Candida albicans Inhibits Pseudomonas aeruginosa Virulence through Suppression of Pyochelin and Pyoverdine Biosynthesis. [PDF]

PLoS Pathogens, 2015
Bacterial-fungal interactions have important physiologic and medical ramifications, but the mechanisms of these interactions are poorly understood.

Opening Study on the Development of a New Biosensor for Metal Toxicity Based on Pseudomonas fluorescens Pyoverdine [PDF]

Biosensors, 2013
To date, different kinds of biosensing elements have been used effectively for environmental monitoring. Microbial cells seem to be well-suited for this task: they are cheap, adaptable to variable field conditions and give a measurable response to a ...

Inhibition of Xanthomonas fragariae, Causative Agent of Angular Leaf Spot of Strawberry, through Iron Deprivation [PDF]

Frontiers in Microbiology, 2016
In commercial production settings, few options exist to prevent or treat angular leaf spot of strawberry, a disease of economic importance and caused by the bacterial pathogen Xanthomonas fragariae (Xfr).

Iron Acquisition from Fe-Pyoverdine by Arabidopsis thaliana [PDF]

Molecular Plant-Microbe Interactions, 2007
Taking into account the strong iron competition in the rhizosphere and the high affinity of pyoverdines for Fe(III), these molecules are expected to interfere with the iron nutrition of plants, as they do with rhizospheric microbes.

Novel Pyoverdine Inhibitors Mitigate Pseudomonas aeruginosa Pathogenesis [PDF]

Frontiers in Microbiology, 2019
Pseudomonas aeruginosa is a clinically important pathogen that causes a variety of infections, including urinary, respiratory, and other soft-tissue infections, particularly in hospitalized patients with immune defects, cystic fibrosis, or significant ...

<i>Pseudomonas aeruginosa</i> Biofilms in Cystic Fibrosis: Interactions, Methods, and Therapeutic Strategies. [PDF]

Biomed Res Int
This review explores the role of Pseudomonas aeruginosa biofilms in cystic fibrosis (CF) pathogenesis. Biofilms, the main bacterial lifestyle in CF lungs, are key in therapy failure, immune evasion, and chronic infection persistence. This review examines biofilm structure, emphasizing extracellular polymeric substances (Psl, Pel, alginate, eDNA) and ...

Patient-Specific Coculture of S. aureus and P. aeruginosa Enhances Epithelial Barrier Disruption and Virulence in CRS. [PDF]

Int Forum Allergy Rhinol
ABSTRACT Background Chronic rhinosinusitis (CRS) is a chronic inflammatory disease that is associated with polymicrobial infections, often involving S. aureus and P. aeruginosa. It is unclear whether the polymicrobial context plays a role in exacerbating epithelial damage, inflammation, and resistance to therapy. Methods S. aureus and P. aeruginosa (n =

The Burden of Antimicrobial-Resistant Pseudomonas aeruginosa Isolates in Children With Cystic Fibrosis: Molecular Characterization and Genotyping Analysis. [PDF]

Microbiologyopen
This study highlights the prevalence of multidrug‐ and carbapenem‐resistant Pseudomonas aeruginosa in pediatric cystic fibrosis patients, along with the presence of carbapenemase‐encoding genes and genetic profiles, suggesting clonal spread. These findings underscore the urgent need for surveillance and strategies to combat resistant strains and ...

Indole-Acetic Acid Impairs Pseudomonas aeruginosa Virulence and Alters Lung Infection in Mice. [PDF]

Microbiologyopen
Screening for anti‐virulence activity exerted by tryptophan catabolites on laboratory and clinical strains of Pseudomonas aeruginosa showed that Indoleacetic acid (IAA) inhibits motility and pigment production, downregulates PQS gene expression, while increases oxidative stress sensitivity.

Comparative genomics of isolates of a pseudomonas aeruginosa epidemic strain associated with chronic lung infections of cystic fibrosis patients [PDF]

, 2014
Pseudomonas aeruginosa is the main cause of fatal chronic lung infections among individuals suffering from cystic fibrosis (CF). During the past 15 years, particularly aggressive strains transmitted among CF patients have been identified, initially in ...
