Checkerboard assays of PapMA-3 in combination with six conventional antibiotics against CRAB C1. PapMA-3 and antibiotics were subjected to 1/2 dilution vertically and horizontally from the MIC concentration at the upper left corner. White (0.5 < FICI < 2) indicates a partial synergistic effect, yellow (FICI = 0.5) and orange (FICI < 0.5) indicate a synergistic effect, and gray indicates growth of bacteria. We defined MIC that inhibits completely over 99% of CRAB C1 bacterial growth.
