title: Amphotericin B-metronidazole combination against Candida spp.
abstract: Interaction between amphotericin B and metronidazole was studied against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida krusei, and Candida lusitaniae strains. Minimum inhibitory concentrations (MICs) of the drugs alone and in combination were determined by means of the checkerboard method on YNB supplemented agar. Minimum fungicidal concentrations (MFCs) were determined on Sabouraud dextrose agar. Based on the MIC and MFC values, fractionary indices were determined respectively for inhibitory and lethal activities of the amphotericin B-metronidazole combination. These indices showed occurrence of additive and synergistic interactions between the drugs, but the synergysm was predominant against the studied strains.
