Identification and molecular survey of Borrelia burgdorferi sensu lato in sika deer (Cervus nippon) from Jilin Province, north-eastern China.

In this study, the existence and prevalence of Borrelia sp. in sika deer from four regions of Jilin Province in China was assessed. Seventy-one blood samples of sika deer were collected and tested by nested-PCRs based on 16S ribosomal RNA (16S rRNA), outer surface protein A (OspA), flagenllin (fla), and 5S-23S rRNA intergenic spacer (5S-23S rRNA) genes of B. burgdorferi s.l. Six (8.45%) samples were positive for Borrelia sp. based on sequences of 4 genes. The positive samples were detected 18 for 16S rRNA, 10 for OspA, 16 for fla and 6 for 5S-23S, with the positive rates 25.35 (95% CI=3.8-35.6), 14.08 (95% CI=3.0-21.6), 22.54 (95% CI=4.3-36.9) and 8.45 (95% CI=1.7-22.9), respectively. Sequence analysis of the positive PCR products revealed that the partial 4 genes sequences in this study were all most similar to the sequences of B. garinii and B. burgdorferi sensu stricto (s.s.), no other Borrelia genospecies were found. This is the first report of Borrelia pathogens in sika deer in China. The findings in this study indicated that sika deer as potential natural host and may spread Lyme disease pathogen to animals, ticks, and even humans.
