Phylogenetic tree clustering of the partial groEL of Ehrlichia spp. The tree was obtained using a Hasegawa–Kishino–Yano substitution model with gamma-distributed rate variation across sites (HKY + G) with the software MrBayes 3.2.7 [14] by Bayesian approach with Markov Chain Monte Carlo sampling (10,000,000 generations sampling every 1000 steps). This analysis involved 47 nucleotide sequences. The nucleotide sequence of Neoehrlichia mikurensis was used as an outgroup. The isolate identified in this study is indicated in bold
