    AbstractThis study assessed the in vitro synergy between ceftazidime, aztreonam, and ceftazidime-avibactam against serine and metallo-β-lactamase (MBL)-producing pathogens via the Etest MIC:MIC ratio and Agar-Etest synergy methods. The combination of aztreonam and ceftazidime-avibactam was synergistic against all Enterobacteriaceae. None of the tested combinations were consistently synergistic against IMP-producing P. aeruginosa.Copyright © 2017 Elsevier Inc. All rights reserved.
