A mathematical model of quorum quenching in biofilm colonies and its potential role as an adjuvant for antibiotic treatment

open access: yesMathematics in Applied Sciences and Engineering, 2022
We extend a previously presented mesoscopic (i.e. colony scale) mathematical model of the reaction of bacterial biofilms to antibiotics. In that earlier model, exposure to antibiotics evokes two responses: inactivation as the antibiotics kill the ...

Quorum Sensing by Monocyte-Derived Populations [PDF]

open access: yesFrontiers in Immunology, 2019
Quorum sensing is a type of cellular communication that was first described in bacteria, consisting of gene expression regulation in response to changes in cell-population density. Bacteria synthesize and secrete diffusive molecules called autoinducers, which concentration varies accordingly with cell density and can be detected by the producing cells ...

Research progress on quorum sensing in the caries-causing effects of Streptococcus mutans and Candida albicans [PDF]

open access: yes口腔疾病防治
Dental caries is a major disease that seriously endangers human oral health. Dental plaque biofilm composed of many microorganisms is the primary factor of dental caries. Inhibiting biofilm formation has become the focus of research on the prevention and

Quorum-Sensing Inhibition

open access: yes, 2014
As the elucidation of the molecular mechanisms behind quorum sensing (QS) gained momentum, researchers conceived several strategies to block QS systems. Indeed, QS signals can be detected in biofilms across a range of environments. For example, biofilms grown on rocks in the San Marcos River in Texas have been shown to produce acyl-homoserine lactone ...

Lipid Nanoparticle‐Mediated CRISPR‐Cas13a Delivery for the Control of Bacterial Infection

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
New formulations of lipid nanoparticles (LNPs) that can deliver nucleic acids to Gram‐negative bacteria are proposed to combat bacterial infection. The delivery of nucleic acids by LNPs is aided by LNP‐helpers which weaken the bacterial outer membrane. LNPs encapsulating the Cas13a/gRNA expression vector achieve an antibacterial effect in both in vivo ...

Quorum sensing influences Vibrio harveyi growth rates in a manner not fully accounted for by the marker effect of bioluminescence.

open access: yesPLoS ONE, 2008
BackgroundThe light-emitting Vibrios provide excellent material for studying the interaction of cellular communication with growth rate because bioluminescence is a convenient marker for quorum sensing.

Attenuation of quorum sensing system and virulence in Vibrio cholerae by phytomolecules

open access: yesFrontiers in Microbiology, 2023
The Vibrio cholerae, a gram-negative bacterium, is the causative agent of cholera. Quorum sensing is a cell-to-cell communication that leads to gene expression, accumulation of signaling molecules, biofilm formation, and production of virulence factors ...
