Fig 1. Drug susceptibility assays against C. albicans and non-albicans species of Candida in the presence of PA.

(a) Broth microdilution assay to determine the MIC₈₀ of C. albicans reference strain SC5314, clinical isolates (D1, D2, D4, D7, D18 and D20) and C. glabrata, C. krusei, C. parapsilosis and C. tropicalis in presence of PA. Data was quantitatively displayed with color (see color bar), where each shade of color 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. (b) Spot assay of C. albicans reference strain SC5314, clinical isolates (D1, D2, D4, D7, D18 and D20) and C. glabrata, C. krusei, C. parapsilosis and C. tropicalis in the absence (control) and presence of PA.
