Evaluation of two gradient diffusion tests to determine susceptibility to aztreonam and ceftazidime–avibactam in combination

7 Feb 2025

Abstract excerpt

ABSTRACT The combination of aztreonam and ceftazidime–avibactam (ATM–CZA) is a last resort regimen against recalcitrant infections caused by metallo-β-lactamase (MBL)-producing organisms. Susceptibility testing is warranted due to emerging resistance to the combination, but there are no widely implemented methods for use in clinical laboratories. Here, we used a cohort of 100 Enterobacterales , Pseudomonas...
