Note: MIC₅₀ represents the MIC value required to inhibit the growth of 50% of the tested bacteria, and MIC₉₀ represents the MIC value required to inhibit the growth of 90% of the tested bacteria. MBC₅₀ represents the MBC value required to kill 50% of the tested bacteria, and MBC₉₀ represents the MBC value required to kill 90% of the tested bacteria. MIC, minimum inhibitory concentration; MBC, minimum bactericidal concentration; QC, quality control; ATCC, American type culture collection.
