Patent number: 7968100Abstract: 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.Type: GrantFiled: February 4, 2009Date of Patent: June 28, 2011Assignees: Universita'Degli Studi Di Pavia, Inhibitex, Inc., Provost Fellows and Scholars of the College of the Holy and Undivided Trinity of Queen Elizabeth Near DublinInventors: Timothy Foster, Fiona Roche, Mark Pallen, Joseph M.

Patent number: 7241592Abstract: Antibodies to the CNA protein and to other regions from the collagen binding domain, including domain CNA19, are provided, and antibodies produced in this manner have been shown to be cross reactive to both Staphylococcus aureus and Staphylococcus epidermidis bacteria and which can thus be used in the prevention and treatment of infections caused by both of these types of bacteria. In addition, medical instruments can be treated using the antibodies of the invention in order to reduce or eliminate the possibility of their becoming infected or further spreading the infection. In particular, the proteins are advantageous because they are cross-reactive and may thus be administered to patients so as to reduce or prevent severe infection by staphylococcal bacteria of more than one species.Type: GrantFiled: March 19, 2001Date of Patent: July 10, 2007Assignees: Universita Degli Studi di Pavia, The Texas A&M University System, Inhibitex, Inc.Inventors: Magnus Hook, Yi Xu, Pietro Speziale, Livia Visal, Fabrizia Casolini, Joseph M.

Publication number: 20050202025Abstract: Monoclonal and polyclonal antibodies are provided which can bind to the FbsA protein of Streptococcus agalactiae (GBS) and which can be used to prevent adherence of the bacteria to host cells and thus be useful in the treatment and protection against infection from S. agalactiae. The antibodies of the invention can also be raised against the fibrinogen binding domain of FbsA or the repeat region therein, and in addition to preventing bacterial adherence, the antibodies to FbsA are advantageous in that they can be used to prevent platelet aggregation and thrombus formation.Type: ApplicationFiled: July 23, 2004Publication date: September 15, 2005Inventors: Pietro Speziale, Giampiero Pietrocola, Livia Visai
