Phylogenetic analysis of Rickettsia raoultii The R. raoultii (OP286857) sequences were randomly selected to build a phylogenetic tree, named after regions and displayed on the phylogenetic tree with squares (Fig. 9c). The phylogenetic tree of the 16S rRNA gene shows that R. raoultii found in Inner Mongolia is on the same branch as R. raoultii strain IM 16 (KY474575) and R. raoultii isolate Binxian-91 (MN 446747). The sequences were compared and analyzed with MEGA 7.0 software and show that the 16S rRNA gene sequence of R. raoultii in Inner Mongolia is 100% homologous with the R. raoultii IM 16 strain (KY474575) in China and R. raoultii (MN 446747) found in Haemaphysalis longicornis in Bin County, Shanxi Province.
