Chemoimmunological Studies on the Soluble Specific Substance of Pneumococcus
The soluble specific substance of Pneumococcus Type I has been chemically isolated from the bacterial cells and from autolyzed cultures as an acetyl polysaccharide. So far as could be determined by the methods employed, the acetyl polysaccharide in highly purified form absorbs from Type I antipneumococcus serum all demonstrable type-specific precipitins, agglutinins and protective antibodies. M...
متن کاملThe Soluble Specific Substance of Friedländer's Bacillus
1. Methods are given for the isolation of specifically reacting nitrogen-free polysaccharides from Type A and Type C Friedländer's bacillus. 2. The properties of these specific carbohydrates have been outlined.
متن کاملThe Soluble Specific Substance of Pneumococcus
1. A method is given for the concentration and purification of the soluble specific substance of the pneumococcus. 2. The material obtained by this method is shown to consist mainly of a carbohydrate which appears to be a polysaccharide built up of glucose molecules. 3. Whether the soluble specific substance is actually the polysaccharide, or occurs merely associated with it, is still undecided...
متن کاملTHE SOLUBLE SPECIFIC SUBSTANCE OF FRIED- LiiNDER’S BACILLUS
The methods of isolation and the immunological significance of specific carbohydrates from the three fixed types of Pneumococcus and of Friedlander’s bacillus have been described in a series of communications from this laboratory (1). These unusual polysaccharides, which are believed to be identical with the capsular material of the microorganisms from which they are derived, have been isolated...
متن کاملThe Elaboration of Specific Soluble Substance by Pneumococcus during Growth
1. A specifically reacting substance of bacterial origin is present in the cell-free fluids of young cultures of pneumococcus. This substance is present when the organisms are growing at their maximum rate and undergoing little or no cell death, and consequently its. presence is not dependent upon cell disintegration but represents the extrusion of bacterial substance by the living organism. 2....
