*Boldface indicates differences in nucleotide sequences. BsrDI restriction sites are underlined.
†Sequences were obtained from GenBank: Bosnia A (T. pallidum subsp. endemicum), Samoa D (T. pallidum subsp. pertenue) and syphilis control strain Nichols (T. pallidum subsp. pallidum).
‡Sequence also confirmed in this study.
