Background In Gram-negative bacteria, the most commonly studied quorum sensing signals are the N-acylhomoserine lactones (AHLs). In Salmonella, AHLs are recognized by SdiA, which is believed to be a sensor of AHLs produced by other bacteria, since ...

Global and Phylogenetic Distribution of Quorum Sensing Signals, Acyl Homoserine Lactones, in the Family of Vibrionaceae [PDF]
Bacterial quorum sensing (QS) and the corresponding signals, acyl homoserine lactones (AHLs), were first described for a luminescent Vibrio species. Since then, detailed knowledge has been gained on the functional level of QS; however, the abundance of ...

Inhibition of Quorum Sensing-Mediated Biofilm Formation and Spoilage Factors in Pseudomonas fluorescens by Plasma-Activated Water [PDF]
Plasma-activated water (PAW) is an emerging disinfectant; however, its potential as a quorum sensing inhibitor (QSI) for biofilm control remains underexplored, and its action mechanisms have not been elucidated. This study investigated the effects of PAW

Regulatory Mechanisms of Exogenous Acyl-Homoserine Lactones in the Aerobic Ammonia Oxidation Process Under Stress Conditions [PDF]
This study investigated the mechanism by which N-acyl-homoserine lactone (AHL) signaling molecules influence ammonia-oxidizing microorganisms (AOMs) under inhibitory conditions.

N-acyl homoserine lactone signaling modulates bacterial community associated with human dental plaque [PDF]
Dental plaque is a complex oral biofilm responsible for periodontal diseases. Bacterial biofilms are often regulated by Quorum Sensing (QS) mediated by N-acyl homoserine lactones (AHLs). While their presence and roles in oral microbiota have been debated,

Effect of shear stress on Pseudomonas aeruginosa isolated from the cystic fibrosis lung [PDF]
Chronic colonization of the lungs by Pseudomonas aeruginosa is one of the major causes of morbidity and mortality in cystic fibrosis (CF) patients. To gain insights into the characteristic biofilm phenotype of P. aeruginosa in the CF lungs, mimicking the

Acyl homoserine lactones from culture supernatants of Pseudomonas aeruginosa accelerate host immunomodulation. [PDF]
The virulence of Pseudomonas aeruginosa is multifactorial and under the control of quorum sensing signals, such as acyl homoserine lactones (AHLs). The importance of these molecules in the establishment of infection has been previously reported.
