The Capsular Polysaccharide of Pneumococcus Type Ix
The capsular polysaccharide of Type IX pneumococcus contains D-glucose, N-acetyl-D-glucosamine, and D-glucuronic acid. Complete hydrolysis is difficult. All of the N-acetylglucosamine is resistant to oxidation by periodate, but the other two sugars are degraded in part. Chemical and quantitative serological data are consistent with the linkage of two D-glucose residues 1 --> 4, as in maltose; o...
متن کاملPneumococcal Capsular Polysaccharide Vaccine
Streptococcus pneumoniae (pneumococcus [Pnc]) is a common bacterial agent found in mild mucosal as well as severe systemic infections. Local infections, such as acute otitis media, are rather common; every child has at least one during the first 2 years of life (1), and Pnc is the causative agent in approximately half of the bacterial culturepositive cases (2). Pneumonia is another disease ofte...
متن کاملA conjugate vaccine composed of a heat shock protein 60 T-cell epitope peptide (p458) and Neisseria meningitidis type B capsular polysaccharide.
Neisseria meningitidis type B is a major world-health problem. The Meningococcus type B capsular polysaccharide (MnB) is very poorly immunogenic and no vaccine to the antigen exists. Here, we conjugated the MnB to a T-cell carrier peptide (p458) derived from the self-60kDa heat shock protein molecule. The conjugate vaccine was effective in inducing long-lasting IgG antibodies to the MnB antigen...
متن کاملTherapeutic efficacy of a conjugate vaccine containing a peptide mimotope of cryptococcal capsular polysaccharide glucuronoxylomannan.
Vaccination with P13, a peptide mimotope of the cryptococcal capsular polysaccharide glucuronoxylomannan (GXM), has been shown to confer protection against a subsequent lethal Cryptococcus neoformans challenge. In this study, we sought to investigate whether P13-based vaccines could be effective in an already-established infection. To address this question, we developed a systemic chronic crypt...
متن کاملDecomposition of the Capsular Polysaccharide of Pneumococcus Type Iii by a Bacterial Enzyme
1. An organism has been isolated from peat soil which decomposes the specific capsular polysaccharide of Type III Pneumococcus. 2. The isolation has been made possible by the use of a synthetic mineral medium containing the specific polysaccharide as sole source of carbon. By repeated transfers in this medium the potential capacity of the organism to decompose the specific substance has been pr...
