WebUtilizing eight different bacterial pathogens, we demonstrate that this method is widely applicable for biofilm quantification. Depending on the species, this biofilm assay offered a large dynamic range of 8-146 fold change compared to 2-22 fold for crystal violet staining under similar conditions. WebNov 3, 2024 · The MBEC was defined as the minimal concentration of antibiotic required to reduce biofilm cell numbers below detection limit of the assays used (i.e. 10 6 CFU/mL for resazurin-based assay and 10 2 CFU/mL for cell counting method). We also consider that a successful biofilm eradication should be complete, thus there is no bacterial survivors to ...
