title: In vitro activity of CI-934, a new quinolone antimicrobial, against gram-positive bacteria.
abstract: The in vitro activity of CI-934, a new quinolone antimicrobial, was compared with that of ciprofloxacin against selected gram-positive bacteria. Concentrations of CI-934 required to inhibit 90% of strains (MIC90) were twofold to eightfold lower than those of ciprofloxacin. With the exception of Streptococcus faecium, all isolates were inhibited by CI-934 at concentrations less than or equal to 1.0 microgram/ml.
