Phylogenetic analysis of Rickettsia bellii

Rickettsia bellii (OP286852) was found only in I. persulcatus , and the sequence of R. bellii was randomly selected to construct the evolutionary tree. The sequence of R. bellii obtained in this study is displayed on the phylogenetic tree with squares ( Fig. 9b ). The phylogenetic tree of the 16S rRNA gene shows that R. bellii found in Inner Mongolia is on the same branch as R. bellii strain RML369-C ( NR 074484). The sequences were compared and analyzed with MEGA 7.0 software and showed that the 16S rRNA gene sequence of R. bellii from Inner Mongolia showed 94.23% homology with the R. bellii strain RML369-C ( NR 074484) isolated in Marseille, France.

(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).
