Metagenomic Profiling and Genome-Centric Analysis Reveal Iron Acquisition Systems in Cheese-Associated Bacteria and Fungi. [PDF]

Environ Microbiol
This study describes the diversity of iron acquisition systems in cheese microorganisms and provides information on the distribution of siderophore biosynthesis pathways in both bacteria and fungi, including poorly characterised species. ABSTRACT Cheese microbial communities are composed of diverse interacting microorganisms, including both inoculated ...

Pseudomonas gessardii—A novel pathogenic bacterium associated with the cases of corneal ulcers and producing virulent pyoverdine pigment

Journal of Applied Biology & Biotechnology, 2022
Bacterial corneal ulcer (BCU) is an infection that results into loss of vision (approx. 10%) and blindness. BCU requires constant attention since antibiotic treatment failure due to genetic alteration is common in microorganisms but the present study ...

Optimised chronic infection models demonstrate that siderophore ‘cheating’ in Pseudomonas aeruginosa is context specific [PDF]

, 2017
The potential for siderophore mutants of Pseudomonas aeruginosa to attenuate virulence during infection, and the possibility of exploiting this for clinical ends, have attracted much discussion.

Copper selects for siderophore-mediated virulence in Pseudomonas aeruginosa

BMC Microbiology, 2022
Background Iron is essential for almost all bacterial pathogens and consequently it is actively withheld by their hosts. However, the production of extracellular siderophores enables iron sequestration by pathogens, increasing their virulence.

Two new siderophores produced by Pseudomonas sp. NCIMB 10586: The anti-oomycete non-ribosomal peptide synthetase-dependent mupirochelin and the NRPS-independent triabactin

Frontiers in Microbiology, 2023
IntroductionGlobisporangium ultimum is an oomycetal pathogen causing damping-off on over 300 different plant hosts. Currently, as for many phytopathogens, its control relies in the use of chemicals with negative impact on health and ecosystems. Therefore,

Iron acquisition in Pseudomonas aeruginosa by the siderophore pyoverdine: an intricate interacting network including periplasmic and membrane proteins

Scientific Reports, 2020
Pyoverdine (PVDI) has been reported to act both as a siderophore for scavenging iron (a key nutrient) and a signaling molecule for the expression of virulence factors.

Environmental modification via a quorum sensing molecule influences the social landscape of siderophore production [PDF]

, 2017
Bacteria produce a wide variety of exoproducts that favourably modify their environment and increase their fitness. These are often termed ‘public goods’ because they are costly for individuals to produce and can be exploited by non-producers (‘cheats’).

Effect of Human Burn Wound Exudate on Pseudomonas aeruginosa Virulence. [PDF]

, 2016
Burn wound sepsis is currently the main cause of morbidity and mortality after burn trauma. Infections by notorious pathogens such as Pseudomonas aeruginosa, Staphylococcus aureus, and Acinetobacter baumannii impair patient recovery and can even lead to ...

Microfluidic study of the chemotactic response of Escherichia coli to amino acids, signaling molecules and secondary metabolites [PDF]

, 2015
Quorum sensing and chemotaxis both affect bacterial behavior on the population level. Chemotaxis shapes the spatial distribution of cells, while quorum sensing realizes a cell-density dependent gene regulation.
