Seasonal fluctuation of chigger mites on domestic rodents in Shandong, northern China.

Phylogenetic tree based on partial 56-kDa type-specific antigen gene of Orientia tsutsugamushi. The phylogenetic analysis was performed using the neighbor-joining method with Kimura 2-parameter distance model. Solid triangle indicates sequences determined in this study. Hollow circle and diamond indicate sequences previously determined in scrub typhus patients and domestic rodents in the study area. Scale bar indicates genetic distance.
