The Microbial Aetiology of Periodontal Diseases [PDF]

open access: yes, 2012
Introduction: The study of the aetiology of periodontal diseases has continued for decades with much progress shown in the last two decades. Having moved through periods of “whole” plaque (with emphasis on mass) being attributed to the disease process,

Detection of Treponema denticola in Atherosclerotic Lesions [PDF]

open access: yesJournal of Clinical Microbiology, 2001
ABSTRACT We examined 26 atherosclerotic lesions and 14 nondiseased aorta specimens to detect the periodontopathogenic part of the bacterial 16S rRNA locus by PCR. Treponema denticola sequence of the 16S rRNA locus was found in 6 out of 26 DNA samples (23.1%) from the formalin-fixed, paraffin-embeded ...

Treponema denticola: A teammate in periodontal progression

open access: yesJournal of International Clinical Dental Research Organization, 2016
There is compelling evidence that treponemes are involved in the etiology of several chronic oral diseases, including chronic periodontitis and other forms of periodontal disease.

Detection of Red complex bacteria, P. gingivalis, T. denticola and T. forsythia in infected root canals and their association with clinical signs and symptoms

open access: yesJournal of Family Medicine and Primary Care, 2020
Aim: This study aimed to investigate the association between endodontic clinical signs and symptoms and the presence of Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia employing polymerase chain reaction (PCR).

Characterization of Treponema phagedenis-like spirochetes isolated from papillomatous digital dermatitis lesions in dairy cattle [PDF]

open access: yes, 2003
Four spirochete strains were isolated from papillomatous digital dermatitis (PDD) lesions in Iowa dairy cattle and compared with two previously described spirochete strains isolated from dairy cattle in California.

Inhibitory effect of Streptococcus salivarius K12 and M18 on halitosis in vitro

open access: yesClinical and Experimental Dental Research, 2020
Background The aim of the study was to observe the antimicrobial activity of Porphyromonas gingivalis and Treponema denticola as well as the effect on reducing volatile sulfur compounds (VSCs). Materials and methods After P. gingivalis and T.

Advancement of the 10-species subgingival Zurich Biofilm model by examining different nutritional conditions and defining the structure of the in vitro biofilms [PDF]

open access: yes, 2012
BACKGROUND: Periodontitis is caused by a highly complex consortium of bacteria that establishes as biofilms in subgingival pockets. It is a disease that occurs worldwide and its consequences are a major health concern.

Physical map of the Treponema denticola circular chromosome [PDF]

open access: yesJournal of Bacteriology, 1995
A physical map of the Treponema denticola ATCC 33520 genome was constructed by pulsed-field gel electrophoresis and DNA hybridization. The organism possesses a single, circular chromosome of approximately 3.0 Mbp and a 2.6-kbp circular plasmid, pTD1. The physical map of the A+T-rich genome was constructed with the rare-cutting restriction enzymes AscI,

Porphyromonas gingivalis and Treponema denticola synergistic polymicrobial biofilm development. [PDF]

open access: yesPLoS ONE, 2013
Chronic periodontitis has a polymicrobial biofilm aetiology and interactions between key bacterial species are strongly implicated as contributing to disease progression.

Native cellular architecture of Treponema denticola revealed by cryo-electron tomography [PDF]

open access: yes, 2009
Using cryo-electron tomography, we are developing a refined description of native cellular structures in the pathogenic spirochete Treponema denticola. Tightly organized bundles of periplasmic flagella were readily observed in intact plunge-frozen cells.
