Quorum-quenching microbial infections: mechanisms and implications.
The discovery of antibiotics early in the past century marked the beginning of active control and prevention of infectious microbial diseases. However, extensive use of antibiotics has also unavoidably resulted in the emergence of ‘superbugs’ that resist conventional antibiotics. The finding that many pathogens rely on cell-to-cell communication mechanisms, known as quorum sensing, to synchroni...
متن کاملResistance to quorum-quenching compounds.
Bacteria have the remarkable ability to communicate as a group in what has become known as quorum sensing (QS), and this trait has been associated with important bacterial phenotypes, such as virulence and biofilm formation. Bacteria also have an incredible ability to evolve resistance to all known antimicrobials. Hence, although inhibition of QS has been hailed as a means to reduce virulence i...
متن کاملQuorum 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 quenching for the management of dental plaque microbes
In the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (TC) as compared to those from normal persons (non tobacco chewers) (NTC). Bacterial strain J1 (dominant in the plaques of NTC) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...
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...
