From: The diversity and evolutionary relationships of ticks and tick-borne bacteria collected in China
The abundance of tick-associated bacterial groups based on the groEL gene and the proportion of positive libraries of each group; Rickettsiales (NA) represented bacteria identified could not classified in a specific genus (A). Phylogenetic trees for bacteria from the order Rickettsiales based on groEL gene (B), genera Coxiella based on groEL gene (C) and Borrelia based on flaB gene (D). The trees were midpoint-rooted, and the scale bar represents the number of nucleotide substitutions per site. Sequences generated in this study marked by a circle and colored according to different tick genera. Bootstrap values only shown for major nodes. Within the Rickettsiales phylogeny, different genera are denoted by vertical lines. Within the Coxiella phylogeny, the position of C. bernetii is highlighted by a black arrow. Within the Borrelia phylogeny, “RF” denotes the Relapsing fever group, “REB” denotes the Reptile and echnida-associated Borrelia, while “LB” indicates the Lyme borreliosis group [69]
