In order to get information as to whether direct interaction of H. pylori and yeasts may modulate the course of H. pylori infections, the adhesion of H. pylori to C. albicans, C. glabrata, C. guilliermondii, C. krusei, C. parapsilosis, C. tropicalis and S. cereviseae was investigated. H. pylori adhered significantly more frequently to C. tropicalis (adhesion ratio > 10%) than to the other yeasts (adhesion ratios < 5%). On an average, no significant difference to the adhesion ratios of E. coli and S. aureus was found. Electron microscopic examinations showed that H. pylori cells contacted the cells of C. tropicalis either by knob-like structures or by close surface-to-surface adhesion. Cholesterol-depleted H. pylori cells adhered to the yeast no more than cholesterol-carrying cells. There was no indication that a direct cooperation with yeasts plays a role in H. pylori infections.
