Fifteen oral spirochete strains belonging to the species Treponema denticola, Treponema vencentii and Treponema socranskii as well as 9 fresh clinical isolates were screened for the presence of extrachromosomal plasmid DNA by a modified alkaline lysis procedure. A 2.6-kb plasmid was detected in both T. denticola ATCC 33520 and T. denticola e'. The 2.6-kb plasmid from T. denticola e' was shown to be similar to pTD1, previously reported by Ivic et al. in T. denticola ATCC 33520 on the basis of molecular weight, restriction endonuclease profile and DNA:DNA hybridization. T. denticola ATCC 33520 and T. denticola e' share 65% DNA homology and belong to different serological groups. This dissimilarity has been reconfirmed by specific immunofluorescence using polyclonal and monoclonal antibodies. A plasmid-free T. denticola ATCC 33520 was identified. Comparative studies have shown no antigenic, morphological, or genetic differences between the plasmid-bearing and the plasmid-free strain. In addition, screening of fresh clinical isolates of spirochetes revealed the presence of a 4.2-kb plasmid in 4 of these strains.
