Quorum Quenching Revisited—From Signal Decays to Signalling Confusion

open access: yesSensors, 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

A Novel and Efficient Platform for Discovering Noncanonical Quorum-Quenching Proteins [PDF]

open access: yesMicrobiology Spectrum, 2023
Quorum sensing (QS) is a well-known chemical signaling system responsible for intercellular communication that is widespread in bacteria. Acyl-homoserine lactone (AHL) is the most-studied QS signal.

THE POTENTIAL GRAM-NEGATIVE ENDOPHYTIC BACTERIA FROM PEGAGAN (Centella asiatica) WITH QUORUM-QUENCHING ACTIVITY

open access: yesMajalah Kedokteran Andalas, 2020
Background: Quorum-sensing is communication between bacterial involved in virulence. Bacterial virulence can be inhibited by quorum-quenching mechanism. Endophytic bacteria of pegagan leaf may produce secondary metabolit similar to bioactive compounds in
