Detection of AI-2 Receptors in Genomes of <em>Enterobacteriaceae </em>Suggests a Role of Type-2 Quorum Sensing in Closed Ecosystems

Sensors, 2012
The LuxS enzyme, an S-ribosyl-homocysteine lyase, catalyzes the production of the signal precursor for autoinducer-2 mediated quorum sensing (QS-2) in <em>Vibrio</em>.

Phosphorylation and Processing of the Quorum-Sensing Molecule Autoinducer-2 in Enteric Bacteria

, 2016
Quorum sensing is a process of chemical communication that bacteria use to assess cell population density and synchronize behavior on a community-wide scale. Communication is mediated by signal molecules called autoinducers. The LuxS autoinducer synthase

Direct Quantitation of the Quorum Sensing Signal, Autoinducer-2, in Clinically Relevant Samples by Liquid Chromatography−Tandem Mass Spectrometry

, 2016
Quorum Sensing is a type of bacterial cell-to-cell signaling that allows for cell density dependent regulation of gene expression. Many of the behaviors mediated by quorum sensing are critical for bacterial colonization or infection, and autoinducer-2 ...

The absence of luxS reduces the invasion of Avibacterium paragallinarum but is not essential for virulence

Frontiers in Veterinary Science
The contagious respiratory pathogen, Avibacterium paragallinarum, contributes to infectious coryza in poultry. However, commercial vaccines have not shown perfect protection against infectious coryza.

Phenotypic and Functional Diversity in Meat-Associated Pseudomonas Isolates: Motility, Biofilm Formation, and AI-2 Activity

Foods
Pseudomonas species are important spoilage bacteria in aerobically stored chilled meat; however, the occurrence of the interspecies quorum sensing signal autoinducer-2 (AI-2) and its association with biofilm formation and motility in these bacteria ...

Exploring the potential of Lawsonia inermis green nanoparticles to mitigate quorum sensing in multi drug resistant ESBL producing E. coli

Indian Journal of Animal Sciences
The green synthesis of nanoparticles (NPs) has shown promising results in targeting virulence, pathogenicity and quorum sensing (QS) of bacteria and are presently being considered as a promising anti-infective drug target.
