The A. nidulans clinical isolates are more sensitive to the cell wall-perturbing agents. (A to C) Strains were grown from 105 spores on glucose minimal medium supplemented with increasing concentrations of caspofungin, Congo red, and calcofluor white for 5 days at 37°C. Standard deviations represent biological triplicates in a two-way ANOVA test, comparing growth of the clinical isolates to growth of the FGSC A4 reference strain (*, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001).
