Effect of nitroxides on swarming motility and biofilm formation, multicellular behaviors in Pseudomonas aeruginosa.
The ability of nitric oxide (NO) to induce biofilm dispersion has been well established. Here, we investigated the effect of nitroxides (sterically hindered nitric oxide analogues) on biofilm formation and swarming motility in Pseudomonas aeruginosa. A transposon mutant unable to produce nitric oxide endogenously (nirS) was deficient in swarming motility relative to the wild type and the comple...
متن کاملPhosphate starvation promotes swarming motility and cytotoxicity of Pseudomonas aeruginosa.
We investigated the transcriptional responses of Pseudomonas aeruginosa under phosphate-deficient (0.2 mM) conditions compared to phosphate sufficiency (1 mM). This elicited enormous transcriptional changes in genes related to phosphate acquisition, quorum sensing, chemotaxis, toxin secretion, and regulation. This dysregulation also led to increased virulence-associated phenotypes, including sw...
متن کاملBifA, a cyclic-Di-GMP phosphodiesterase, inversely regulates biofilm formation and swarming motility by Pseudomonas aeruginosa PA14.
The intracellular signaling molecule, cyclic-di-GMP (c-di-GMP), has been shown to influence bacterial behaviors, including motility and biofilm formation. We report the identification and characterization of PA4367, a gene involved in regulating surface-associated behaviors in Pseudomonas aeruginosa. The PA4367 gene encodes a protein with an EAL domain, associated with c-di-GMP phosphodiesteras...
متن کاملRhamnolipids modulate swarming motility patterns of Pseudomonas aeruginosa.
Pseudomonas aeruginosa is capable of twitching, swimming, and swarming motility. The latter form of translocation occurs on semisolid surfaces, requires functional flagella and biosurfactant production, and results in complex motility patterns. From the point of inoculation, bacteria migrate as defined groups, referred to as tendrils, moving in a coordinated manner capable of sensing and respon...
متن کاملImproving the reproducibility of Pseudomonas aeruginosa swarming motility assays.
Swarming motility is a rapid and coordinated migration of a bacterial population across a semi-solid surface. This multicellular phenomenon is getting increasing attention as it is suspected to be related to biofilm development of Pseudomonas aeruginosa. Published swarm plate preparation protocols differ greatly from one study to another and no reproducible and standardized protocols have been ...
