title: Amifloxacin activity against well-defined gentamicin-resistant, gram-negative bacteria.
abstract: Amifloxacin (WIN 49375) activity against a well-defined group of gentamicin-resistant gram-negative bacilli was compared with the activity of 11 other antimicrobial agents. For all strains, amifloxacin and norfloxacin were the most active agents, followed by cefotaxime and moxalactam. For Acinetobacter sp. only amifloxacin had an achievable MIC for 90% of the strains. Amifloxacin joins other newly developed DNA gyrase inhibitors as potentially useful agents for infections due to aminoglycoside-resistant gram-negative bacilli.
