Quorum Sensing in Microbial Virulence
Cell-to cell communication occurs via a signaling pathway referred to as quorum sensing. There are four main types of these systems according to the chemical nature of signal molecules used by microorganisms to elicit expression of target genes in response to environmental stimuli or need of microbial communities. Type I system acts by using acyl homoserine lactones as signals to trigger the ex...
متن کاملIs quorum sensing a side effect of diffusion sensing?
Many bacteria appear to communicate by releasing and sensing autoinducer molecules, which are believed to function primarily as sensors of population density. However, this quorum-sensing hypothesis rests on very weak foundations, as neither the need for group action nor the selective conditions required for its evolution have been demonstrated. Here, I argue for a more direct function of autoi...
متن کاملEvolutionary theory of bacterial quorum sensing: when is a signal not a signal?
The term quorum sensing (QS) is used to describe the communication between bacterial cells, whereby a coordinated population response is controlled by diffusible molecules produced by individuals. QS has not only been described between cells of the same species (intraspecies), but also between species (interspecies) and between bacteria and higher organisms (inter-kingdom). The fact that QS-bas...
متن کاملQuorum sensing
although it is fair to say that the problem is still not solved. How is colour constancy achieved? It is still something of a mystery as to how your visual system achieves colour constancy, but scientists do agree that there is more than one mechanism involved. All mechanisms in some way require comparisons of the reflected light from different locations across the scene; colour constancy is a ...
متن کاملQuorum sensing network in clinical strains of A. baumannii: AidA is a new quorum quenching enzyme
Acinetobacter baumannii is an important pathogen that causes nosocomial infections generally associated with high mortality and morbidity in Intensive Care Units (ICUs). Currently, little is known about the Quorum Sensing (QS)/Quorum Quenching (QQ) systems of this pathogen. We analyzed these mechanisms in seven clinical isolates of A. baumannii. Microarray analysis of one of these clinical isol...
