CerM and Its Antagonist CerN Are New Components of the Quorum Sensing System in Cereibacter sphaeroides, Signaling to the CckA/ChpT/CtrA System. [PDF]
The quorum sensing (QS) system of Cereibacter sphaeroides includes six LuxR homologs and one acylhomoserine lactone synthase homolog. Two LuxR homologs, CerM and CerN, are involved in regulating the expression of ctrA, which is part of the CckA/ChpT/CtrA two‐component system that controls flagellar motility.

Implications of Rewiring Bacterial Quorum Sensing [PDF]
Bacteria employ quorum sensing, a form of cell-cell communication, to sense changes in population density and regulate gene expression accordingly.

The pathogen Pseudomonas aeruginosa uses quorum sensing (QS) to control virulence and biofilm formation. Enzymatic disruption of quorum sensing is a promising anti-infection therapeutic strategy that does not rely on antibiotics.

Determination of N-acylhomoserine lactones of Pseudomonas aeruginosa in clinical samples from dogs with otitis externa [PDF]
Bacterial intercellular communication, called quorum sensing, takes place via the production and collective response to signal molecules. In Gram-negative bacteria, like Pseudomonas aeruginosa, these signaling molecules are N-acylhomoserine lactones (AHLs). P. aeruginosa is a common cause of inflammation of the ear canal (otitis externa) in dogs.

Quorum Sensing: suatu Sistem Komunikasi Bakteri Fitopatogen, Peranannya pada Proses Infeksi, dan Peluangnya sebagai Basis Pengembangan Strategi Baru dalam Pengendalian Penyakit Tumbuhan [PDF]
Previously, it is thought that bacterium is an autonomous unicellular organism with no capacity for collective behavior. Now the paradigm has changed since there are communication between intercell bacteria.

The fitness burden imposed by synthesising quorum sensing signals [PDF]
It is now well established that bacterial populations utilize cell-to-cell signaling (quorum-sensing, QS) to control the production of public goods and other co-operative behaviours.

Non-antibiotic quorum sensing inhibitors acting against N-acyl homoserine lactone synthase as druggable target [PDF]
YesN-acylhomoserine lactone (AHL)-based quorum sensing (QS) is important for the regulation of proteobacterial virulence determinants. Thus, the inhibition of AHL synthases offers non-antibiotics-based therapeutic potentials against QS-mediated bacterial

Effect of sdiA on Biosensors of N -Acylhomoserine Lactones [PDF]
ABSTRACT Many gram-negative bacteria synthesize N -acylhomoserine lactones (AHLs) and then use transcription factors of the LuxR family to sense and respond to AHL accumulation in the environment; this phenomenon is termed quorum sensing.
