We evaluated the efficacies of posaconazole and voriconazole in comparison with that of amphotericin B in a systemic murine infection by Candida krusei. Posaconazole at 50 mg/kg/day and voriconazole at 40 and 60 mg/kg/day prolonged survival and reduced the fungal tissue burden in the kidneys of mice similarly to amphotericin B at 1.5 mg/kg/day and liposomal amphotericin B at 10 mg/kg/day. None of the treatments tested completely resolved the infection.
