[The interaction of staphylococci with plasmin and its inhibitors]

According to the data obtained by immunoblotting and other immunochemical techniques, the cell wall of Staphylococcus aureus, strain 209 P, contain proteinaceous receptors for plasminogen, plasmin and its complexes with alpha 2 glycoprotein and protein A, alpha 2 proteinase inhibitor, alpha 2 antiplasmin. Strains Cowan 1 and Wood 46 have no such receptors. All three strains have been found to contain the receptor for alpha 2 interferon, its molecular weight being equal to 50 kD.
