title: In vitro cultivation of Treponema pallidum: independent confirmation.
abstract: In vitro cultivation of the virulent Nichols strain of Treponema pallidum was achieved in a tissue culture system as described by A. H. Fieldsteel, D. L. Cox, and R. A. Moeckli (Infect. Immun. 32:908-915, 1981). In 7 of 8 experiments, 8.9- to 26.2-fold increases in the number of T. pallidum were observed over a 12- to 12-day period of incubation.
