title: [Study of the plasmid composition of various strains of Treponema pallidum].
abstract: Plasmid DNA has been isolated by soft alkaline and hard alkaline lysis from a pathogenic strain (Nichols) and two cultural strains (Reiter and VIII) of Treponema pallidum. Plasmid DNA was identified in all three strains. The molecular mass of identified plasmid DNA is 7 x 10(6) daltons according to the data of electrophoretic analysis in the agarose gel.
