Mechanisms involved in cefiderocol resistance in French Pseudomonas aeruginosa clinical strains

Emma GAUTHIER, Matthieu PISANI, Maxime Bour, Mélanie Grosjean, Patrick Plésiat, Shahriar Safari, Ruben Christiaan Hartkoorn, Léa SOURO, Emma Prétot, Katy Jeannot

This study identifies mechanisms of cefiderocol resistance in Pseudomonas aeruginosa clinical strains, showing that acquired β-lactamases and siderophore transport defects are major contributors.
