Succession of the oral microbiome with the increasing severity of periodontitis

VIEW, Volume 5, Issue 2, April 2024.
Changes in the human microbiome in the development of chronic inflammatory diseases are always an interesting scientific topic. This study focuses on the succession of oral microbiome with the increasing severity of periodontitis. The authors have applied multiple new algorithms, such as SourceTracker, site specialist, neutral community model, and ...

A public database for the new MLST scheme for Treponema pallidum subsp. pallidum: surveillance and epidemiology of the causative agent of syphilis [PDF]

PeerJ, 2019
Treponema pallidum subsp. pallidum is the causative agent of syphilis, a sexually transmitted disease with worldwide prevalence. Several different molecular typing schemes are currently available for this pathogen. To enable population biology studies of

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

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 ...

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 ...

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.

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

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 ...

Reanalysis of Chinese Treponema pallidum samples: all Chinese samples cluster with SS14-like group of syphilis-causing treponemes

BMC Research Notes, 2018
Objective Treponema pallidum subsp. pallidum (TPA) is the causative agent of syphilis. Genetic analyses of TPA reference strains and human clinical isolates have revealed two genetically distinct groups of syphilis-causing treponemes, called Nichols-like
