Popis: Minimum fungicidal concentration (mFC) of caspofungin was determined against 16 Candida albicans and 16 C. krusei in Rpmi-1640 and antibiotic medium 3 (Am3). time-kill tests were performed on six C. albicans and four C. krusei strains at 0.06-16 mg/l caspofungin. mFC ranges after 48 h were 0.5-1 and 1-2 mg/l for C. albicans and C. krusei, respectively; one C. albicans and the C. krusei reference strain showed paradoxical growth (pG) in Rpmi-1640, respectively. in killing experiments, after 48 h caspofugin was fungicidal against two and four C. albicans in Rpmi-1640 (at 16 mg/l) and in Am3 (at0.5 mg/l), respectively; pG was noted in three and two cases, respectively. Caspofungin at2 and 0.5 mg/l was fungicidal against all tested C. krusei strains even after 24 h in Rpmi-1640 and Am3, respectively. Killing activity of caspofungin against C. albicans and C. krusei could be exactly measured only by killing curves.
