Exposure to static magnetic field stimulates quorum sensing circuit in luminescent Vibrio strains of the Harveyi clade. [PDF]

PLoS ONE, 2014
In this study, the evidence of electron-dense magnetic inclusions with polyhedral shape in the cytoplasm of Harveyi clade Vibrio strain PS1, a bioluminescent bacterium living in symbiosis with marine organisms, led us to investigate the behavior of this ...

A LuxR Homolog in a Cottonwood Tree Endophyte That Activates Gene Expression in Response to a Plant Signal or Specific Peptides

mBio, 2016
Homologs of the LuxR acyl-homoserine lactone (AHL) quorum-sensing signal receptor are prevalent in Proteobacteria isolated from roots of the Eastern cottonwood tree, Populus deltoides.

Action Mechanism of Essential Oils or Their Components Against Pathogenic Bacteria: Literature Review

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Essential oils (EOs), derived from medicinal and aromatic plants, are natural mixtures of volatile, oily compounds with varying compositions and antibacterial mechanisms. Understanding the mechanisms of EOs and their components (EOCs) is essential for predicting their impacts on various microbes and their interactions with antibiotics.

An Engineered Probiotic Consortium Based on Quorum‐Sensing for Colorectal Cancer Immunotherapy

Advanced Science, Volume 12, Issue 46, December 11, 2025.
This work develops an engineered probiotic consortium sensing pH, hypoxia, and lactate in the tumor microenvironment. It releases a lactate‐depleting enzyme (LdhA) and a PD‐L1 nanobody. In humanized mouse models (MC38 and HT‐29 tumors), it achieves durable oscillations, suppresses tumors, activates CD8+, CD4+, IFN‐γ+ T cells, and reduces Foxp3 ...

One can’t stand on its own: Are non-luminescence traits necessary for V. fischeri colonization of E. scolopes? [PDF]

, 2012
Vibrio fischeri and Euprymna scolopes squid establish mutualistic symbiosis and select for each other in the natural environment. V. fischeri provides bioluminescent camouflage for E. scolopes while E. scolopes provides nutrients for V. fischeri.

Synchronized cycles of bacterial lysis for in vivo delivery [PDF]

, 2016
The pervasive view of bacteria as strictly pathogenic has given way to an ppreciation of the widespread prevalence of beneficial microbes within the human body. Given this milieu, it is perhaps inevitable that some bacteria would evolve to preferentially

In silico analyses of conservational, functional and phylogenetic distribution of the LuxI and LuxR homologs in Gram-positive bacteria

Scientific Reports, 2017
LuxI and LuxR are key factors that drive quorum sensing (QS) in bacteria through secretion and perception of the signaling molecules e.g. N-Acyl homoserine lactones (AHLs).

Concanamycins Are Key Contributors to the Virulence of the Potato Common Scab Pathogen Streptomyces scabiei

Molecular Plant Pathology, Volume 26, Issue 11, November 2025.
Production of concanamycins by the potato common scab pathogen Streptomyces scabiei is associated with an enhanced virulence phenotype and is controlled by genetic and environmental factors. Created using BioRender. ABSTRACT The soil‐dwelling bacterium Streptomyces scabiei is distributed worldwide and is the best‐characterised causative agent of common

The Phase-Dependent Regulation of Lux-Type Genes on the Spoilage Characteristics of Hafnia alvei

Foods
Hafnia alvei, a specific spoilage microorganism, has a strong capacity to destroy food protein and lead to spoilage. The aim of this study was to evaluate the phase-dependent regulation of lux-type genes on the spoilage characteristics of H.

Global analyses of TetR family transcriptional regulators in mycobacteria indicates conservation across species and diversity in regulated functions [PDF]

, 2015
BACKGROUND: Mycobacteria inhabit diverse niches and display high metabolic versatility. They can colonise both humans and animals and are also able to survive in the environment.
