Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

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.

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

Optimisation de la phytoextraction : caractérisation et sélection de bactéries PGPB associées à une plante hyperaccumulatrice de Zn et Cd : Arabidopsis halleri [PDF]

, 2011
National audiencePhytotechnologies are microbial-assisted techniques that use living plants for the treatment of contaminated sites. Among these, phytoextraction based on hyperaccumulator plants such as Arabidopsis halleri, may be an option to remove ...

Le biofilm de Bacillus Subtilis : un élément central dans la gestion de son homéostasie du fer [PDF]

, 2020
Le fer est un des éléments les plus importants pour les organismes vivants. Très abondant dans le sol et pourtant peu biodisponible il est devenu une ressource stratégique pour la majorité des organismes, dont les bactéries, car il est impliqué dans de ...

Élucidation des mécanismes adaptatifs et métaboliques de Bacillus subtilis sur la plante et en présence d’espèces compétitrices [PDF]

, 2023
La conception de modèles réductionnistes pour étudier les interactions entre les plantes et les microbes ainsi qu’entre les microbes eux-mêmes ont permis d’élucider une multitude de mécanismes moléculaires, choses quasi impossibles en conditions ...

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

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.

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 ...
