title: The comparative efficacy of cilofungin, fluconazole and amphotericin B in disseminated Candida tropicalis infection in neutropenic mice.
abstract: There is insufficient in vivo data on the efficacy of new antifungal agents against invasive Candida tropicalis infection. Disseminated infection with Candida tropicalis in neutropenic mice was treated with cilofungin, fluconazole, or amphotericin B intraperitoneally, and compared to untreated controls. Early survival rates at the end of treatment (day 10) were similar for amphotericin B (97.5%) and fluconazole (100%), and superior to cilofungin (62.6%) which was better than no treatment (0%). Late survival rates (day 31) were highest for amphotericin B (95%), and significantly lower for cilofungin (48.7%) and fluconazole (43.9%), p = 0.0001. Rates of sterilization of the lung, liver, and spleen were high in survivors for all regimens (85.1-100%) but lower for the kidneys: fluconazole, 21.3%; amphotericin B, 39.3%; and cilofungin, 65.5%. Amphotericin B was the most effective agent in this study of disseminated Candida tropicalis (C. tropicalis) infection.
