Table 1.
The effectiveness of the tested antimicrobials against K. pneumoniae biofilm formed on the surface of polystyrene in an artificial urine medium with glucose (AUMg). Minimal biofilm eradication concentration (MBEC) values are expressed in mg/L; the % values represent the survival rate at 256 mg/L; X indicates no effect of the maximum tested concentration.
