#Unit 4. Cell Communication and Cell Signaling

The regulation of gene expression in response to fluctuations in cell-population density.
A type of bacterial interaction is found to be involved in the development of antibiotic resistance by the pathogenic microorganisms.
In quorum sensing (QS), small molecules (QS factors), often called ‘auto-inducers’, serve as signals that are recognized in a population-independent manner.
Allows bacteria to monitor the environment for other bacteria and to alter behaviour on a population-wide scale in response to changes in the number and/or species present in a community
