Phylogenetic distribution of representative Orientia tsutsugamushiisolates from scrub typus patients in India, September 2010–August 2012. Isolates were identified on the basis of the 56-kDa TSA gene. The evolutionary history was inferred by using the neighbor-joining method. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) is shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as

Figure 2. Phylogenetic distribution of representative Orientia tsutsugamushiisolates from scrub typus patients in India, September 2010–August 2012. Isolates were identified on the basis of the 56-kDa TSA gene. The evolutionary history was inferred by using the neighbor-joining method. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) is shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed by using the maximum composite likelihood method (10). Scale bar indicates base substitutions per site.
