Effect of antifungal treatment in a murine model of blastoschizomycosis.

Blastoschizomyces capitatus is an emerging pathogenic fungus that can cause deep invasive diseases in neutropenic patients. We developed a model of disseminated blastoschizomycosis in immunosuppressed mice to evaluate the effectiveness of amphotericin B, flucytosine, fluconazole and voriconazole. High-dose fluconazole was the most effective drug at prolonging the survival of mice and at reducing fungal burden in the kidneys, spleen and liver.
