Autoinducer-2 Quorum Sensing Influences Viability of Escherichia coli O157:H7 under Osmotic and In Vitro Gastrointestinal Stress Conditions

Frontiers in Microbiology, 2017
Bacteria use autoinducer molecules to communicate both at intra-species and inter-species levels by quorum sensing. One such cell density-dependent signaling system is the luxS-mediated universal quorum sensing using autoinducer-2 (AI-2).

An Experimentally Verified Mechanistic Model for Predicting Quorum Sensing‐Based Switches

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
A predictive model was developed to fine‐tune EsaI/EsaR quorum sensing circuits, highlighting the transcription factor's pivotal role and offering a foundation for broader applications across LuxR‐family systems in synthetic biology. ABSTRACT Quorum sensing‐based genetic circuits are gaining traction in synthetic biology as they link population‐level ...

Fungal‐Bacterial Interactions in Polymicrobial Infections: Hidden Threats

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
ABSTRACT Polymicrobial infections involving fungi and bacteria represent a major and increasingly recognized clinical challenge, in which interkingdom interactions significantly amplify disease severity, antimicrobial resistance, and treatment failure. Rather than passive co‐existence, fungal–bacterial communities form highly coordinated systems driven

Essential Oils and Their Multifunctional Activities Against Pseudomonas aeruginosa: Current Evidence and Perspectives

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Essential oils show multifunctional activity against multidrug‐resistant Pseudomonas aeruginosa by targeting bacterial membranes, quorum sensing, biofilm formation, virulence traits, and antibiotic susceptibility. Their translational potential depends on standardized composition, optimized delivery systems, safety assessment, and clinical validation ...

Autoinducer 2 bei C. jejuni [PDF]

, 2016
The ability of Campylobacter (C.) jejuni, the leading cause of food borne bacterial enteritis worldwide, to produce the Quorum sensing molecule autoinducer-2 (AI-2) provides new insights into the mechanisms by which C. jejuni regulates its behavior.

Pathogenic Mechanisms of V. vulnificus and Its Role in the Development of Sepsis

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Sorafenib attenuates urethral scar formation by inhibiting β‐catenin signaling in fibroblasts, which downregulates the SLC7A11/GPX4 antioxidant axis and triggers ferroptosis. This β‐catenin–ferroptosis coupling effectively suppresses fibrogenesis, highlighting sorafenib as a promising drug‐repurposing candidate for urethral stricture.

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

, 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

Where antibiotic resistance mutations meet quorum-sensing

Microbial Cell, 2014
We do not need to rehearse the grim story of the global rise of antibiotic resistant microbes. But what if it were possible to control the rate with which antibiotic resistance evolves by de novo mutation?
