The fungusSaprochaete capitata causes opportunistic human infections, mainly in immunocompromised patients with hematological malignancies. The best therapy for this severe infection is still unknown. We evaluated thein vitro killing activity and thein vivo efficacy of posaconazole at 5, 10, or 20 mg/kg twice a day (BID) in a murine neutropenic model of systemic infection withS. capitata by testing a set of six clinical isolates. Posaconazole showed fungistatic activity against all of the isolates tested. The different doses of the drug, especially the highest one, showed good efficacy, measured by prolonged survival, reduction of (1-3)-β-d -glucan levels in serum, tissue burden reduction, and histopathology.
