Abstract
Treatment of Helicobacter pylori cells with several chaotropic agents resulted in different degrees of inhibition in the binding of the bacteria to hemin and Congo-red dye. Polyanions also yielded a >50% inhibitory effect. Furthermore, hydrophobic interaction chromatography was used to determine the relative surface hydrophobicity of cell-associated proteins extracted with 3mol/L urea, revealing proteins with a significant hydrophobic profile.
