Abstract

We examined the genetic characteristics of a human oral treponeme isolated from subgingival plaque of a patient with periodontal disease that could not be assigned to any of the previously described oral Treponema species. The guanine-plus-cytosine content of its DNA was 51 mole%. The levels of DNA-DNA relatedness of the organism to other Treponema species, including Treponema denticola, Treponema vincentii, Treponema socranskii, Treponema pallidum and Treponema phagedenis, were less than 30%. This study clearly demonstrated that the isolated treponeme could be completely distinct from the established oral Treponema species genetically. Also, the study indicated remarkable genetic heterogeneity among human oral Treponema species.
