Micafungin activity against Candida bloodstream isolates: effect of growth medium and susceptibility testing method

An excellent correlation between micafungin MICs were demonstrated against Candida bloodstream isolates (n = 200) by the Sensititre YeastOne and National Committee for Clinical Laboratory Standards M27-A2 methods. Use of antibiotic medium 3 (2%) dextrose improved micafungin activity and was not associated with paradoxical growth as noted with 3 Candida isolates tested using RPMI (2%) dextrose.
