Type I Pneumococcus Otitis Media
History: A student nurse, aged 20, was admitted to the New Haven Hospital on October I3, I929, with a complaint of "earache". There was no history of exposure to Type I pneumococcus infection. One week before admission she developed a dry, nonproductive cough with an uncomfortable restricted feeling about the chest. There was no sore throat nor history of muscular or joint pains. On the morning...
متن کاملA Type Specific Substance Distinct from the Specific Carbohydrate in Pneumococcus Type I
1. Evidence has been presented for the existence of a substance distinct from the specific carbohydrate in the autolytic products of Pneumococcus Type I. 2. The substance reacts specifically by precipitating homologous antiserum which either occurs naturally without antibody against the specific carbohydrate or has been deprived of that antibody artificially. 3. In guinea pigs passively sensiti...
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 کاملSpecific and Non-specific Polysaccharides of Type Iv Pneumococcus
1. Three nitrogen-containing polysaccharides have been isolated from autolyzed cultures of Type IV pneumococcus: (1) a type-specific carbohydrate differing markedly from those of Type I, II, and III pneumococcus, and representing a type of substance hitherto not observed among specific polysaccharides, (2) a chemically similar carbohydrate without specific function, and (3) the "C" substance, o...
متن کاملA Type-specific Protein from Pneumococcus
The isolation and characterization of a type-specific M protein from pneumococcus are described. This protein is similar chemically in all respects studied to the M proteins of group A streptococci. No immunological crossreactions have been observed, however, between M proteins of the two species. Strains of capsular type I pneumococcus have been encountered which contain different M proteins. ...
