Phloretin, an Apple Phytoalexin, Affects the Virulence and Fitness of Pectobacterium brasiliense by Interfering With Quorum-Sensing

Frontiers in Plant Science, 2021
The effects of phloretin a phytoalexin from apple, was tested on Pectobacterium brasiliense (Pb1692), an emerging soft-rot pathogen of potato. Exposure of Pb1692 to 0.2 mM phloretin a concentration that does not affect growth, or to 0.4 mM a 50% growth ...

Discovery of new diketopiperazines inhibiting Burkholderia cenocepacia quorum sensing in vitro and in vivo [PDF]

, 2016
Burkholderia cenocepacia, an opportunistic respiratory pathogen particularly relevant for cystic fibrosis patients, is difficult to eradicate due to its high level of resistance to most clinically relevant antimicrobials.

Infant‐Type Bifidobacteria as Biocontrol Agents: Suppressing Listeria monocytogenes via Key Virulence Gene Alteration

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Infant‐type bifidobacteria exhibit potential as targeted biocontrol agents against Listeria monocytogenes infections. However, the strain‐specific antimicrobial efficacy and molecular mechanisms remain insufficiently characterized. In this study, the probiotic potential of five bifidobacteria strains was systematically evaluated through comprehensive ...

CerM and Its Antagonist CerN Are New Components of the Quorum Sensing System in Cereibacter sphaeroides, Signaling to the CckA/ChpT/CtrA System

MicrobiologyOpen, Volume 13, Issue 6, December 2024.
The quorum sensing (QS) system of Cereibacter sphaeroides includes six LuxR homologs and one acylhomoserine lactone synthase homolog. Two LuxR homologs, CerM and CerN, are involved in regulating the expression of ctrA, which is part of the CckA/ChpT/CtrA two‐component system that controls flagellar motility.

Characterisation of two quorum sensing systems in the endophytic Serratia plymuthica strain G3: differential control of motility and biofilm formation according to life-style

BMC Microbiology, 2011
Background N-acylhomoserine lactone (AHL)-based quorum sensing (QS) systems have been described in many plant-associated Gram-negative bacteria to control certain beneficial phenotypic traits, such as production of biocontrol factors and plant growth ...

Dialogues of root-colonizing biocontrol pseudomonads [PDF]

, 2018
Among biocontrol agents that are able to suppress root diseases caused by fungal pathogens, root-colonizing fluorescent pseudomonads have received particular attention because many strains of these bacteria trigger systemic resistance in host plants and ...

Exploring Naturally Tailored Bacterial Outer Membrane Vesicles for Selective Bacteriostatic Implant Coatings

Advanced Science, Volume 11, Issue 39, October 23, 2024.
Bacterial outer membrane vesicles (OMVs) are now used to construct implant coatings, showing unexpected selective bacteriostasis at the macroscopic level. Using a simple polyphenol bridging technology stabilizes bacterial OMVs on various implant surfaces. This OMVs coating gives implants the ability to selectively inhibit bacteria. This method provides

Purification and characterisation of a quorum quenching AHL-lactonase from the endophytic bacterium Enterobacter sp. CS66. [PDF]

, 2018
The quorum quenching (QQ) activity of endophytic bacteria associated with medicinal plants was explored. Extracts of the Gram-negative Enterobacter sp. CS66 possessed potent N-acylhomoserine lactone (AHL) hydrolytic activity in vitro.
