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 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 signals and quorum-sensing genes in Burkholderia vietnamiensis.
Acyl-homoserine lactone (acyl-HSL) quorum sensing is common to many Proteobacteria including a clinical isolate of Burkholderia cepacia. The B. cepacia isolate produces low levels of octanoyl-HSL. We have examined an environmental isolate of Burkholderia vietnamiensis. This isolate produced several acyl-HSLs. The most abundant species was decanoyl-HSL. Decanoyl-HSL in B. vietnamiensis cultures ...
متن کاملQuorum sensing and quorum-quenching enzymes.
To gain maximal benefit in a competitive environment, single-celled bacteria have adopted a community genetic regulatory mechanism, known as quorum sensing (QS). Many bacteria use QS signaling systems to synchronize target gene expression and coordinate biological activities among a local population. N-acylhomoserine lactones (AHLs) are one family of the well-characterized QS signals in Gram-ne...
