Treponema denticola: patógeno en procesos periodontales y pulpares

Odontología Sanmarquina, 2012
En la etiología multifactorial de la enfermedad periodontal y procesos pulpares, el factor bacteriano tiene gran relevancia. En estos procesos se identifica una flora polimicrobiana en la que destaca Treponema denticola, una espiroqueta con múltiples ...

Structure and Mechanism of Ergothionase from Treponema denticola [PDF]

Chemistry – A European Journal, 2019
AbstractErgothioneine is a sulfur‐containing histidine derivative that emerges from microbial biosynthesis and enters the human body through intestinal uptake and regulated distribution into specific tissues. Although the proteins involved in biosynthesis and uptake are well characterized, less is known about the degradative pathways of ergothioneine ...

MICROORGANISMOS EN ENFERMEDAD PERIODONTAL

Revista Científica Universidad Odontológica Dominicana, 2023
Introducción: Cuando existe un desequilibrio en el huésped, se ha demostrado que hay microorganismos que contribuyen a la formación de distintas periodontopatías, siendo considerados como principales microorganismos los del complejo rojo de Socransky ...

Estimation of bacterial hydrogen sulfide production in vitro

Journal of Oral Microbiology, 2015
Oral bacterial hydrogen sulfide (H2S) production was estimated comparing two different colorimetric methods in microtiter plate format. High H2S production was seen for Fusobacterium spp., Treponema denticola, and Prevotella tannerae, associated with ...

Nisin bacteriocin blocks T. denticola-triggered MMP2 activation and pathogen internalization via TLR2

Scientific Reports
We examined Treponema denticola-induced dysregulation of toll-like receptor (TLR) signaling and its downstream effects on matrix metalloproteinase 2 (MMP2) expression and activation in periodontal cells, and whether the antimicrobial peptide nisin could ...

Intracellular localization of Treponema denticola chymotrypsin-like proteinase in chronic periodontitis

Journal of Oral Microbiology, 2014
Treponema denticola is an important periodontal pathogen capable of tissue invasion. Its chymotrypsin-like proteinase (CTLP) can degrade a number of basement membrane components in vitro, thus suggesting a contribution to tissue invasion by the ...

Isolation and characterization of a plasmid fromTreponema denticola

FEMS Microbiology Letters, 1991
Agarose gel electrophoresis of whole genomic DNA of the oral spirochaete Treponema denticola has revealed a plasmid-like fraction. Purification and restriction enzyme analysis has confirmed the presence of a 2.6-kb circular plasmid, which has been mapped for restriction sites and cloned into the Escherichia coli plasmid pUC18. Southern blot analysis of

Killing of Treponema denticola by Mouse Peritoneal Macrophages

Journal of Dental Research, 2010
Treponema denticola has been identified as an important cause of periodontal disease and hypothesized to be involved in extra-oral infections. The objective of this study was to investigate the role of T. denticola cell length and motility during mouse peritoneal macrophages in vitro uptake. Macrophages, incubated under aerobic and anaerobic conditions,

An investigation of the presence of specific anaerobic species in necrotic primary teeth

Brazilian Oral Research, 2013
Different microbial identification methods have shown that the microbial community profiles in endodontic infections are diverse and assorted. The aim of this study was to evaluate the frequency of selected endodontic pathogens in the pulp chambers (PCs)

Red-complex bacteria: immunological background leading to the development of head and neck cancers

Frontiers in Immunology
Oral microbiome imbalance is involved in the development of head and neck cancers (HNCs). There is a group of oral pathogens, such as Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, that creates red-complex.
