Objective The present study was conducted to investigate the infection of Borrelia burgdorferi in rodents in Kaihua county. Methods Nested PCR were used to amplify 5S-23S rRNA spacer fragments of B. burgdorferi from kidney samples of rodents captured by mouse cage in Kaihua county. And the positive samples were sequenced and analyzed. Results A total of 10 rodents were positive in 149 samples tested,with the prevalence of 6.71%. The positive samples were identified from Rattus edwardsi, Niviventer niviventer, N. fulvescens, R. tanezumi, Apodemus agrarius, and R. norvegicus. The predominant species in Kaihua county were Ap. agrarius, R. fulvescens, and N. niviventer and the positive rates were 4.05%, 10.00%, and 10.00%, respectively. The spleen specimens from the N. confucianus and N. fulvescens were positive for B.burgdorferi sensu stricto, and that from R. norvegicus was positive for B.valaisiana. Conclusion The N. confucianus and N. fulvescens are considered as important reservoirs. The infection of two B. burgdorferi genotypes in rodents was confirmed in Kaihua county. It is very important to enhance the B. burgdorferi surveillance in wild animals and focus the morbidity in population.
