Fig. 6 A combination of bacitracin together with ciprofloxacin or levofloxacin increases the potency of these fluoroquinolones.

A Ciprofloxacin (5 mg/ml) disc diffusion assays show an increased zone-of-inhibition of strain D39V with the addition of 0.5 μg/ml bacitracin (BAC). Checkerboard assays with levofloxacin (LEV) and BAC indicate a synergistic interaction (FICI = 0.5) for (B) D39V and the fluoroquinolone-resistant strains (C) FQR_25191 and D FQR_40109 (see Methods).
