Fig 3. Phylogenetic analysis based on the O. tsutsugamushi 56-kDa TSA gene.
All the sequences of O. tsutsugamushi in this study marked with black triangles, were compared with other reference sequences available in GenBank. The MEGA 4.0 software was used for the phylogenetic analysis. The stability of the nodes was assessed using neighbor-joining cluster analysis with 1,000 bootstrap replications, and only bootstrap values.70% are shown at the nodes.
