*Pseudomonas aeruginosa strains with discordant synergy results. (a)Performed in triplicate. (b)Values represent the log10 change in CFU/mL in the time-kill assay after 24 hour exposure to the combination of levofloxacin (LVX) and piperacillin/tazobactam (TZP) compared to the most active drug alone. Negative values indicate a decrease in colony count; positive values indicate an increase in colony count. S: synergy; I: indifference. |
