Time kill curve demonstrating in vitro efficacy of doxycycline in colistin resistant clinical isolate AB-4 (A) Kill curve of AB-4 upon the treatment with different concentrations of doxycycline. The MIC value for doxycycline in AB-4 is 0.5 ug/ml (B) Kill curve of A. baumannii 17978 (AB17978 upon the treatment with different concentrations of doxycycline. The MIC value for doxycycline in AB17978 is 0.125 ug/ml (C) Kill curve of AB-4 upon the treatment with different concentrations of colistin. The MIC value for colistin in AB-4 is 16 ug/ml (D) Kill curve of AB-4 upon the treatment with colistin and doxycycline. Bars show mean ± standard deviation from at least five independent biological experiments.
