Co-dosing concentration curves. IC50 curves for the inhibition of V. cholerae biofilms by compound 5 alone shown in blue. Shown in red are the IC50 curves for the inhibition of V. cholerae biofilms treated with varying concentrations of compound 5 plus treatment with a fixed concentration of A) tetracycline at 0.19 μM, B) ceftazidime at 222 μM, and C) ciprofloxacin at 0.037 μM. Ceftazidime was shown to be weakly effective against as an antibiotic against the strain of V. cholerae used in this study, reflecting the seemingly high sub-MIC and sub-BIC concentration.
