Abstract:The objective of this study was to understand the status of rats, the reservoir hosts of Borrelia burgdorferi, in the six representative provinces in China including Jilin, Shanxi, Gansu, Qinghai, Guizhou and Hunan. The rats were catched in two different areas in each province and the pathogens were isolated and cultured. NestedPCR was used to test Borrelia burgdorferi in spleen, kidney and bladder of rats. The sequence analysis was used to identify the genotype. Results indicated that two strains of Borrelia burgdorferi were obtained from apodemus in Guizhou; the specific fragments of Borrelia burgdorferi were obtained in spleen and kidney of rats from all representative provinces in China expect Guizhou; the PCR positive rate was higher in Huangnan (28.85%) and Shimen (19.6%); there were statistical differences in the areas. The sequence analysis shows that the genotype in Jilin, Qinghai, Gansu and Shanxi belongs to Borrelia garinii, and in Hunan belongs to Borrelia valaisiana. The results indicated that there were different infection rate in rats infected in the six provinces, thus further investigation should conduct for the primary reservoir hosts and for the pathogens carrying situation in different areas of China.
