The Treponema pallidum Outer Membrane [PDF]

, 2017
The outer membrane (OM) of Treponema pallidum, the uncultivatable agent of venereal syphilis, has long been the subject of misconceptions and controversy. Decades ago, researchers postulated that T. pallidum's poor surface antigenicity is the basis for its ability to cause persistent infection, but they mistakenly attributed this enigmatic property to ...

Mucopolysaccharidase of Treponema pallidum [PDF]

Infection and Immunity, 1979
Treponema pallidum (Nichols strain) exhibited mucopolysaccharidase activity. Acidic mucopolysaccharides were broken down more rapidly by viable treponemes than by heat-inactivated treponemes or membrane filtrates of treponemal suspensions.

THE TREPONEMA PALLIDUM [PDF]

Archives of Internal Medicine, 1909
The discovery by Schaudinn and Hoffmann 1 in 1905 of a spirillum in various luetic lesions marked the beginning of a decided advance in our knowledge of the etiology of syphilis. The announcement of the discovery, while most conservative in its assertions, gave a fresh impetus to the study of the many phases presented in the parasitology and pathology ...
