Many bacteria use 'quorum sensing' (QS) as a mechanism to regulate gene induction in a population-dependent manner. In its simplest sense this involves the accumulation of a signaling metabolite during growth; the binding of this metabolite to a regulator or multiple regulators activates induction or repression of gene expression. However QS regulation

Quorum-sensing signals are found in many species of legume-nodulating rhizobia. In a well-characterized strain of R. leguminosarum biovar viciae, a variety of autoinducers are synthesised, and all have been identified as N-acyl-homoserine lactones.

Annual Review of Microbiology, 2001
▪ Abstract Quorum sensing is the regulation of gene expression in response to fluctuations in cell-population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell density.

Farnesol and Candida albicans: Quorum Sensing or Not Quorum Sensing?
Israel Journal of Chemistry, 2015AbstractQuorum sensing (QS) molecules function within communities of single‐cell organisms to allow concerted behavior in response to changing conditions, and certain criteria have been established to determine whether a particular molecule is quorum sensing or not.

Quorum Sensing in Staphylococci
Annual Review of Genetics, 2008The staphylococcal agr locus encodes a quorum sensing (QS) system that controls the expression of virulence and other accessory genes by a classical two-component signaling module. Like QS modalities in other Gram-positive bacteria, agr encodes an autoactivating peptide (AIP) that is the inducing ligand for AgrC, the agr signal receptor.

Quorum sensing of pathogenic bacteria and quorum-sensing inhibitors
Chinese Science Bulletin, 2012The emergence of antibiotic-resistant and especially multidrug-resistant pathogenic bacteria intensifies the need to screen new drug targets and develop new antibacterial drugs. Bacteria coordinate their virulent behaviors in a cell density-dependent manner known as quorum sensing (QS).

Mechanisms of quorum sensing and strategies for quorum sensing disruption in aquaculture pathogens
Journal of Fish Diseases, 2014AbstractIn many countries, infectious diseases are a considerable threat to aquaculture. The pathogenicity of micro‐organisms that infect aquaculture systems is closely related to the release of virulence factors and the formation of biofilms, both of which are regulated by quorum sensing (QS). Thus, QS disruption is a potential strategy for preventing

Quorum Sensing in Extremophiles
2019Extremophiles represent a heterogeneous class of organisms that inhabit environments characterized by atypical parameters (high or low temperatures/pH/salinity, etc.). These organisms not only adapt to these habitats, but the exceptional environmental characteristics ensure their optimal growth. The environmental adaptation of extremophiles has been of

Acne, quorum sensing and danger
Clinical and Experimental Dermatology, 2014Propionibacterium acnes is a ubiquitous skin commensal bacterium, which is normally well tolerated by the immune system in healthy human skin. However, there is increasing evidence to suggest a pivotal role for P. acnes in the inflammatory process underlying the acne pathogenesis.
