  • Patent number: 7850974
    Abstract: A bioinformatic method for identifying and isolating proteins and peptides with MSCRAMM®-like characteristics from Gram positive bacteria, such as Enterococcus, Staphylococcus, Streptococcus and Bacillus bacteria, and proteins and peptides obtained thereby are provided which can be utilized in methods to prevent and treat infections caused by Gram-positive bacteria. The method involves identifying from sequence information those proteins with a putative C-terminal LPXTG (SEQ ID NO:1) cell wall sorting signal and other structural similarities to MSCRAMM® proteins having the LPXTG-anchored cell wall proteins. The MSCRAMM® proteins and immunogenic regions therein that are identified and isolated using the present invention may be useful in the diagnosis, treatment or prevention of Gram positive bacterial infections.

  • Patent number: 7615616
    Abstract: A bioinformatic method is provided for identifying and isolating proteins with MSCRAMM®—like characteristics from Gram positive bacteria, such as Enterococcus, Staphylococcus, Streptococcus and Bacillus bacteria, which can then be utilized in methods to prevent and treat infections caused by Gram-positive bacteria. The method involves identifying from sequence information those proteins with a putative C-terminal LPXTG (SEQ ID NO:1) cell wall sorting signal and other structural similarities to MSCRAMM® proteins having the LPXTG-anchored cell wall proteins. The MSCRAMM® proteins and immunogenic regions therein that are identified and isolated using the present invention may be used to generate antibodies useful in the diagnosis, treatment or prevention of Gram positive bacterial infections.

  • Patent number: 6288214
    Abstract: Disclosed are the cna gene and cna-derived nucleic acid segments from Staphylococcus aureus, and DNA segments encoding cna from related bacteria. Also disclosed are Col binding protein (CBP) compositions and methods of use. The CBP protein and antigenic epitopes derived therefrom are contemplated for use in the treatment of pathological infections, and in particular, for use in the prevention of bacterial adhesion to Col. DNA segments encoding these proteins and anti-(Col binding protein) antibodies will also be of use in various screening, diagnostic and therapeutic applications including active and passive immunization and methods for the prevention of bacterial colonization in an animal such as a human. These DNA segments and the peptides derived therefrom are contemplated for use in the preparation of vaccines and, also, for use as carrier proteins in vaccine formulations, and in the formulation of compositions for use in the prevention of S. aureus infection.
