抗生素在MIC浓度可以通过不同作用途径对大多数细菌和其它微生物产生作用,抑制它们生长或者杀灭它们。在低于MIC浓度的Sub-MIC浓度,虽然其作用并不比在MIC时弱,但发生的作用却已有所不同。Sub-MIC浓度的抗生素在不杀灭细菌,甚至不影响细菌生长的情况下使细菌形态和代谢功能多方面改变,引起形态、药物敏感性、抗原 Antibiotics at MIC concentrations can act on most bacteria and other microbes through different routes of action, inhibiting their growth or killing them. Sub-MIC concentrations below MIC concentrations, although less effective than MICs, have had different effects. Antibiotics at Sub-MIC concentrations alter bacterial morphological and metabolic functions without killing bacteria, even without affecting bacterial growth, causing morphological, drug susceptibility, antigens
