Quorum sensing in group A Streptococcus
Quorum sensing (QS) is a widespread phenomenon in the microbial world that has important implications in the coordination of population-wide responses in several bacterial pathogens. In Group A Streptococcus (GAS), many questions surrounding QS systems remain to be solved pertaining to their function and their contribution to the GAS lifestyle in the host. The QS systems of GAS described to dat...
متن کاملQuorum sensing in Gram-negative bacteria: small-molecule modulation of AHL and AI-2 quorum sensing pathways.
Numerous species of bacteria employ a mechanism of intercellular communication known as quorum sensing. This signaling process allows the cells comprising a bacterial colony to coordinate their gene expression in a cell-density dependent manner.1-3 Quorum sensing is mediated by small diffusible molecules termed autoinducers that are synthesized intracellularly (throughout the growth of the bact...
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 کاملWhere antibiotic resistance mutations meet quorum-sensing
We do not need to rehearse the grim story of the global rise of antibiotic resistant microbes. But what if it were possible to control the rate with which antibiotic resistance evolves by de novo mutation? It seems that some bacteria may already do exactly that: they modify the rate at which they mutate to antibiotic resistance dependent on their biological environment. In our recent study [Kra...
