Exploiting quorum sensing interfering strategies in gram-negative bacteria for the enhancement of environmental applications [PDF]
Frontiers in Microbiology, 2016 Quorum sensing (QS) is a widespread intercellular form of communication to coordinate physiological processes and cooperative activities of bacteria at the population level, and it depends on the production, secretion, and detection of small diffusible ...

A Comprehensive Review of the Multitarget Effects of Subinhibitory Concentrations of Essential Oils Against Salmonella. [PDF]
Compr Rev Food Sci Food SafABSTRACT Essential oils (EOs) exhibit antimicrobial activity against foodborne pathogens due to their chemical composition. This review investigates the mechanisms of action of EOs at subinhibitory concentrations against Salmonella strains. Even at subinhibitory concentrations, EOs induce cellular stress and modulate bacterial metabolism. EOs interfere

The Autoinducer-2 Exporter Superfamily [PDF]
Microbial Physiology, 2010 The TqsA (YdgG) protein of <i>Escherichia coli</i> has been shown to export the autoinducer-2 (AI-2) molecule, a furanosyl borate diester that bears little resemblance to previously characterized biological molecules. TqsA belongs to a large superfamily, the AI-2 exporter (AI-2E) superfamily, of putative transporters with no other ...

Quorum sensing in Vibrio fischeri: probing autoinducer-LuxR interactions with autoinducer analogs [PDF]
Journal of Bacteriology, 1996 The Vibrio fischeri luminescence genes are activated by the transcription factor LuxR in combination with a diffusible signal compound, N-(3-oxohexanoyl) homoserine lactone, termed the autoinducer. We have synthesized a set of autoinducer analogs. Many analogs with alterations in the acyl side chain showed evidence of binding to LuxR.

Quorum Sensing Interfering Strategies and Their Implications in the Management of Biofilm-Associated Bacterial Infections [PDF]
Brazilian Archives of Biology and Technology, 2020 The bacterial species employ various types of molecular communication systems recognized as quorum sensing for the synchronization of differential gene expression to regulate virulence traits and biofilm formation. A variety of quorum sensing inhibitors;

Core Principles of Bacterial Autoinducer Systems [PDF]
Microbiology and Molecular Biology Reviews, 2015 SUMMARY Autoinduction (AI), the response to self-produced chemical signals, is widespread in the bacterial world. This process controls vastly different target functions, such as luminescence, nutrient acquisition, and biofilm formation, in different ways and integrates additional environmental and physiological cues.

Bacterial Quorum-Sensing Systems and Their Role in Intestinal Bacteria-Host Crosstalk
Frontiers in Microbiology, 2021 Quorum-sensing (QS) system is a rapidly developing field in which we are gradually expanding our understanding about how bacteria communicate with each other and regulate their activities in bacterial sociality.
