Phylogenetic analysis of Coxiella

The Coxiella (OP286858) sequences were randomly selected to build a phylogenetic tree, named after regions and displayed on the phylogenetic tree with squares ( Fig. 9e ). The phylogenetic tree of the 16S rRNA gene shows that Coxiella found in Inner Mongolia is on the same branch as uncultured Coxiella sp. clones DX-56 ( JX 432012) and DX-68 ( JX 432013). The sequences were compared and analyzed using MEGA 7.0 software. The results show that the homologies between the 16S rRNA gene sequence of Coxiella in Inner Mongolia and the sequences of Coxiella DX-56 ( JX 432012) and Coxiella DX-68 ( JX 432013) are 99.93% and 99.66%, respectively.

(a) Phylogenetic tree of Rickettsiales bacterium Ac37b identified in Inner Mongolia; the 16S rRNA gene sequences obtained in this study are marked with black squares (1320 bp) and triangles (1430 bp). (b) Phylogenetic tree of Rickettsia bellii identified in Inner Mongolia; the 16S rRNA gene sequences obtained in this study are marked with black squares (1109 bp). (c) Phylogenetic tree of Rickettsia raoultii identified in Inner Mongolia; the 16S rRNA gene sequences obtained in this study are marked with black squares (855 bp). (d) Phylogenetic tree of Anaplasma identified in Inner Mongolia; the 16S rRNA gene sequences obtained in this study are marked with black squares (1455 bp) and triangles (547 bp). (e) Phylogenetic tree of Coxiella identified in Inner Mongolia; the 16S rRNA gene sequences obtained in this study are marked with black squares (1463 bp).
