Research progress on the structure and function of the type IX secretion system of Porphyromonas gingivalis

口腔疾病防治, 2023
The Porphyromonas gingivalis type IX secretion system (T9SS) is a recently discovered protein secretion system that is widely distributed in Bacillus cereus. The T9SS is structurally complex and powerful.

Development of antiseptic adaptation and cross-adapatation in selected oral pathogens in vitro [PDF]

, 2019
There is evidence that pathogenic bacteria can adapt to antiseptics upon repeated exposure. More alarming is the concomitant increase in antibiotic resistance that has been described for some pathogens.

In vitro increased respiratory activity of selected oral bacteria may explain competitive and collaborative interactions in the oral microbiome [PDF]

, 2017
Understanding the driving forces behind the shifts in the ecological balance of the oral microbiota will become essential for the future management and treatment of periodontitis. As the use of competitive approaches for modulating bacterial outgrowth is

Gingipain aminopeptidase activities in Porphyromonas gingivalis [PDF]

bchm, 2012
Abstract Bestatin, a specific inhibitor of metalloaminopeptidases, inhibits the growth of Porphyromonas gingivalis. To identify its target enzyme, a library of fluorescent substrates was used but no metalloaminopeptidase activity was found. The aminopeptidase activity of P.

Porphyromonas Gingivalis Sialidase Reshapes Gut Microbiota And Systemic Immunity

International Dental Journal
Aim or purpose: Porphyromonas gingivalis can alter the gut microbiota and serum metabolites. However, its sialidase in modulating gut microbiota composition, host metabolism, and immune responses remains unexplored.

Hemin availability induces coordinated DNA methylation and gene expression changes in Porphyromonas gingivalis

mSystems, 2023
Periodontal disease is a chronic inflammatory disease in which the oral pathogen Porphyromonas gingivalis plays an important role. Porphyromonas gingivalis expresses virulence determinants in response to higher hemin concentrations, but the underlying ...

Novel fimbrilin PGN_1808 in Porphyromonas gingivalis

PLOS ONE, 2017
Porphyromonas gingivalis, a periodontopathic gram-negative anaerobic bacterium, generally expresses two types of fimbriae, FimA and Mfa1. However, a novel potential fimbrilin, PGN_1808, in P. gingivalis strain ATCC 33277 was recently identified by an in silico structural homology search.
