FIG 3.

Comparison of MBT ASTRA and microdilution results for 51 clinical C. albicans isolates and 57 clinical C. glabrata isolates. For each strain, the MIC obtained by microdilution (x axis) was plotted against the MIC value derived by MBT ASTRA (y axis). The colored boxes indicate the MIC ranges according to CLSI breakpoint; green, susceptible; gray, intermediate; and red, resistant. The horizontal dashed line indicates the breakpoint concentration defined for the MBT ASTRA MIC. (a) For C. albicans, total agreement was observed between the two approaches. (b) For C. glabrata, concordant results were observed for 53 strains by the two methods. Only one susceptible strain was detected as resistant and two resistant isolates were misclassified as susceptible by MBT ASTRA.
