Abstract excerpt

This study investigated the usefulness of the IR Biotyper, which types bacterial strains using Fourier transform infrared (FT-IR) spectroscopy, against extended-spectrum β-lactamase (ESBL)- and metallo-β-lactamase (MBL)-producing Enterobacterales. Sixty-six clinical isolates (20 ESBL-producing Klebsiella pneumoniae, 15 IMP-producing K. pneumoniae, and 31 IMP-producing Enterobacter cloacae complex isolates) were...
