Abstract
Objective: Genetic characterization of four strains of Borrelia burgdorferi isolated in China. Methods: PCR technique was used to amplify the 5s-23s rRNA intergenic spacer DNA from the whole cellular DNA of isolates GXLD-4,9,18 and Chang 14. The amplified products were then cloned into plasmid pGEM-T Easy and sequenced. Results: The 5s-23s rRNA/intergenic spacer DNA of the four isolates was 242bp, revealing a nucleotide sequence identity of > 99%. The four isolates had higher sequence identified with B. valaisiana than with other genomic groups. Conclusion: The four isolates most likely belong to Borrelia valaisiana genomic group.
