Attenuation of Pseudomonas aeruginosa Virulence by Pomegranate Peel Extract
Microorganisms, 2022 Pseudomonas aeruginosa is an opportunistic pathogen often responsible for biofilm-associated infections. The high adhesion of bacterial cells onto biotic/abiotic surfaces is followed by production of an extracellular polysaccharidic matrix and formation ...

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;

The Lantibiotic Mersacidin Is an Autoinducing Peptide [PDF]
Applied and Environmental Microbiology, 2006 ABSTRACT The lantibiotic (lanthionine-containing antibiotic) mersacidin is an antimicrobial peptide consisting of 20 amino acids and is produced by Bacillus sp. strain HIL Y-85,54728. The structural gene ( mrsA ) and the genes for producer self-protection, modification enzymes ...

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.

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.

Spatial Heterogeneity of Autoinducer Regulation Systems [PDF]
Sensors, 2012 Autoinducer signals enable coordinated behaviour of bacterial populations, a phenomenon originally described as quorum sensing. Autoinducer systems are often controlled by environmental substances as nutrients or secondary metabolites (signals) from neighbouring organisms.
