Graphical three-dimensional presentation comparing the observed (colored mesh) and the calculated simulated (vertical bars) anti-biofilm potentials of variable concentrations of ceftazidime/colistin (a and b) and gentamicin/meropenem (c and d) combinations. Results showed a lower bacterial burden (higher antibacterial potential) in the case of the observed data as compared to the simulated one under an assumption of null interaction between the combined antibiotics
