Fsr quorum sensing system modulates the temporal development of Enterococcus faecalis biofilm matrix.

Molecular oral microbiology

Ali IAA, Lévesque CM, Neelakantan P.
PMID: 34862746
Mol Oral Microbiol. 2022 Feb;37(1):22-30. doi: 10.1111/omi.12357. Epub 2021 Dec 15.

Quorum sensing (QS) is a cell-to-cell communication process that regulates major pathogenic attributes in bacteria including biofilm formation, secretion of virulence factors, and antimicrobial resistance. The two-component Fsr-QS system of the nosocomial pathogen Enterococcus faecalis controls the production of...

Porphyromonas gingivalis indirectly elicits intestinal inflammation by altering the gut microbiota and disrupting epithelial barrier function through IL9-producing CD4.

Molecular oral microbiology

PMID: 34958712
Mol Oral Microbiol. 2021 Dec 27; doi: 10.1111/omi.12359. Epub 2021 Dec 27.

BACKGROUND: Recent epidemiological studies have shown that inflammatory bowel disease is associated with periodontal disease. The oral-gut microbiota axis is a potential mechanism intersecting the two diseases. Porphyromonas gingivalis is currently considered a keystone oral pathogen involved in periodontal...

Spermidine enhances the survival of Streptococcus pyogenes M3 under oxidative stress.

Mol Oral Microbiol. 2022 Jan 06; doi: 10.1111/omi.12360. Epub 2022 Jan 06.

Streptococcus pyogenes, a host-restricted gram-positive pathogen during infection, initially adheres to the epithelia of the nasopharynx and respiratory tract of the human host, followed by disseminating to other organs and evading the host immune system. Upon phagocytosis, S. pyogenes...

Sublingual immunization with recombinant GroEL plus CpG-ODN inhibits Porphyromonas gingivalis-induced inflammation and alveolar bone loss.

Molecular oral microbiology

Mol Oral Microbiol. 2021 Dec 17; doi: 10.1111/omi.12358. Epub 2021 Dec 17.

It has been reported that GroEL, a heat shock protein (HSP) produced by the representative periodontopathogenic bacterium, Porphyromonas gingivalis, induces inflammation-induced osteoclastogenesis and promotes alveolar bone resorption. In this study, we demonstrated the efficacy of a mucosal vaccine targeting...

Mol Oral Microbiol. 2021 Nov 11; doi: 10.1111/omi.12356. Epub 2021 Nov 11.

Diadenosine-5',5'''-P1, P4-tetraphosphate (Ap4A) is a second messenger playing a crucial role in various life activities of bacteria. The increase of Ap4A expression is pleiotropic, resulting in an impairment in the formation of biofilm and other physiological functions in some...

Strategies for Streptococcus mutans biofilm dispersal through extracellular polymeric substances disruption.

Molecular oral microbiology

PMID: 34727414
Mol Oral Microbiol. 2022 Feb;37(1):1-8. doi: 10.1111/omi.12355. Epub 2021 Nov 22.

Dental caries is one of the most prevalent and costly biofilm-dependent oral infectious diseases affecting most of the world's population. Streptococcus mutans, a major extracellular polymeric substance (EPS) producing bacteria in dental plaque, plays a vital role in human...
