[Bactericidal activity of ciprofloxacin and sparfloxacin. Comparison with others active antibiotics against Pasteurella multocida].
Bactericidal activities of ciprofloxacin and sparfloxacin were compared to other antibiotics active against human isolates of Pasteurella multocida. Three human isolates of Pasteurella multocida were used for killing-curve studies with ciprofloxacin and sparfloxacin comparatively to others antibiotics. At 2x the MIC, ciprofloxacin and sparfloxacin exhibited a killing of more than 99.9% of the initial viable cells that was achieved within 6 h of incubation. These activities were faster than those of amoxycillin and cefpodoxime. No regrowth was observed after 24 h of incubation. Doxycycline and clarithromycin used at MICx2 had no bactericidal activities. It was concluded that fluoroquinolones, namely ciprofloxacin and sparfloxacin, can be considered having good bactericidal activity against P. multocida.
