We investigated the relevance of prominent reduction in turbidity
macroscopically (MIC) and formation of aberrant hyphal tips microscopically (minimum effective concentration; MEC) in measuring the
in vitro activity of caspofungin against Aspergillus and
Fusarium. Caspofungin generated low MICs and MECs against
Aspergillus, but not for Fusarium. While MICs
increased inconsistently when the incubation time was prolonged, MEC
appeared as a stable and potentially relevant endpoint in testing in
vitro caspofungin activity.
