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(More)
The functional r61e of bacterial polysaccharides in immunity has been amply demonstrated in studies from this and other laboratories. Although knowledge of the precise chemical constitution of the bacterial polysac-charides is still meager, it has been possible in some measure to correlate their specific immunological properties with differences in chemical(More)
An apparatus for maintaining the pH of an actively growing bacterial culture at constant level has been described. Using this apparatus it has been shown that the production of maximal amounts of colicine K from a strain of E. coli known as K235 is dependent upon an enriched nutrient medium which is maintained at pH 7.0.
1. When two chemically different carbohydrate derivatives are bound to the same protein, the newly formed antigens exhibit distinct immunological specificity. 2. When the same carbohydrate radical is conjugated with two chemically different and serologically distinct proteins both of the sugar-proteins thus formed acquire a common serological specificity.(More)

1. An artificial antigen containing the azobenzyl glycoside of cellobiuronic acid gives rise in rabbits to antibodies which: (a) give the Neufeld reaction and agglutinate Type III pneumococci, (b) confer passive protection on mice against infection with Types II, III, and VIII pneumococci. 2. Rabbits immunized with the artificial cellobiuronic acid antigen(More)
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,(More)
