Abstract

Adhesion of four isolates of Candida albicans to buccal epithelial cells was determined after growth of the yeasts in defined medium containing 50 mM glucose or 500 mM galactose as the carbon source. With each isolate, adhesion of galactose-grown yeasts was significantly higher than that of glucose-grown organisms. Yeast cell-surface hydrophobicity was assessed by two methods, a modified hydrocarbon adhesion assay and a more sensitive polystyrene microsphere assay. All four isolates were significantly more hydrophobic after growth on 500 mM galactose than after growth on 50 mM glucose. Overall, a strong positive correlation between adhesion and surface hydrophobicity was observed (r= 0.965). These results are discussed in relation to the role of yeast-surface hydrophobicity in pathogenesis.
