Genetic Variants of Orientia tsutsugamushi in Domestic Rodents, Northern China
Figure. . Phylogenetic relationships of Orientia tsutsugamushi detected in domestic rodents and human patients with scrub typhus in rural areas of Tai’an, Shandong Province, China, September 2010 through March 2012. Relationships were determined on the basis of the partial 56-kDa type-specific antigen gene of O. tsutsugamushi 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. Sampling sources and sampling date are also indicated for sequences determined in the study. Solid triangle indicates sequences determined in this study. Scale bar indicates genetic distance.
