In-vitro susceptibility testing to determine synergistic effect of ceftazidime-avibactam with aztreonam in metallo-β-lactamase producing Enterobacterales.
OBJECTIVE The objective of study was to assess the synergistic effect of ceftazidime-avibactam (CZA) with aztreonam (ATM) against MBL-producing Enterobacterales by performing three distinct synergy testing methods and their antimicrobial susceptibility pattern. MATERIALS AND METHODS A retrospective observational stud...
