  • Title: In vitro effect of minocycline and colistin combinations on imipenem-resistant Acinetobacter baumannii clinical isolates.
    Author: Tan TY, Ng LS, Tan E, Huang G.
    Journal: J Antimicrob Chemother; 2007 Aug; 60(2):421-3. PubMed ID: 17540671.
    Abstract:
    OBJECTIVES: The study investigated the effect of colistin and minocycline when tested singly and in combination against Acinetobacter baumannii. METHODS: Thirteen unrelated imipenem-resistant A. baumannii clinical isolates were included in the study. MICs of colistin sulphate and minocycline were determined by broth macrodilution and Etest. Organisms were also tested against the two antibiotics singly and in combination using time-kill methods and an Etest-based method. RESULTS: Neither colistin nor minocycline when tested alone demonstrated bactericidal activity. However, the combination of colistin and minocycline demonstrated bactericidal activity against most of the isolates tested. At 24 h, the combination of antibiotics demonstrated synergy in 12 of the 13 isolates by time-kill methods. None of the isolates demonstrated synergy by Etest methods. CONCLUSIONS: The combination of colistin and minocycline was found to be bactericidal and synergistic against A. baumannii by time-kill methods. There was no agreement between time-kill and Etest methods for synergy testing.
