Flow cytometry antifungal susceptibility testing of Aspergillus fumigatus and comparison of mode of action of voriconazole vis-à-vis amphotericin B and itraconazole.
Aspergillus fumigatus isolates were tested with three antifungals by flow cytometry (FC) and fluorescence-activated cell sorting. FC results after 4 h correlated well with MICs obtained by the NCCLS M38-A method; voriconazole exhibited fungicidal activity, albeit to a lesser extent than amphotericin B, but to a greater extent than itraconazole.
