摘要:
The present invention relates to immunogenic conjugates comprising S. aureus serotype 5 and 8 capsular polysaccharides conjugated to carrier proteins and methods for their preparation and use. Methods for making the immunogenic conjugates of the invention involve covalent conjugation of the capsular polysaccharides with the carrier proteins using conjugation chemistry involving either 1,1-carboyl-di-1,2,4-triazole (CDT) or 3-(2-pyridyldithio)-propionyl hydrazide (PDPH).

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:
A negatively-charged Staphylococcus antigen contains amino acids and a N-acetylated hexosamine as a major carbohydrate component. The antigen is common to many coagulase-negative strains of Staphylococcus, including S. epidermidis, S. haemolyticus, and S. hominis. Staphylococcus strains that carry the antigen include many clinically significant strains of Staphylococcus. The antigen and antibodies to the antigen are useful in kits and assays for diagnosing Staphylococcus infection. Vaccines of the antigen and of whole cells that carry the antigen also are disclosed.
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.
