Scrub typhus, caused by is a zoonosis that spreads rapidly in Shandong, China. To investigate the molecular characterization of in new and old epidemic areas in Shandong Province, we compared the genetic relationships of between Linyi and Tai’an districts, typical old and new epidemic areas in Shandong, respectively. was detected in blood from 12 of 16 patients in Linyi and in eschar from 3 of 4 patients in Tai’an; 17 of 128 rodents were found to be infected with in Linyi, and 4 of 68 rodents were found to be -positive in Tai’an. The results indicated less genetic variation in between the new and old epidemic areas, and the Sdu-1 type, similar to Japan Kawasaki, was the main genotype of in Shandong Province.
