Hemagglutination treponemal test for syphilis [PDF]

Journal of Clinical Microbiology, 1983
Sera from 290 hospital patients were tested to compare the sensitivity, specificity, and reproducibility of the hemagglutination treponemal test for syphilis (HATTS) with the fluorescent treponemal antibody absorption test (FTA-ABS). Complete agreement was obtained between the methods when 142 syphilitic sera from patients with various stages of ...

gen. nov. sp. nov. indicate that termite gut treponemes evolved from non‐acetogenic spirochetes in cockroaches [PDF]

, 2021
Spirochetes of the genus Treponema are surprisingly abundant in termite guts, where they play an important role in reductive acetogenesis. Although they occur in all termites investigated, their evolutionary origin is obscure. Here, we isolated the first

An Uncommon Manifestation of a Great Imitator: Gummatous Syphilis of the Liver in an HIV‐Positive Patient

Case Reports in Infectious Diseases, Volume 2024, Issue 1, 2024.
Syphilis is a sexually transmitted infection caused by Treponema pallidum. It progresses in phases and undiagnosed disease can cause considerable morbidity. Tertiary syphilis causes the formation of gummas. Liver involvement is rarely described and usually limited to transaminase elevation during primary syphilis. We present a case of tertiary syphilis

Beyond appearance: An unusual manifestation of isolated oral secondary syphilis

International Journal of Immunopathology and Pharmacology, 2019
Syphilis is a sexually acquired chronic infection caused by Treponema pallidum and is characterized by a variety of clinical manifestations. The secondary stage of the disease results from the hematogenous and lymphatic dissemination of treponemes after ...

Fatty acids synthesized by oral treponemes in chemically defined media [PDF]

, 2007
OMIZ-W68, a chemically defined medium that contains no long-chain fatty acids and yet supports in vitro proliferation of a wide range of fastidious oral anaerobes, is described.

Two paralogous families of a two-gene subtilisin operon are widely distributed in oral treponemes. [PDF]

, 2003
Certain oral treponemes express a highly proteolytic phenotype and have been associated with periodontal diseases. The periodontal pathogen Treponema denticola produces dentilisin, a serine protease of the subtilisin family. The two-gene operon prcA-prtP

Identification of positively selected genes in human pathogenic treponemes: Syphilis-, yaws-, and bejel-causing strains differ in sets of genes showing adaptive evolution.

PLoS Neglected Tropical Diseases, 2019
BackgroundPathogenic treponemes related to Treponema pallidum are both human (causing syphilis, yaws, bejel) and animal pathogens (infections of primates, venereal spirochetosis in rabbits). A set of 11 treponemal genome sequences including those of five

Diagnostic capabilities of non-treponemal and treponemal reactions in the early forms of syphilis.

Medicni perspektivi (Medical perspectives), 2017
A comparative analysis of the sensitivity and specificity of immunoblotting against other non-treponemal and treponemal reactions was carried out in 215 patients with early forms of syphilis. A high diagnostic efficiency of immunoblotting in patients with early latent syphilis was established.

A Metataxonomic Tool to Investigate the Diversity of Treponema

Frontiers in Microbiology, 2019
The genus Treponema contains a number of human and animal pathogenic as well as symbiotic bacteria that are found in vastly different anatomical and environmental habitats. Our understanding of the species range, evolution, and biology of these important

Genome analysis of Treponema pallidum subsp. pallidum and subsp. pertenue strains: most of the genetic differences are localized in six regions.

PLoS ONE, 2010
The genomes of eight treponemes including T. p. pallidum strains (Nichols, SS14, DAL-1 and Mexico A), T. p. pertenue strains (Samoa D, CDC-2 and Gauthier), and the Fribourg-Blanc isolate, were amplified in 133 overlapping amplicons, and the restriction ...
