Within-host succession from an OXA-48-like to an NDM-type carbapenemase in clonal ST361 Escherichia coli recovered from sequential urinary and bloodstream infection

Leon Kassabian, Charbel Al Khoury, George Farah Araj, Sima T. Tokajian

The paper describes the within-host succession of carbapenemase types in E. coli isolates from a single patient, showing a shift from OXA-48-like to NDM-type resistance due to plasmid displacement.
