The MICs of 12 antimicrobial agents for 42 cysteine-requiring strains of Escherichia coli showed a high concordance when determined on three different media, one of which was supplemented with cysteine. Differences in the MICs of several agents were detected between 18 prototrophic revertants and their parent auxotrophs. A total of 64.7% of the isolates were fully susceptible to all agents, and no particular resistance pattern was evident.
12种抗菌剂对42株需要半胱氨酸的大肠杆菌的最低抑菌浓度(MIC)在三种不同培养基上测定时显示出高度一致性,其中一种培养基添加了半胱氨酸。在18株原养型回复突变体及其亲本营养缺陷型之间检测到几种抗菌剂的MIC存在差异。总共64.7%的分离株对所有抗菌剂均完全敏感,未发现明显的耐药模式。
