In vitro activity of cefiderocol and comparators against isolates of Gram-negative pathogens from a range of infection sources: SIDERO-WT-2014-2018 studies in France.

ABSTRACT:

Objectives

Over recent years, France has experienced an increase of infections caused by carbapenem-resistant Gram-negative (GN) pathogens. Cefiderocol is approved in Europe for the treatment of aerobic GN infections in adults with limited treatment options. This study evaluated the in vitro activity of cefiderocol and comparators against GN clinical isolates from France.

Methods

MICs were determined by broth microdilution, according to International Organization for Standardization guidelines. Cefiderocol was tested using iron-depleted CAMHB. Susceptibility rates were based on EUCAST breakpoints. In the absence of a species-specific breakpoint, pharmacokinetic/pharmacodynamic breakpoints were used.

Results

Of 2027 isolates, 1344 (66.3%) were Enterobacterales a
