title: In vitro susceptibility of anaerobic bacteria to ciprofloxacin (Bay o 9867).
abstract: About 80% of 70 clinical isolates of Bacteroides fragilis were inhibited by 4 micrograms of ciprofloxacin (Bay o 9867) per ml. The 90% MIC of ciprofloxacin was 8 micrograms/ml for other Bacteroides species, 2 micrograms/ml for Peptococcus species, 8 micrograms/ml for Peptostreptococcus species, and 16 micrograms/ml for Clostridium and Eubacterium species.
