Quorum sensing allows individual bacteria within colonies to coordinate and carry out colony-wide functions such as: sporulation, bioluminescence, virulence, conjugation, competence and biofilm formation. How does quorum sensing work? during their reproductive cycle, individual bacterium synthesize autoinducers.
Quorum sensing is defined as a mechanism by which bacteria regulate specific target genes in response to a critical concentration of signal molecules, which is a measurement of the cell density of a bacterial population.
Autoinducer 2 (ai-2) is a quorum sensing molecule to which bacteria respond to regulate various phenotypes, including virulence and biofilm formation. Ai-2 plays an important role in the formation of a subgingival biofilm composed mostly of gram-negative anaerobes, by which periodontitis is initiated. The aim of this study was to evaluate d-galactose as an inhibitor of ai-2 activity and thus.

Quorum sensing (qs) facilitates biofilm formation and therefore the search for 'quorum quenchers' has increased recently. Such compounds are expected to inhibit biofilm formation and hence reduce/prevent development of drug resistance in the bacteria. Some of these compounds also target synthesis of some virulence factors (vf).
In biology, quorum sensing (or quorum signalling) is the ability to detect and respond to cell population density by gene regulation. As one example, quorum sensing (qs) enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial.
Size-dependent gene regulation is quorum sensing (qs), involving communication between bacteria. In spite of the ancient origins of the word “quorum”, qs is a relatively new area of science. When leuweenhoek first glimpsed inside the bacterial world, it was thought that microbes.
