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 کاملImmunological Studies on a New Preparation of Type Specific Polysaccharide from Pneumococcus Type I
A type specific polysaccharide has been isolated from the autolyzed broth of Type I Pneumococcus by a modified Avery and Goebel's method. The newly prepared polysaccharide reacts with the homologous immune rabbit serum which has been completely absorbed with the acetyl polysaccharide of Avery and Goebel. The newly prepared polysaccharide produces passive immunity in mice and rats and possibly i...
متن کاملAbsence of a Prosthetic Group in a Type-specific Polysaccharide of Pneumococcus
The specific polysaccharide of Type III pneumococcus, with only 0.05 per cent of N and 0.01 per cent of P, still shows almost maximal precipitation of a Type III antipneumococcus rabbit serum and the expected antigenicity in man. There is therefore no evidence that a prosthetic group is involved in these characteristic activities.
متن کاملThe Soluble Specific Substance of Pneumococcus. v. on the Chemical Nature of the Aldobionic Acid from the Specific Polysaccharide of Type Iii Pneumococcus
The so called soluble specific substances of the three fixed types of Pneumococcus appear identical with three chemically distinct, serologically type specific polysaccharides produced by these organisms during growth in culture media (1). The immunological significance and the chemical nature of these bacterial carbohydrates have been discussed in detail in earlier publications from this labor...
متن کاملThe Value of the Skin Test with Type-specific Capsular Polysaccharide in the Serum Treatment of Type I Pneumococcus Pneumonia
Skin tests were made with Type I S.S.S. in 53 cases of Type I pneumococcus lobar pneumonia, 48 of which were treated with antipneumococcus Type I serum. In all but 1 of the 46 recovered cases a positive, immediate skin reaction was obtained at about the time of recovery. In 7 fatal cases reactions were consistently negative, even in the presence of circulating type-specific antibodies. The skin...
