MIC, minimal inhibitory concentration.
*MIC values were shown in the table for Trimethoprim, corresponding to the MIC of Trimethoprim/sulfamethoxazole 0.5/9.5, 1/19, 2/38, 4/76 (mg/L). The bold values are the frequencies for the values of MIC90, the concentration at which 90% of bacterial strains are inhibited.
