In 557 mites collected from rodents in the Changbai Mountain Area, 3 pools of Eulaelaps stabularis from Apodemus peninsulae and Apodemus agrarius showed a positive result by PCR amplifications of both the citrate synthase encoding gene (gltA) and outer membrane protein B encoding gene (ompB) of Rickettsia spp. Sequence analysis indicated that both gltA and ompB shared the high similarity (99%) to Rickettsia felis . The data presented in this paper extend the knowledge on the geographic distribution and host information of R. felis -like organism in China.
