  1. a Minimal inhibitory concentrations (MIC) was determined at the endpoint of MIC-0, which is defined as the lowest agent concentration showing no more than 10% growth in comparison to that of the growth control. The data represents the median obtained from three independent experiments.
  2. b FIC is a fraction inhibitory concentration that was calculated by dividing the MIC value of agent in combination by the MIC value of the agent alone.
  3. c FICi is a FIC index, indicating the sum of the FICs of the two agents in the pairs.
  4. d Interactions: SYN, synergism (FICi <0.5); ADD, additivity (FICi 0.5–1.0); IND, indifference (FICi 1.0 – 4.0); ANT, antagonism (FICi >4).
