EFFECT OF SIDEROPHORES AGAINST E. COLI O157:H7

Italian Journal of Food Safety, 2012
In this study, the inhibiting activity of siderophores produced by Pseudomonas fluorescens against Escherichia coli O157:7 was assayed. Siderophores were extracted from P. fluorescens cultures and preliminarily tested by C.A.S. reagent and UV.

Phenotypic Adaptation of Pseudomonas aeruginosa in the Presence of Siderophore-Antibiotic Conjugates during Epithelial Cell Infection

Microorganisms, 2020
Iron acquisition pathways have often been considered to be gateways for the uptake of antibiotics into bacteria. Bacteria excrete chelators, called siderophores, to access iron.

Hydroxamate production as a high affinity iron acquisition mechanism in Paracoccidioides spp. [PDF]

PLoS ONE, 2014
Iron is a micronutrient required by almost all living organisms, including fungi. Although this metal is abundant, its bioavailability is low either in aerobic environments or within mammalian hosts.

Pseudomonas siderophores: production, spectrophotometry detection and Botrytis suppression

Notulae Scientia Biologicae
Siderophores are iron-chelating agents produced by almost all microorganisms in response to iron deficiency. Due to the requirement of iron for cell growth and metabolism, siderophore-mediated acquisition of iron plays a central role in determining the ...

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

Advanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

Mise en évidence de l’impact des sidérophores dans l’immunité des plantes et évaluation du potentiel clinique des conjugués antibiotiques-sidérophores [PDF]

, 2020
Les bactéries peuvent être à la fois nos amies et nos ennemies. Nos amies parce qu’elles nous assistent de plusieurs manières : par exemple dans la digestion de nourritures ainsi que dans le renforcement de notre système immunitaire.
