Validation of Aztreonam-Avibactam Susceptibility Testing Using Digitally Dispensed Custom Panels

Journal of Clinical Microbiology, 2020
Aztreonam-avibactam is a combination antimicrobial agent with activity against carbapenemase-producing Enterobacteriaceae (CPE) with metallo-β-lactamases (MβLs). Although aztreonam-avibactam is not yet approved by the U.S.

Activity of aztreonam/avibactam against metallo-β-lactamase-producing Enterobacterales from the UK: Impact of penicillin-binding protein-3 inserts and CMY-42 β-lactamase in Escherichia coli [PDF]

International Journal of Antimicrobial Agents, 2023
Aztreonam/avibactam is being developed on the rationale that aztreonam evades metallo-β-lactamases (MBLs) whilst avibactam protects aztreonam against co-produced serine β-lactamases.

Hijacking a small plasmid to confer high-level resistance to aztreonam–avibactam and ceftazidime–avibactam

International Journal of Antimicrobial Agents, 2023
Acquired β-lactamase-encoding genes are typically carried by large plasmids in Gram-negative bacteria, which also commonly carry multi-copy small plasmids. This study found that mobile genetic elements carrying antimicrobial resistance genes are capable of hijacking small plasmids. This study focused on aztreonam-avibactam (ATM-AVI) as this combination
