Detection of Staphylococcus aureus infection by enzyme-linked immunosorbent assay and immunoblotting, using high molecular weight staphylococcal proteins.

Two high molecular weight staphylococcal proteins, fibronectin-binding protein and a Mr 200,000 protein, were investigated as antigens for serodiagnosis of staphylococcal infections. Sera from patients with staphylococcal infections and from controls were subjected to immunoblot analysis with staphylococcal lysate proteins to identify staphylococcal antigens to which patients with staphylococcal infections specifically exhibited antibodies. One such protein was found in the Mr 200,000 region. This protein was purified and used as antigen in ELISA and compared with other antigens, namely fibronectin-binding protein(s) (FNBP, Mr 185,000), alpha-toxin and teichoic acid. Sera from patients with staphylococcal infections contained antibodies to the high molecular weight proteins in higher titers than sera from patients with non-staphylococcal infections or healthy subjects. Based on their amino-acid compositions and different abilities to bind fibronectin it was concluded that the Mr 200,000 protein and FNBP were not identical.[1]
