Figure 1

Figure 1. Phylogenetic analyses based on nucleotide sequences of the outer member protein A (307-bp) (A) and citrate synthase (1,150-bp) (B) genes of Rickettsia. Boldface indicates the newly discovered Rickettsia genotype (Rickettsia sp. XY99). Asterisks after taxon names indicate that the sequence of Rickettsia species was found in China. Neighbor-joining trees were conducted by using the maximum composite likelihood method by means of MEGA version 5.0 (http://www.megasoftware.net). Bootstrap analysis of 1,000 replicates was applied to assess the reliability of the reconstructed phylogenies. Scale bars indicate estimated evolutionary distance.
