Fig. (1) Drug susceptibility assays against C. albicans in the presence of MB.(a) Spot assay of C. albicans reference strains (ATCC 10261) and clinical isolates (D1, D2) in the absence (control) and presence of MB. (b) Disc diffusion assay against C. albicans reference strains (ATCC 10261) and clinical isolates (D1, D2) of C. albicans and their respective zone of inhibitions in the absence (control) and presence of MB. For control, discs were spotted with the solvent of MB (water) (c) Broth microdilution assay to determine the MIC80 of C. albicans reference strains (ATCC 10261) and clinical isolates (D1, D2) in presence of MB. Data is quantitatively displayed with colour (see colour bar), where each shade of colour represents relative optical densities of the cell. The minimum drug concentration that inhibits growth by 80% relative to the drug-free growth control is indicated as MIC80 for each strain.
