| 摘要 |
A substantially pure capsular exopolysaccharide adhesin of coagulaso-negative staphylococcal strains, and a general method to prepare such adhesins, are described. Vaccines composed of such adhesins, and uses of such adhesins to produce polyclonal and mono-clonal antibodies against such adhesins, are also disclosed. The adhesins are useful in coating polymeric 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 noso-comial 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.
