, M₈₅, M₁₂₂, M₉₀ (position-3), respectively. Bootstrap values and BPP are indicated above or below each branch. Colors for ecotypes I, II, III and IV were assigned according to Jaarsma et al. [8]. The position of the strain of A. phagocytophilum characterized in the present study is highlighted in a green box
