Abstract

Norfloxacin was actively pumped out by Bacteroides fragilis, which is intrinsically resistant to most fluoroquinolones. Reserpine moderately inhibited the efflux. A one-step spontaneous mutant had increased resistance to norfloxacin, ethidium bromide, and puromycin, a result suggesting that the efflux is catalyzed by a multidrug pump with specificity similar to that of NorA/Bmr.

摘要

脆弱拟杆菌可主动泵出诺氟沙星,该菌对大多数氟喹诺酮类药物具有内在抗性。利血平可适度抑制这种外排作用。一个单步自发突变体对诺氟沙星、溴化乙锭和嘌呤霉素的抗性增强,这一结果表明该外排作用是由一种与NorA/Bmr特异性相似的多药泵催化的。
