Quorum Quenching Revisited—From Signal Decays to Signalling Confusion [PDF]
Sensors, 2012 In a polymicrobial community, while some bacteria are communicating with neighboring cells (quorum sensing), others are interrupting the communication (quorum quenching), thus creating a constant arms race between intercellular communication. In the past
