RESUMEN
We have determined the in vitro activity of antifungal, antibacterial, and antiprotozoal drugs alone and in combination against seven Conidiobolus lamprauges clinical isolates. The assays were based on the M38-A2 protocol and the checkerboard microdilution method. The lowest inhibitory concentrations were observed for amphotericin B, miconazole (MCZ), terbinafine, and miltefosine (MTF) (MIC range 0.25-1; 2-8; 0.25-2; 2-16 µg/ml, respectively). The main synergism observed was through the combination of azithromycin (AZI)+MTF and dapsone (DAP)+MTF (100%), AZI+DAP (85.7%), AZI+MCZ (57.1%) as well as MCZ plus CTX and DAP (42.9%). The in vitro activities suggest that the combination of MTF and AZI or DAP are promising candidate therapies for conidiobolomycosis.
