A METHOD FOR CULTIVATING TREPONEMA PALLIDUM IN FLUID MEDIA.
1. A method is described for obtaining pure cultures of Treponema pallidum and allied species of spirochaetae in fluid media. 2. The principle of the method is based upon the superposition of a favorable culture medium upon a less favorable one. 3.
