Optimal Census by Quorum Sensing
PLOS Computational Biology, 2015 Quorum sensing is the regulation of gene expression in response to changes in cell density. To measure their cell density, bacterial populations produce and detect diffusible molecules called autoinducers. Individual bacteria internally represent the external concentration of autoinducers via the level of monitor proteins.

Quorum sensing inSerratia [PDF]
FEMS Microbiology Reviews, 2007 Many bacteria use cell-cell communication to monitor their population density, synchronize their behaviour and socially interact. This communication results in a coordinated gene regulation and is generally called quorum sensing. In gram-negative bacteria, the most common quorum signal molecules are acylated homoserine lactones (AHLs), although other ...

Inhibition of Pseudomonas aeruginosa Quorum Sensing by Curcuma xanthorrhiza Roxb. Extract
Journal of Pure and Applied Microbiology, 2019 Microorganisms such as Pseudomonas aeruginosa have always been adaptable in surviving the harsh environment such as antimicrobial agents via the quorum sensing (QS) mechanism.

Transcriptome analysis of acyl-homoserine lactone-based quorum sensing regulation in Yersinia pestis [corrected]. [PDF]
PLoS ONE, 2013 The etiologic agent of bubonic plague, Yersinia pestis, senses self-produced, secreted chemical signals in a process named quorum sensing. Though the closely related enteric pathogen Y.

Stochastic Effects in Quorum Sensing [PDF]
, 2014 [cat] En aquesta tesi, estudiem els efectes de la estocàsticitat en la aparició del comportament col·lectiu en poblacions de bacteris que comuniquen per quorum sensing (QS). Ens centrem en el interruptor genètic com a paradigma dels processos de decisió cel·lulars tant en sistemes de bacteris naturals com sintètics.

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.

Strength in numbers? Not always!
, 2010 We propose a simple model to compute the probability of success under a quorum sensing strategy. We show that a quorum sensing strategy has a higher probability of success than an individualistic strategy when, for instance, the probability of success ...

Effects of micro-algae commonly used in aquaculture on acyl-homoserine lactone quorum sensing. [PDF]
, 2011 Quorum sensing, bacterial cell-to-cell communication with small signal molecules such as acyl-homoserine lactones, regulates the virulence of many pathogenic bacteria.

Quorum sensing in Staphylococcus infections [PDF]
Journal of Clinical Investigation, 2003 Quorum sensing via the accessory gene regulator (agr) system has been assigned a central role in the pathogenesis of staphylococci, particularly Staphylococcus aureus. While the control of virulence gene expression in vitro by agr has been relatively straightforward to describe, regulation of both the quorum response itself and virulence genes in vivo ...
