New Vocabulary for Bacterial Communication. [PDF]
Chembiochem, 2020 AbstractQuorum sensing (QS) is widely accepted as a procedure that bacteria use to converse. However, prevailing thinking places acyl homoserine lactones (AHLs) at the forefront of this communication pathway in Gram‐negative bacteria. With the advent of high‐throughput genomics and the subsequent influx of bacterial genomes, bioinformatics analysis has

Engineering nanoparticles to silence bacterial communication [PDF]
Frontiers in Microbiology, 2015 The alarming spread of bacterial resistance to traditional antibiotics has warranted the study of alternative antimicrobial agents. Quorum sensing is a chemical cell-to-cell communication mechanism utilized by bacteria to coordinate group behaviors and ...

Intercellular Nanotubes Mediate Bacterial Communication [PDF]
Cell, 2011 Bacteria are known to communicate primarily via secreted extracellular factors. Here we identify a previously uncharacterized type of bacterial communication mediated by nanotubes that bridge neighboring cells. Using Bacillus subtilis as a model organism, we visualized transfer of cytoplasmic fluorescent molecules between adjacent cells.

Gram-Negative Bacterial Envelope Homeostasis under Oxidative and Nitrosative Stress
Microorganisms, 2022 Bacteria are frequently exposed to endogenous and exogenous reactive oxygen and nitrogen species which can damage various biomolecules such as DNA, lipids, and proteins. High concentrations of these molecules can induce oxidative and nitrosative stresses

Gaseous NO2 induces various envelope alterations in Pseudomonas fluorescens MFAF76a
Scientific Reports, 2022 Anthropogenic atmospheric pollution and immune response regularly expose bacteria to toxic nitrogen oxides such as NO• and NO2. These reactive molecules can damage a wide variety of biomolecules such as DNA, proteins and lipids. Several components of the
