What Is Quorum Sensing? Individual bacteria use quorum sensing to detect and respond to changes in cell density as a coordinated group. For example, the first reported evidence of quorum sensing was ...

Quorum sensing is essential for the virulence of several bacterial pathogens, and antagonists of this process are currently being investigated as potential therapeutics. Bassler and colleagues now ...

Bacterial Quorum Sensing: A Matter Of Density, Not Quantity Date: July 21, 2009 Source: Wiley-Blackwell Summary: Researchers have demonstrated that the absolute number of cells is irrelevant to ...

Quorum sensing also crosses the prokaryotic-eukaryotic boundary since quorum sensing-dependent signalling can be exploited or inactivated by both plants and mammals. Journal Information. From the ...

Bacterial Quorum Sensing and Metabolic Incentives to Cooperate. Science , 12 October 2012: Vol. 338 no. 6104 pp. 264-266 DOI: 10.1126/science.1227289 Cite This Page : ...

Blocking quorum sensing can prevent group attacks from bacteria without having to selectively kill bacteria cells. Blackwell said Ma has been a valuable asset to the team from early on. Ma has ...

Quorum Sensing in Vibrio cholerae. Quorum signaling is controlled by two opposing pathways: the CqsS/CqsA pathway (produces and detects CAI-1), and the LuxS/LuxPQ pathway (produces and detects AI-2).

Quorum sensing involves the regulation of the expression of genes within the DNA of the bacterium, which is controlled by the cell-population density of the extracellular environment, or biofilm.

P. aeruginosa possesses similar quorum-sensing machinery to other species of bacteria. For example, it produces an enzyme called RhlI that synthesizes an autoinducer molecule known as N-butanoyl-L ...
