IntroductionSyphilis is a chronic, multi-stage infection caused by the extracellular bacterium Treponema pallidum ssp. pallidum. Treponema pallidum widely disseminates through the vasculature, crosses endothelial, blood–brain and placental barriers, and ...

Mucopolysaccharidase of Treponema pallidum [PDF]
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.

Phylogenetic analysis of pbp genes in treponemes [PDF]
Background: β-Lactamases are the main cause of bacterial resistance to penicillin, cephalosporins, and related β-lactam compounds. The presence of the novel penicillin-binding protein (pbp) Tp47 in Treponema pallidum has been reported to be

Notes on syphilis vaccine development
The quest for a syphilis vaccine to provide protection from infection or disease began not long after the isolation of the first Treponema pallidum subspecies pallidum (T. pallidum) strain in 1912.

Two Potential Syphilis Vaccine Candidates Inhibit Dissemination of Treponema pallidum
Syphilis, caused by the spirochete Treponema pallidum subspecies pallidum, continues to be a major public health problem worldwide. Recent increases in the number of syphilis cases, in addition to the lack of an efficient vaccine against T.

Hybrid cell lines producing monoclonal antibodies directed against Treponema [PDF]
Continuous hybrid cell lines for producing monoclonal antibodies directed against antigens of Treponema pallidum have been developed. The hybrid cell lines were established by fusing differentiated lymphoid cells primed with antigens of Treponema ...

Yaws is a non-venereal endemic treponemal infection caused by Treponema pallidum sub-species pertenue, a spirochaete bacterium closely related to Treponema pallidum ssp. pallidum, the agent of venereal syphilis.

Background Syphilis is a multistage disease transmitted primarily through sexual intercourse. Nowadays, the polymerase chain reaction (PCR) test for Treponema pallidum has been widely used and is expected to overcome problems in diagnostic tests for ...
