Surface proteins from coagulase-negative staphylococci and Staphylococcus aureus that generate cross-reactive monoclonal and polyclonal antibodies

摘要

Surface proteins are provided which generate polyclonal and monoclonal antibodies which are cross-reactive to both coagulase-positive staphylococcus bacteria, such as S. aureus and to coagulase-negative bacteria, such as S. epidermidis and S. hemolyticus. The antibodies may be generated from surface proteins that have been isolated on the basis of characteristics that may be common between S. aureus and coagulase-negative staphylococci, or the A domains of those surface proteins, and these recombinant surface proteins are used to generate the cross-reactive antibodies. Vaccines comprising an immunologically effective amount of the proteins are also provided, and these vaccines are used in methods for the treatment or protection against a wide variety of staphylococcal infections.
