An agar dilution method was used to measure the minimal inhibitory concentrations of ciprofloxacin (Bay o 9867), norfloxacin, pipemidic acid, and nalidixic acid against 496 clinical isolates. Ciprofloxacin and norfloxacin were active against all species tested (90% minimal inhibitory concentrations less than or equal to 8 micrograms/ml), although ciprofloxacin was somewhat more active, e.g., against gram-positive cocci. Pipemidic acid and nalidixic acid were active against most of the members of the Enterobacteriaceae, but Klebsiella species and Providencia stuartii were only inhibited by a high concentration of nalidixic acid.
采用琼脂稀释法测定环丙沙星(拜奥9867)、诺氟沙星、吡哌酸和萘啶酸对496株临床分离菌的最低抑菌浓度。环丙沙星和诺氟沙星对所有测试菌种均有活性(90%的最低抑菌浓度小于或等于8微克/毫升),尽管环丙沙星的活性稍强,例如对革兰氏阳性球菌。吡哌酸和萘啶酸对大多数肠杆菌科菌属有活性,但克雷伯菌属和斯氏普罗威登斯菌仅在高浓度萘啶酸作用下才被抑制。
