Table 2.
MIC (μg/mL) values in low iron media of 2 in combination with sulbactam, 10, when combined 1:1 (by mass), or when 2 was tested with a constant concentration of 10 at 20 μg/mL. Individual MIC values for 2 and 10 are provided for comparison as well as the identity of each Acinetobacter isolate. See text for details.
