A new class of quorum quenching molecules from Staphylococcus species affects communication and growth of gram-negative bacteria. [PDF]
PLoS Pathogens, 2013 The knowledge that many pathogens rely on cell-to-cell communication mechanisms known as quorum sensing, opens a new disease control strategy: quorum quenching.

Quorum Sensing and Quorum Quenching in Agrobacterium: A “Go/No Go System”? [PDF]
Genes, 2018 The pathogen Agrobacterium induces gall formation on a wide range of dicotyledonous plants. In this bacteria, most pathogenicity determinants are borne on the tumour inducing (Ti) plasmid. The conjugative transfer of this plasmid between agrobacteria is regulated by quorum sensing (QS). However, processes involved in the disturbance of QS also occur in

Quorum Quenching Revisited—From Signal Decays to Signalling Confusion
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

Crystal Structures of a Quorum-quenching Antibody [PDF]
Journal of Molecular Biology, 2007 A large number of Gram-negative bacteria employ N-acyl homoserine lactones (AHLs) as signaling molecules in quorum sensing, which is a population density-dependent mechanism to coordinate gene expression. Antibody RS2-1G9 was elicited against a lactam mimetic of the N-acyl homoserine lactone and represents the only reported monoclonal antibody that ...

Screening of Quorum Quenching Activity of Bacteria Isolated from Ant Lion
Microbiology Indonesia, 2011 Bacterial intercellular communication or quorum sensing controls the pathogenesis of many medically important organisms. Therefore, it is important to isolate bacteria that can disintegrate the communication, in a process called quorum quenching ...

Quorum-Sensing Inhibition by Gram-Positive Bacteria
Microorganisms, 2022 The modern paradigm assumes that interspecies communication of microorganisms occurs through precise regulatory mechanisms. In particular, antagonism between bacteria or bacteria and fungi can be achieved by direct destruction of the targeted cells ...

Quorum-quenching limits quorum-sensing exploitation by signal-negative invaders [PDF]
Scientific Reports, 2017 AbstractSome bacteria produce and perceive quorum-sensing (QS) signals that coordinate several behaviours, including the costly processes that are exoenzyme production and plasmid transfer. In the case of plasmid transfer, the emergence of QS signal-altered invaders and their policing are poorly documented.
