Bartonella are vector borne gram-negative facultative intracellular bacteria. Bartonella species are associated with rodents and their flea parasites worldwide. The genetic variation and distribution of Bartonella species in rodents are not clear in China. We investigated the presence and genetic diversity of Bartonella species in rodents from eastern China. We captured rodents from 2015 to 2016 in Jiaonan County, Shandong Province, and detected Bartonella species in the spleen of rodents by PCR amplification of the citrate synthase (gltA) gene and RNA polymerase beta subunit (rpoB) gene. We found that 8.38% (16/191) of the rodents were Bartonella positive by PCR for both gltA and rpoB genes; that Bartonella sequences from the rodents were phylogenetically divided into five clades, which were closely related to B. tribocorum, B. rattimassiliensis, B. grahamii, B. fuyuanensis, and B. queenslandensis, respectively; and that each Bartonella species is rodent species-specific with B. rattimassiliensis and B. tribocorum for Rattus norvegicus, B. grahamii for Tscherskia triton, B. fuyuanensis for Apodemus agrarius, and B. queenslandensis for Niviventer confucianus. This study indicated that Bartonella organisms have a broad distribution and a variety of genotypes in rodents in eastern China and the threats to public health by these Bartonella species should be monitored in China.
