Phylogenetic tree of the GroEL (top) and gltA (bottom) of different Anaplasma and Ehrlichia species and their relation with N. mikurensis and related species. Ehrlichia schotti/N. mikurensis sequences from I. ricinus (n = 26) and rodents (n = 11), which were generated in this study are depicted in bold. Other GroEL and gltA sequences were taken from Genbank. Their accession numbers are shown between brackets. The evolutionary distance values were determined by the method of Kimura, and the tree was constructed according to the neighbour-joining method. Bootstrap values higher than 90%, are indicated at the nodes.
