Time-kill curves of A. baumannii isolates using the drugs alone or in combination. The capsaicin concentrations of ATCC19606-R, Ab13-R and Ab156-R were 32 μg/mL, 256 μg/mL, 32 μg/mL, respectively; at which the MIC values of colistin are below the susceptibility breakpoint (2 μg/mL). (A): Time-kill curves of ATCC19606-R using capsaicin (32 μg/mL) or colistin (2 μg/mL) without or with capsaicin (32 μg/mL). (B): Time-kill curves of Ab13-R using capsaicin (256 μg/mL) or colistin (2 μg/mL) without or with capsaicin (256 μg/mL). (C): Time-kill curves of Ab156-R using capsaicin (32 μg/mL) or colistin (2 μg/mL) without or with capsaicin (32 μg/mL). Abbreviations: Cap, capsaicin; Col, colistin; DMSO, dimethyl sulfoxide.
