Multilocus sequence analysis of phylogroup 1 and 2 oral treponeme strains [PDF]

, 2017
More than 75 ‘species-level' phylotypes of spirochete bacteria belonging to the genus Treponema reside within the human oral cavity. The majority of these oral treponeme phylotypes correspond to as-yet uncultivated taxa, or strains of uncertain standing ...

Isolation of a chymotrypsinlike enzyme from Treponema denticola [PDF]

Infection and Immunity, 1988
A chymotrypsinlike protease with an Mr of 95,000 was extracted from Treponema denticola ATCC 35405 and was partially purified by preparative sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The proteolytic activity was detected in an electrophoretogram containing polyacrylamide that was conjugated to bovine serum albumin.

Periodontal pathogens promote cancer aggressivity via TLR/MyD88 triggered activation of Integrin/FAK signaling that is therapeutically reversible by a probiotic bacteriocin.

PLoS Pathogens, 2020
Epidemiological studies reveal significant associations between periodontitis and oral cancer. However, knowledge about the contribution of periodontal pathogens to oral cancer and potential regulatory mechanisms involved is limited.

Porphyromonas gingivalis and Treponema denticola exhibit metabolic symbioses. [PDF]

PLoS Pathogens, 2014
Porphyromonas gingivalis and Treponema denticola are strongly associated with chronic periodontitis. These bacteria have been co-localized in subgingival plaque and demonstrated to exhibit symbiosis in growth in vitro and synergistic virulence upon co ...

Polymicrobial periodontal disease triggers a wide radius of effect and unique virome. [PDF]

, 2020
Periodontal disease is a microbially-mediated inflammatory disease of tooth-supporting tissues that leads to bone and tissue loss around teeth. Although bacterially-mediated mechanisms of alveolar bone destruction have been widely studied, the effects of

Multilocus sequence analysis of Treponema denticola strains of diverse origin

BMC Microbiology, 2013
Background The oral spirochete bacterium Treponema denticola is associated with both the incidence and severity of periodontal disease. Although the biological or phenotypic properties of a significant number of T.

Active invasion of Porphyromonas gingivalis and infection-induced complement activation in ApoE-/- mice brains [PDF]

, 2014
Periodontal disease is a polymicrobial inflammatory disease that leads to chronic systemic inflammation and direct infiltration of bacteria/bacterial components, which may contribute to the development of Alzheimer’s disease.

Detection of Treponema denticola in Atherosclerotic Lesions [PDF]

Journal 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 ...
