Phylogenetic analysis utilizing 56-kDa partial gene. Phylogenetic relationships of Orientia tsutsugamushi detected in human patients with scrub typhus in eastern Indian population. Relationships were determined based on the partial 56-kDa type-specific antigen gene by the minimum-evolution method with the Kimura 2-parameter distance model. Bootstrap values > 50% are shown at the branches. Location and GenBank accession numbers are indicated for each sequence. A solid triangle indicates sequences determined in this study
