Role of Iron Availability in Modulating Pseudomonas aeruginosa’s Antifungal Effects on Planktonic and Biofilm Growth of Scedosporium/Lomentospora Under Cystic Fibrosis-Mimicking Conditions [PDF]
Journal of FungiPseudomonas aeruginosa and Scedosporium/Lomentospora often coexist in the lungs of cystic fibrosis patients, where their interaction can affect disease outcomes. Our group has recently demonstrated that P. aeruginosa suppresses the growth of Scedosporium/

An In Vitro Cell Culture Model for Pyoverdine-Mediated Virulence
Pathogens, 2020 Pseudomonas aeruginosa is a multidrug-resistant, opportunistic pathogen that utilizes a wide-range of virulence factors to cause acute, life-threatening infections in immunocompromised patients, especially those in intensive care units.

The RND efflux system ParXY affects siderophore secretion in Pseudomonas putida KT2440
Microbiology Spectrum, 2023 Tripartite efflux systems transport antimicrobial agents, toxic metabolites, and siderophores from Gram-negative cells into the environment. For example, the main siderophore pyoverdine of the soil bacterium Pseudomonas putida KT2440 is secreted into the
