Higher rates of cefiderocol resistance among NDM producing <i>Klebsiella</i> bloodstream isolates applying EUCAST over CLSI breakpoints

Abstract

Cefiderocol resistance rates among NDM producers are high using EUCAST criteria. Breakpoint variability may have significant implications on patient outcomes. Until more clinical outcome data are available, we suggest using EUCAST interpretive criteria for cefiderocol susceptibility testing.
