Spatial Heterogeneity of Autoinducer Regulation Systems [PDF]
Sensors, 2012 Autoinducer signals enable coordinated behaviour of bacterial populations, a phenomenon originally described as quorum sensing. Autoinducer systems are often controlled by environmental substances as nutrients or secondary metabolites (signals) from ...

Psychrophilic Quorum Sensing Genes Enable Unimodal, Adjustable Protein Expression Across the Entire Escherichia coli Population [PDF]
BioTechA previous study demonstrated that quorum sensing (QS) genes from the psychrophilic bacterium Aliivibrio logei can be used in Escherichia coli to obtain bacterial cultures with controlled amounts of a target protein. However, the QS system may be induced

A Lytic Bacteriophage Cocktail Attenuates Carbapenem-Resistant Klebsiella pneumoniae-Acinetobacter baumannii Mixed-Species Biofilms and Reshapes Transcriptional Responses. [PDF]
Microb BiotechnolA lytic phage cocktail targeting CRKP–CRAB mixed biofilms was systematically evaluated through in vitro, device‐associated, and in vivo models. Integrated transcriptomic analysis revealed molecular responses underlying biofilm disruption, providing mechanistic insights and experimental evidence supporting phage cocktails as a promising strategy against

Indole intercepts the communication between enteropathogenic E. coli and Vibrio cholerae
Gut Microbes, 2022 Reported numbers of diarrheal samples exhibiting co-infections or multiple infections, with two or more infectious agents, are rising, likely due to advances in bacterial diagnostic techniques.

Bacterial Lighthouses—Real-Time Detection of Yersinia enterocolitica by Quorum Sensing
Biosensors, 2021 Foodborne zoonotic pathogens have a severe impact on food safety. The demand for animal-based food products (meat, milk, and eggs) is increasing, and therefore faster methods are necessary to detect infected animals or contaminated food before products ...

Dynamics analysis of coupled synthetic genetic repressilators [PDF]
Компьютерные исследования и моделирование, 2010 We have investigated dynamics of synthetic genetic oscillators - repressilators - coupled through autoinducer diffusion. The model of the system with phase-repulsive coupling structure is under consideration.

Anti-Quorum-Sensing Potential of Ethanolic Extracts of Aromatic Plants from the Flora of Cyprus
Plants, 2022 Quorum sensing (QS) is a form of intra- and inter-species communication system employed by bacteria to regulate their collective behavior in a cell population-dependent manner. QS has been implicated in the virulence of several pathogenic bacteria.

Protein Model and Function Analysis in Quorum-Sensing Pathway of Vibrio qinghaiensis sp.-Q67
Biology, 2021 Bioluminescent bacteria are mainly found in marine habitats. Vibrio qinghaiensis sp.-Q67 (Q67), a nonpathogenic freshwater bacterium, has been a focus due to its wide use in the monitoring of environmental pollution and the assessment of toxicity ...
