In Vitro Activity of Aztreonam-Avibactam against Enterobacteriaceae and Pseudomonas aeruginosa Isolated by Clinical Laboratories in 40 Countries from 2012 to 2015.

ABSTRACT: The combination of the monobactam aztreonam and the non-β-lactam β-lactamase inhibitor avibactam is currently in clinical development for the treatment of serious infections caused by metallo-β-lactamase (MBL)-producing Enterobacteriaceae, a difficult-to-treat subtype of carbapenem-resistant Enterobacteriaceae for which therapeutic options are currently very limited. The present study tested clinically significant isolates of Enterobacteriaceae (n = 51,352) and Pseudomonas aeruginosa (n = 11,842) collected from hospitalized patients in 208 medical center laboratories from 40 countries from 2012 to 2015 for in vitro susceptibility to aztreonam-avibactam, aztreonam, and comparator antimicrobial agents using a standard broth microdilution methodology. Avibactam was tested at a fixed concentra
