Comparative Evaluation of Commercial Gradient Diffusion and Disk Diffusion Tests for Aztreonam-Avibactam Susceptibility Testing

2026-07-26

Abstract excerpt

<h4>Background</h4> Aztreonam–avibactam (AZA) is a recently approved agent active against metallo-β-lactamase-producing Enterobacterales. However, independent evaluations of commercially available antimicrobial susceptibility testing (AST) products remain limited. <h4>Methods</h4> We evaluated 56 carbapenem-resistant Enterobacterales isolates using four newly available AZA AST products, including two gradient di...
