Pyoverdin is essential for virulence of Pseudomonas aeruginosa [PDF]

Infection and Immunity, 1996
The role of pyoverdin, the main siderophore in iron-gathering capacity produced by Pseudomonas aeruginosa, in bacterial growth in vivo is controversial, although iron is important for virulence. To determine the ability of pyoverdin to compete for iron with the human iron-binding protein transferrin, wild-type P. aeruginosa ATCC 15692 (PAO1 strain) and

Positron Emission Tomography Imaging of Bacterial Infections With an Enterobactin Analog to Monitor Treatment Efficacy With a Catechol Antibiotic

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Synopsis. The [68Ga]GaIII‐TREN‐CAM radiochelate selectively accumulates in Gram‐negative sites of infection and noninvasively monitors treatment response a siderophore antibiotic. ABSTRACT Positron emission tomography (PET) is an emerging tool under clinical investigation for the detection of bacterial infections.

Pseudomonas aeruginosa displays an epidemic population structure. [PDF]

, 2002
peer reviewedBacteria can have population structures ranging from the fully sexual to the highly clonal. Despite numerous studies, the population structure of Pseudomonas aeruginosa is still somewhat contentious. We used a polyphasic approach in order to

Biogenesis of the Pyoverdin Chromophore

Zeitschrift für Naturforschung C, 1997
Abstract After growing Pseudomonas aeruginosa in the presence of 2 ,4-[4-15N]-diaminobutyric acid (Dab) its incorporation into the quinoline chromophore of the pyoverdin produced by this bacterium could be shown by mass and NMR-spectroscopic techniques.

Iron Acquisition from Fe-Pyoverdine by Arabidopsis thaliana

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.

Deep sequencing analyses expands the Pseudomonas aeruginosa AmpR regulon to include small RNA-mediated regulation of iron acquisition, heat shock and oxidative stress response [PDF]

, 2013
Pathogenicity of Pseudomonas aeruginosa, a major cause of many acute and chronic human infections, is determined by tightly regulated expression of multiple virulence factors.

How iron limitation, combination therapy and plasmids influence antibiotic resistance evolution [PDF]

, 2022
The current antibiotic crisis highlights the importance of finding novel strategies that can be both effective and less prone to lead to the emergence of antimicrobial resistance spreading in bacterial pathogen populations.

Systematic analysis of the kalimantacin assembly line NRPS module using an adapted targeted mutagenesis approach [PDF]

, 2015
Kalimantacin is an antimicrobial compound with strong antistaphylococcal activity that is produced by a hybrid trans-acyltransferase polyketide synthase/nonribosomal peptide synthetase system in Pseudomonas fluorescens BCCM_ID9359.

Effects of exogenous pyoverdines on Fe availability and their impacts on Mn(II) oxidation by Pseudomonas putida GB-1

Frontiers in Microbiology, 2014
Pseudomonas putida GB-1 is a Mn(II)-oxidizing bacterium that produces pyoverdine-type siderophores (PVDs), which facilitate the uptake of Fe(III) but also influence MnO2 formation.
