Abstract:
The in vitro susceptibilities of 33 isolates of Chlamydia trachomatis, Chlamydia pneumoniae and Chlamydia psittaci to a new quinolone drug, garenoxacin (BMS-284756), in comparison with levofloxacin, ciprofloxacin, doxycycline, erythromycin and roxithromycin, were determined. Garenoxacin was the most active of the quinolone drugs tested, with identical MIC and MBC, which ranged from 0.007 to 0.03 mg/L. The MIC and MBC of the other two quinolones tested, levofloxacin and ciprofloxacin, were also identical, ranging from 0.25 to 2 mg/L. The MICs and MBCs of doxycycline, erythromycin and roxithromycin were also determined.
