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.

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 ...

Periodically Disturbing the Spatial Structure of Biofilms Can Affect the Production of an Essential Virulence Factor in Pseudomonas aeruginosa

mSystems, 2021
Understanding the environmental factors that affect the production of virulence factors has major implications in evolution and medicine. While spatial structure is important in virulence factor production, observations of this relationship have occurred

The biosynthesis of pyoverdines [PDF]

Microbial Cell, 2018
Pyoverdines are fluorescent siderophores of pseudomonads that play important roles for growth under iron-limiting conditions. The production of pyoverdines by fluorescent pseudomonads permits their colonization of hosts ranging from humans to plants.

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 ...

Pyoverdine aus Pseudomonas putida / Pyoverdins from Pseudomonas putida

Zeitschrift für Naturforschung C, 1992
The structures of two pyoverdins (Pp 1 and Pp 2) and one dihydropyoverdin (dihydro-Pp 2) from a strain of Pseudomonas putida have been elucidated by spectroscopic methods and degradation studies. The pyoverdins Pp 1 and Pp2 consist of a chromophore which was identified as (1 S)-5-amino-2,3-dihydro-8,9-dihydroxy-1 H-pyrimido[1,2-a]quinoline-1-carboxylic

PvdL Orchestrates the Assembly of the Nonribosomal Peptide Synthetases Involved in Pyoverdine Biosynthesis in Pseudomonas aeruginosa

bioRxiv, 2023
The pyoverdine siderophore is produced by Pseudomonas aeruginosa to access iron. Its synthesis involves the complex co-ordination of four nonribosomal peptide synthetases (NRPSs), responsible for assembling the pyoverdine peptide backbone.

Presence of a loner strain maintains cooperation and diversity in well-mixed bacterial communities [PDF]

, 2016
Cooperation and diversity abound in nature despite cooperators risking exploitation from defectors and superior competitors displacing weaker ones. Understanding the persistence of cooperation and diversity is therefore a major problem for evolutionary ...
