Quorum Sensing is a cell-to-cell communication process in which bacteria control the expression of certain genes, including virulence genes, by producing, detecting and responding to small extracellular signal molecules. Disruption of the QS mechanism of pathogens, also known as Quorum Quenching, is a potential way to control disease outbreaks in aquaculture.
Our laboratory can perform standard in vitro tests to evaluate the QS-disruptive properties of various products. These tests measure the following parameters:
Certain bacteria can produce enzymes which degrade the Quorum Sensing molecules. These bacteria can be used as QS-degrading agent to control bacterial diseases. Our laboratory offers services to isolate these QS-degrading bacteria from various samples (sediment, water, animal intestines et al.).
