Functional Plasticity of Microbial Siderophores in Iron- and Boron-Rich Niches

Applied Microbiology
Siderophores are high-affinity iron-chelating metabolites that underpin microbial survival in iron-limited environments and play central roles in metal homeostasis, ecological competition, and pathogenesis.

Catecholate siderophores protect bacteria from pyochelin toxicity. [PDF]

PLoS ONE, 2012
Bacteria produce small molecule iron chelators, known as siderophores, to facilitate the acquisition of iron from the environment. The synthesis of more than one siderophore and the production of multiple siderophore uptake systems by a single bacterial ...

Simultaneous modification of Thermotoga maritima encapsulin subunits to produce multivalent nanoparticle vaccines for non‐typhoidal Salmonella enterica

The FEBS Journal, EarlyView.
This study investigates the modularity of encapsulin—a protein nanoparticle—by simultaneously inserting up to four distinct Salmonella epitopes within the encapsulin subunit. The encapsulin variants were transiently expressed in plants where they assembled into nanoparticles; however, their accumulation and stability varied depending on the ...

Siderophore-Based Molecular Imaging of Fungal and Bacterial Infections—Current Status and Future Perspectives

Journal of Fungi, 2020
Invasive fungal infections such as aspergillosis are life-threatening diseases mainly affecting immuno-compromised patients. The diagnosis of fungal infections is difficult, lacking specificity and sensitivity.

Efficacy Assessment of Montanide GEL 02 PR and Liposome‐Based Encapsulation as Adjuvants for an FrpA Subunit Vaccine Against Photobacteriosis in Solea senegalensis

Journal of Fish Diseases, EarlyView.
ABSTRACT Photobacteriosis is a major threat to marine aquaculture, and the siderophore transporter FrpA represents a promising target for effective subunit vaccine development. In this study, we evaluated Montanide GEL 02 PR and phosphatidylcholine‐based liposomes as aqueous and safer alternatives to Freund's adjuvant for an FrpA‐based subunit vaccine ...

Distribution and Cycling of Siderophores in the Eastern North and Tropical Pacific Oceans

Geophysical Research Letters
Most iron (Fe) dissolved in seawater is complexed to organic ligands of unknown composition. Here we investigate the distribution of siderophores, small organic compounds synthesized by microbes to bind environmental Fe and facilitate its transport into ...

Siderophore production in Botryosphaeriaceae fungi associated with grapevine trunk diseases

The Microbe
Fungi from the Botryosphaeriaceae are recognized as causal agents of dieback diseases in a variety of economically important woody plants, including grapevine. Some species produce secondary metabolites that may function as virulent factors.

Variation in siderophore biosynthetic gene distribution and production across environmental and faecal populations of Escherichia coli. [PDF]

PLoS ONE, 2015
Iron is essential for Escherichia coli growth and survival in the host and the external environment, but its availability is generally low due to the poor solubility of its ferric form in aqueous environments and the presence of iron-withholding proteins

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

Temperature, Disinfectant Concentration and Bacterial Innate Properties Influence the Disinfection of Bacterial Pathogens Relevant to Catfish Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Aquaculture systems suffer a wide range of losses, mostly due to bacterial disease outbreaks, and the use of disinfectants is a routine practice for controlling the spread of pathogenic organisms globally. Including Aeromonas hydrophila, Streptococcus agalactiae and Edwardsiella tarda, implicated for natural disease outbreaks and economic ...
