Mean Fractional Inhibitory Index (FIC) for tobramycin and D-met concentrations. A checkerboard assay was used to determine MIC values of tobramycin (128–0.25 μg/ml) in combination with a serial dilution of D-met (6400–100 μg/ml). FIC values were calculated using previously determined MIC results for tobramycin and D-met and E. coli, S. aureus, or P. aeruginosa (n = 6 for E. coli and S. aureus; n = 5 for P. aeruginosa).
