    Notes: Staphylococcus aureus has been shown to interact specifically with fibrinogen. Three different extracellular fibrinogen-binding proteins, two of which have coagulase activity, are produced by S. aureus strain Newman. The role of these fibrinogen-binding proteins during staphylococcal colonization and infection has not yet been fully elucidated. Here we describe the cloning, sequencing and expression of a gene for a 19kDa fibrinogen-binding protein. This gene, called fib, encodes a 165-amino-acid polypeptide, including a 29-amino-acid signal sequence. The recombinant protein, which has an estimated molecular mass of 15.9kDa, bound fibrinogen and was recognized by a polyclonal antiserum against the native Fib protein. Homologies between the Fib protein and the fibrinogen-binding domain of coagulase suggest that amino acids within this domain are involved in the binding to fibrinogen.

    Notes: Abstract A mouse mastitis model was used to study the effect of vaccination with fibrinogen binding proteins and collagen binding protein from Staphylococcus aureus against challenge infection with S. aureus. The mice vaccinated with fibrinogen binding proteins showed reduced rates of mastitis compared with controls. Gross examination of challenged mammary glands of mice showed that the glands of mice immunized with fibronogen binding proteins developed mild intramammary infection or had no pathological changes compared with glands from control mice. Histopathological examination of tissue sections from challenged glands showed that most glands from mice vaccinated with fibrinogen binding protein developed disseminated necrosis or had no pathological changes. A significantly reduced number of bacteria could be recovered in the glands from mice immunized with fibrinogen binding proteins as compared with controls. In a similar study, immunization of mice with collagen binding protein did not induce protection against challenge infection with S. aureus.
