Broth microdilution testing was used. The MICs for Candida species were determined as the minimum concentration resulting in at least 80% inhibition of growth of Candida species measured as a decrease in turbidity compared with the turbidities of the growth controls. The MICs for A. fumigatus were determined as the minimum concentration resulting in a prominent decrease in turbidity compared with the turbidity of the growth control.
Incubation was for 48 h at 35°C.
Incubation was for 72 h at 35°C.
