Dose-response curve of Candida spp. treated with (a) green propolis ethanolic extract, (b) green propolis ethanolic extract pretreated with ultrasound, (c) red propolis ethanolic extract and (d) red propolis ethanolic extract pretreated with ultrasound. Microdilution assays were performed in duplicate. Candida spp. were incubated with a range of propolis concentrations (8 to 0.015 mg/mL) for 48 h. Then, the relative growth was obtained using a spectrophotometer (625 nm), and the growth inhibition rates were calculated. Graphical representations and dose-response stimulation statistics were obtained using the software Graph Pad Prism 6
