Anti-anaerobic activity of levofloxacin alone and combined with clindamycin and metronidazole.

摘要

Microdilution MICs of levofloxacin against twelve anaerobes ranged between 0.5-8.0 microg/ml and those of clindamycin and metronidazole between 0.008-2.0 and 0.25->16.0 microg/ml, respectively. Combination of levofloxacin with clindamycin and/or metronidazole in time-kill tests led to synergy at levofloxacin concentrations at or below the MIC in 7/12 strains.
