FIG 1.

C. albicans biofilms are altered in the presence of HHQ. Filamentous C. albicans biofilms grown in the presence of PQS and HHQ (100 μM) were assessed structurally by confocal microscopy and metabolically using the XTT biofilm assay. The data (means and standard errors of the mean [SEM]) are representative of three independent biological experiments and are presented relative to the untreated control. A two-tailed paired Student t test was performed by comparison of C. albicans in the presence of HHQ and PQS with C. albicans treated with methanol or ethanol (**, P ≤ 0.01; ***, P ≤ 0.001).
