Minimal inhibitory concentrations (MICs) of ticarcillin/clavulanic acid (TLc), ceftolozane/tazobactam (C/T), and aztreonam (AT) were determined for 6 SPM-1-producing Pseudomonas aeruginosa (PSA) using Etest® strips and the synergistic effect of such antimicrobials against was evaluated by gradient diffusion strip crossing (GDSC) test. The fraction inhibitory concentration indexes (FICI) were calculated and showed a synergistic (n = 3) and additive (n = 2) effects of TLc + AT against SPM-1 producers, while TLc + C/T combination caused
