FIG. 2.

Sequences of the 5S-23S rRNA intergenic spacers of Borrelia sp. strain A14S and the type strains of B. burgdorferi species known to be pathogenic to humans. Gaps were introduced to obtain maximum levels of homology. The nucleotides identical among all isolates are indicated with asterisks under the sequences, and the unique nucleotide positions of isolate A14S are shaded in black. The accession numbers of the 5S-23S rRNA intergenic spacer sequences of Borrelia strains used for comparison are L30127 (B. burgdorferi sensu stricto B31), L30119 (B. garinii 20047), L30135 (B. afzelii VS461), and L30126 (B. bissettii DN127).
