What is quorum sensing? - Ask Sawal

Quorum sensing is a process of cell–cell communication that allows bacteria to share information about cell density and adjust gene expression accordingly. In biology, quorum sensing is the ability to detect and to respond to cell population density by gene regulation. Bacteria use quorum sensing, a type of complex communication, to sense and respond to both members of their own species and ...

Quorum Sensing - an overview | ScienceDirect Topics

Quorum sensing (QS) is a bacterial cell-to-cell signaling system that controls the production of virulence factors in many pathological bacteria [96,97]. QS is mediated by the production of autoinducers, small signal molecules that activate or repress gene expression when a minimal threshold concentration is reached [96,97].
