The intriguing strategies of Tannerella forsythia's host interaction

Frontiers in Oral Health
Tannerella forsythia, a member of the “red complex” bacteria implicated in severe periodontitis, employs various survival strategies and virulence factors to interact with the host. It thrives as a late colonizer in the oral biofilm, relying on its unique adaptation mechanisms for persistence.

Isolation and identification of a cytopathic activity in Tannerella forsythia

Biochemical and Biophysical Research Communications, 2006
Interactions between pathogens and host induce human disorders including periodontitis, disintegration of the tooth supporting tissues. Tannerella forsythia has been linked to the periodontitis and several cytopathic reagents have been found in the bacterium; however, its contribution to the disease remains unclear.

Collagenolytic activity in sonic extracts of Tannerella forsythia

Archives of Oral Biology, 2010
The purpose of the present study was to characterize the collagenolytic activity in a sonicated extract of Tannerella forsythia and to investigate the activation of proMMMP-2 and -9 by the T. forsythia extract.The T. forsythia extract was incubated with type I collagen. The cleaved products were then analyzed by SDS-PAGE using the method of Laemmli. We

Construction of a Gene-Deletion Mutant in Tannerella forsythia

2020
Tannerella forsythia, a gram-negative anaerobic bacterium, is one of the most important pathogens in periodontal disease. However, it has been difficult to construct a gene-deletion mutant in this organism, which may serve as a useful tool in microbiological research.

The distribution of Tannerella forsythia in an adolescent and adult population

Journal of Periodontal Research, 2005
Background:  The fact that Tannerella forsythia, an important periopathogen, is difficult to cultivate from mixed infections has impeded precise estimates of its distribution within a given population. In order to discern T. forsythia alone from the mixed infection of plaque, the use of sensitive 16S ribosomal RNA based polymerase chain reaction (PCR ...

Pathogenic potential of Tannerella forsythia enolase

Molecular Oral Microbiology, 2015
SummaryAlthough enolases are cytosolic enzymes involved in the glycolytic pathway, they can also be secreted or expressed on the surface of a variety of eukaryotic cells and bacteria. Surface‐exposed enolases of eukaryotes and bacteria can function as plasminogen receptors.

Outer Membrane Proteome and Antigens of Tannerella forsythia

Journal of Proteome Research, 2009
Tannerella forsythia is a Gram-negative, anaerobic, fusiform bacterium implicated as a periodontal pathogen. With use of 2D PAGE, SDS PAGE, and LC-MALDI-TOF/TOF MS, 221 proteins of T. forsythia outer membrane preparations were identified, of which 197 were predicted to be localized to the cell envelope. Fifty-six proteins were reproducibly mapped by 2D

A simple mutagenesis using natural competence in Tannerella forsythia

Journal of Microbiological Methods, 2013
We report the discovery of natural competence in Tannerella forsythia and its application to targeted chromosomal mutagenesis. Keeping T. forsythia in a biofilm throughout the procedure allowed efficient DNA uptake and allelic replacement. This simple method is cost-effective and reproducible compared with the conventional protocols using broth culture

Reducing the bioactivity of Tannerella forsythia lipopolysaccharide by Porphyromonas gingivalis

Journal of Microbiology, 2014
Tannerella forsythia is considered a pathogen of periodontitis and forms a biofilm with multi-species bacteria in oral cavity. Lipopolysaccharide is a powerful immunostimulator and induces inflammation and shock. The purpose of this study was to investigate the characteristics of T.

Analysis of the cell surface layer ultrastructure of the oral pathogen Tannerella forsythia [PDF]

Archives of Microbiology, 2012
The Gram-negative oral pathogen Tannerella forsythia is decorated with a 2D crystalline surface (S-) layer, with two different S-layer glycoprotein species being present. Prompted by the predicted virulence potential of the S-layer, this study focused on the analysis of the arrangement of the individual S-layer glycoproteins by a combination of ...
