The BacT/Alert blood culture system was evaluated for the MIC determination of amphotericin B for 27 strains of Aspergillus from five different species. An inoculum of c. 108 cfu/mL and an incubation time of 48 h resulted in MICs for 26 of 27 strains that corresponded with published MICs obtained in a microdilution assay. Twelve of 13 strains with MIC48 values
2 mg/L showed growth within 24 h in bottles containing 0.25 mg/L amphotericin B, indicating that results can be obtained the day following inoculation. It is concluded that the BacT/Alert blood culture system can be used for susceptibility testing of Aspergillus spp. with amphotericin B.
