Bacterial quorum sensing, cooperativity, and anticipation ... Interfering with Bacterial Quorum Sensing

Hence, disruption of bacterial quorum sensing has been proposed as a new anti-infective strategy and several techniques that could be used to disrupt quorum sensing have been investigated. These techniques comprise (1) the inhibition of signal molecule biosynthesis, (2) the application of quorum sensing antagonists (including natural

Quorum sensing (QS) is a type of bacterial cell–cell communication system used to coordinate the expression of genes in response to small signal molecules, known as autoinducers (Fig. 8.6).Several types of QS systems have been described, with different degrees of specificity.

Introduction. Quorum sensing is a term used to describe bacterial cell‐to‐cell signaling involved in the determination of bacterial physiology (for review, see Fuqua and Greenberg 2002).This signaling is mediated by small diffusible molecules called autoinducers, usually oligopeptides and N‐acyl homoserine lactones in Gram‐positive and Gram‐negative bacteria, respectively.
