Abstract

Objective To examine the infection rate and genotype of Borrelia sp. among rodents, we surveyed rodent samples from Bayannur region of Inner Mongolia Autonomous Region, and to provide basic information of epidemic prevention and risk assessment for local area. Methods During 2015-2016, rodent samples were collected in Bayannur region by the trap-night method, and rodent spleen DNA samples were examined using specific PCR to detect the Borrelia sp. Results A total of 480 rodents were collected from Bayannur, and Meriones meridianus accounted for 174, and M. unguiculatus 124. The results showed that both were the predominant species in these areas. Borrelia sp. were identified from 8 (1.67%)when amplified by PCR targeting flaB gene and 16S rDNA, including 6 cases of M. unguiculatus and 2 cases of Phodopus sungorus, the positive rate were 7.14% and 4.84%, respectively. Sequence analysis of the amplification products showed identification of B. garinii and B. afzelii with 100% homology, respectively. Conclusion In this study, we confirmed the B. garinii and B. afzelii were main pathogens transmitting among rodents in Bayannur region, it is necessary to implement monitoring and prevention of Lyme diseases.
