Silver resistance of sensitive Escherichia coli J53 and resistance plasmid-containing J53(pMG101) was affected by halides in the growth medium. The effects of halides on Ag+ resistance were measured with AgNO3 and silver sulfadiazine, both on agar and in liquid. Low concentrations of chloride made the differences in MICs between sensitive and resistant strains larger. High concentrations of halides increased the sensitivities of both strains to Ag+.
敏感型大肠杆菌J53及其含有耐药质粒的J53(pMG101)的银抗性受到生长培养基中卤化物的影响。通过硝酸银和磺胺嘧啶银在琼脂和液体培养基中测定卤化物对银离子抗性的影响。低浓度的氯化物使敏感菌株和耐药菌株之间的最低抑菌浓度差异更大。高浓度的卤化物增加了两种菌株对银离子的敏感性。
