Abstract
A substantially pure capsular exopolysaccharide adhesin of coagulase-negative staphylococcal strains, and a gonoral method to prepare such adhesins, are described. Vaccines composed of such adhesins, and uses of such adhesins to produce polyclonal and monoclonal antibodies against such adhesins, are also disclosed. The adhesins are useful in coating polymoric medical materials to prevent colonization by coagulase-negative staphylococcal strains, and as a probe in selecting desirable polymeric medical materials. Such adhesin antibodies are useful in vivo to prevent infection by nosocomial coagulase-negative staphylococcal strains, in assays for the detection of such bacteria, in assays for the estimation of such adhesins in complex mixtures, and as an affinity chromatography matrix.
