Researchers find an alternative mode of bacterial quorum sensing

By the Department of Molecular Biology Whether growing in a puddle of dirty water or inside the human body, large groups of bacteria must coordinate their behavior to perform essential tasks that they would not be able to carry out individually. Bacteria achieve this coordination through a process called quorum sensing in which the microorganisms … Continue reading Researchers find an alternative mode of bacterial quorum sensing

Transition from individual to group behavior in bacteria (Journal of Bacteriology)

Bacteria use a chemical communication process called quorum sensing to control transitions between individual and group behaviors. In the bacteria known as Vibrio harveyi, two master "switches" of gene regulation, or transcription factors, coordinate the quorum-sensing response.The researchers found that one of the regulators, LuxR, acts as a sort of master switch that regulates quorum-sensing, while … Continue reading Transition from individual to group behavior in bacteria (Journal of Bacteriology)
