Surface properties of Staphylococcus saprophyticus: hydrophobicity, haemagglutination and Staphylococcus

Abstract:
Cell surface hydrophobicity may contribute to virulence in urinary tract pathogens. In this study we assess the influence of differential expression of the two major surface proteins (Ssp and the haemagglutinin) of Staphylococcus saprophyticus on cell surface hydrophobicity. The haemagglutinating strain CCM883, which does not produce Ssp, was hydrophobic regardless of the growth conditions. Strain 9325, which is non-haemagglutinating and produces Ssp, was hydrophobic only when grown in liquid media. Although these results suggest an association between the ability to express the haemagglutinin and the structure responsible for cell surface hydrophobicity, they refute any major role of Ssp and haemagglutinin in hydrophobicity. Treatment of bacteria with proteases reduces hydrophobicity, indicating that the structure mediating hydrophobicity is a protein.
