La comunicacion quorum-sensing
es uno de los mecanismos propuestos en el desarrollo y organizacion de la biopelicula, como es el caso de los sistema quorum sensing LasR/LasI y RhlR/ Rhll que facilita la formacion de biopelicula (Krishnamurthy et al.
Upon reaching a sufficient cell density on the intestinal mucosa, the Agr-like quorum-sensing
system is triggered, which in turn up-regulates the VirR/VirS regulon.
Acyl homoserinelactone quorum-sensing
All strains also contained RNAIII, which is the quorum-sensing
Inhibition of quorum-sensing
and related virulence factors of P.
The role of the QseC quorum-sensing
sensor kinase in colonization and norepinephrine-enhanced motility of Salmonella enterica serovar Typhimurium.
McLean and Clay Fuqua, "Biofilms on Indwelling Urethral Catheters Produce Quorum-Sensing
Signal Molecules In Situ and In Vitro", Applied and Environmental Microbiology, Sep 1998, 64(9): 3486-3490.
Degradation of Pathogen Quorum-Sensing
Molecules by Soil Bacteria: a Preventive and Curative Biological Control Mechanism.
Obtained results in this area revealed that the bacterial quorum-sensing
system, especially autoinducer molecules, can be considered as a novel candidate for vaccine development against P.
Phenolic components of ginger (Zingiber officinale), for example gingerol, shogaol and zingerone, have exhibited quorum-sensing
inhibitory activity (QSI) against Chromobacterium violaceum and Pseudomonas aeruginosa, (2) Chemical modification of shogaol to azashogaol and an isoxazoline derivative of gingerol were prepared, both of which exhibited good QSI activity.
qRT-PCR was used to investigate the transcription levels of curli genes (csgA and csgB), motility genes [flhD and motB), Shiga-like toxin genes (stxl and stx2), and quorum-sensing
genes (IsrA and luxS) in E.
Production of acyl-homoserine lactone quorum-sensing
signals by gram negative plant-associated bacteria.
