摘要:
The present invention relates to immunogenic compositions, comprising polypeptides and polysaccharides from Staphylococcus aureus. The present invention also relates to immunogenic compositions, comprising Staphylococcus aureus capsule polysaccharides conjugated to a carrier protein. In addition, the invention relates to methods of inducing an immune response in subjects against Staphylococcus aureus using immunogenic compositions of the Staphylococcus aureus polypeptides and capsule polysaccharides.
摘要:
An isolated, altered fibronectin-binding protein (Fnb) of S. aureus having at least one mutation in an amino acid selected from residues corresponding to Gln103, Gln105, Lys157, Lys503, Lys620, Lys702, Lys762, Gln783 and Gln830 of FnbA of S. aureus strain ATCC49525 is described. Replacement of these reactive residues within the fibronectin-binding protein renders this protein less capable than wild-type Fnb of covalently cross-linking with fibronectin and fibrin. The altered fibronectin-binding protein effectively interferes with adhesion of S. aureus to fibronectin and fibrin, and therefore, an immunogenic composition comprising such altered Fnb exhibits improved immunogenic properties and is safer to use.
摘要:
Immunogenic polysaccharide-protein conjugates having a polysaccharide antigen (or its oligosaccharide fragment representing one or more antigenic epitopes) derived from a nosocomial pathogen conjugated to a staphylococcal surface adhesin carrier protein are used in immunogenic compositions to elicit antibody responses to both the polysaccharide antigen and the staphylococcal surface adhesion carrier protein. Such immunogenic compositions are used to immunize against diseases caused by Staphylococcal aureus, Staphylococcal epidermidis or other nosocomial pathogens.

The present invention relates to immunogenic compositions, comprising polypeptides isolated from Staphylococcus epidermidis. The invention also relates to polynucleotides encoding Staphylococcus epidermidis polypeptides and their use in immunogenic compostions. In addition, the invention relates to methods of inducing an immune response in mammals against Staphylococcus epidermidis and Staphylococcus aureus using immunogenic compostions of the Staphylococcus epidermidis polypeptides and polynucleotides. The invention also relates to methods for detecting Staphylococcus epidermidis in a biological sample.
