[Heterogeneity of the gene P83/100 of Borrelia borrelia burgdorferi sensu lato complex].

The 35 full-length Borrelia burgdorferi sensu lato complex a83/100 gene nucleotide sequences were determined. High level of homology was observed in the nucleotide sequences corresponding to the strains and isolates of Borrelia fzelii. The analysis of the nucleotide sequences revealed two groups of Borrelia garinii.
