Abstract

Caspofungin activity was determined in vitro and in vivo against three Candida orthopsilosis, three C. metapsilosis, two C. parapsilosissensu stricto and two C. albicans isolates. MIC values and killing activity were determined in RPMI-1640 plus 50 % human serum. Neutropenic (cyclophosphamide-treated) mice were infected intravenously. Five-day intraperitoneal treatment with caspofungin was started after 24 h postinfection. Kidney burden was analyzed using the Kruskal-Wallis test with Dunn's post-test. In killing studies, caspofungin was fungistatic and fungicidal against C. albicans at ≥0. 25 and ≥2 μg/ml concentrations, respectively. Caspofungin was fungistatic at ≥8-16, ≥2-8 and at ≥2-8 μg/ml against C. parapsilosis, C. orthopsilosis and C. metapsilosis, respectively. In the murine model, C. albicans was inhibited by 1, 2 and 5 mg/kg of caspofungin (P <0. 001 compared to the controls). Against C. parapsilosis, only 5 mg/kg caspofungin was effective against both isolates (P <0. 05). Two and five mg/kg of caspofungin was effective against all C. orthopsilosis and C. metapsilosis isolates (P <0. 05 to
