Measurement of human antibodies to type III group B Streptococcus.
We disagree with the conclusions reached by Bhushan et al. (5) in their study comparing different methods of coating enzyme-linked immunosorbent assay (ELISA) plates for estimation of group B Streptococcus type III (GBS III) polysaccharide-specific antibody concentrations in human serum. We believe that interpretation of the data as suggested in their paper could lead to serious errors in the u...
متن کاملImmunogenicity of polysaccharides from type III, group B Streptococcus.
The immunogenicity and safety of two polysaccharides isolated from type III, group B Streptococcus, were tested in adults selected for existing low concentrations of natural antibody to the capsular polysaccharide of this organism. Both vaccine preparations (trichloroacetic acid and EDTA) were found to lack pyrogenicity and toxicity for experimental animals. A single 50-microgram subcutaneous i...
متن کاملMouse protection test for group B Streptococcus type III.
The mouse model has been used previously for the study of protection against challenge with strains of group B Streptococcus types Ia, Ib, and Ic, but investigators have not yet been successful in causing lethal disease when type III strains are inoculated. In this study, six clinical isolates belonging to serotype III were lethal in seven-week-old outbred albino mice; the 50% lethal dose (LD50...
متن کاملConjugate vaccines against group B Streptococcus types IV and VII.
Although rarely encountered, group B Streptococcus (GBS) types IV and VII have been isolated from infants and adults with invasive disease. This study was designed to determine the immunogenicity and efficacy in animals of conjugate vaccines prepared with GBS types IV and VII capsular polysaccharide (CPS). Despite the striking similarities in structure of these 2 carbohydrate antigens, high-tit...
متن کاملType III group B streptococcal polysaccharide induces antibodies that cross-react with Streptococcus pneumoniae type 14.
Covalent linkage of a bacterial polysaccharide to a protein greatly enhances the carbohydrate's immunogenicity and its binding to solid surfaces in immunoassays. These findings have spurred the development of glycoconjugate vaccines to prevent serious bacterial infections as well as the use of glycoconjugates as coating antigens in bioassays. We evaluated sera from women immunized with unconjug...
