  • Title: Susceptibility of penicillin-susceptible and -resistant pneumococci to CFC-222, a new fluoroquinolone.
    Author: Kim JH, Kang JA, Lee Y, Lee KH, Lee JH, Choi EC, Kim BK.
    Journal: J Antimicrob Chemother; 1998 Oct; 42(4):527-30. PubMed ID: 9818754.
    Abstract:
    The in-vitro activity of 12 antibacterial agents against 98 clinical isolates of Streptococcus pneumoniae, including 54 penicillin-resistant strains, was determined by a standardized broth microdilution method. CFC-222, vancomycin and imipenem were the most active agents, with an MIC90 of 0.5 mg/L for the test strains. CFC-222 was 16-fold more potent than ciprofloxacin and ofloxacin against all strains tested, including both penicillin-susceptible and -resistant strains. The anti-pneumococcal activity of fluoroquinolones was not affected by penicillin susceptibility. These results indicate that CFC-222 is potentially useful for treating infection caused by penicillin-resistant strains of S. pneumoniae.
