Quorum Sensing Regulation in Phytopathogenic Bacteria
Microorganisms, 2021 Quorum sensing is a type of chemical communication by which bacterial populations control expression of their genes in a coordinated manner. This regulatory mechanism is commonly used by pathogens to control the expression of genes encoding virulence ...

Quorum-Sensing Regulation of Antimicrobial Resistance in Bacteria
Microorganisms, 2020 Quorum sensing is a cell-to-cell communication system that exists widely in the microbiome and is related to cell density. The high-density colony population can generate a sufficient number of small molecule signals, activate a variety of downstream ...

Breaking down bacterial communication: a review of quorum quenching agents
Future Journal of Pharmaceutical Sciences, 2023 Background Bacterial cells communicate via small extracellular molecules that facilitate gene expression which is dependent on cell density and this mechanism is known as Quorum Sensing (QS).

iScience, 2023 The first discovered and well-characterized bacterial quorum sensing (QS) system belongs to Vibrio fischeri, which uses N-acyl homo-serine lactones (AHLs) for cell-cell signaling. AHL QS cell-cell communication is often regarded as a cell density-dependent regulatory switch.

Frontiers in Microbiology, 2020 A biofilm is an assemblage of microbial cells attached to a surface and encapsulated in an extracellular polymeric substance (EPS) matrix. The formation of a biofilm is one of the important mechanisms of bacterial resistance, which not only leads to hard-

Quorum sensing as a mechanism to harness the wisdom of the crowds
Nature Communications, 2023 Bacteria release and sense small molecules called autoinducers in a process known as quorum sensing. The prevailing interpretation of quorum sensing is that by sensing autoinducer concentrations, bacteria estimate population density to regulate the ...

Quorum‐sensing system in Acinetobacter baumannii: a potential target for new drug development
Journal of Applied Microbiology, 2020 Acinetobacter baumannii causes several nosocomial infections and poses major threat when it is multidrug resistant. Even pan drug‐resistant strains have been reported in some countries. The intensive care unit (ICU) mortality rate ranged from 45.6% to 60.

Quorum Sensing of Periodontal Pathogens
Acta Stomatologica Croatica, 2015 The term ‘quorum sensing’ describes intercellular bacterial communication which regulates bacterial gene expression according to population cell density. Bacteria produce and secrete small molecules, named autoinducers, into the intercellular space.
