Insights on the virulence mechanisms of European Edwardsiella tarda strains isolated from turbot

Frontiers in Marine Science, 2014
Edwardsiella tarda is a common inhabitant of diverse ecological niches as well as a common guest of a high variety of animals including fish, reptiles, amphibians, chickens and other warm-blooded animals as humans. With regard to the aquatic environments,

Phenotypic and genotypic characterisation of Burkholderia cenocepacia J2315 mutants affected in homoserine lactone and diffusible signal factor-based quorum sensing systems suggests interplay between both types of systems [PDF]

, 2013
Many putative virulence factors of Burkholderia cenocepacia are controlled by various quorum sensing (QS) circuits. These QS systems either use N-acyl homoserine lactones (AHL) or cis-2-dodecenoic acid ("Burkholderia diffusible signal factor'', BDSF) as ...

Pre-sowing treatment of acorns with gibberellic acid and N-hexanoyl-L-homoserine lactone induced changes in growth and hormonal balance of Quercus robur L. seedlings

Metsanduslikud Uurimused
This study aimed to assess and compare the impact of priming with gibberellic acid (GA3) and N-hexanoyl-L-homoserine lactone (C6-HSL) on acorn germination, seedling growth, and the balance of endogenous phytohormones in 47-day-old seedlings of ...

Presence of acyl-homoserine lactones in 57 members of the Vibrionaceae family [PDF]

, 2013
Aims: The aim of this study was to use a sensitive method to screen and quantify 57 Vibrionaceae strains for the production of acyl-homoserine lactones (AHLs) and map the resulting AHL profiles onto a host phylogeny.

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.

Breaking the biofilm barrier: Juglone derivatives as dual-action inhibitors and anti-quorum sensing agents

Phytomedicine Plus
Background: Most nosocomial infections are caused by bacteria that proliferate within quorum sensing mediated biofilms. The disruption of quorum sensing signals in biofilm-forming bacteria is the potential substitution strategy.

Marine-derived quorum-sensing inhibitory activities enhance the antibacterial efficacy of tobramycin against Pseudomonas aeruginosa. [PDF]

, 2014
Bacterial epiphytes isolated from marine eukaryotes were screened for the production of quorum sensing inhibitory compounds (QSIs). Marine isolate KS8, identified as a Pseudoalteromonas sp., was found to display strong quorum sensing inhibitory (QSI ...
