Studies on the chemical nature of bacterial O antigens

Chemical Studies on Bacterial Agglutination

1. A method, conforming to the criteria of quantitative analytical chemistry, is described for the estimation of the agglutinin content of antisera. Examples are given of the application of the method to various antipneumococcus sera. 2. This new, absolute method is discussed with regard to its relation to the commonly used relative methods.

Immunological and chemical studies of the streptococcal group O protein type antigens.

Two antigens present in group O streptococci have been described and are designated as type antigens. No other antigens are present in extracts of group O cells in significant quantity. Antigen I is a cell wall protein, and II is a nucleoprotein of undetermined cell location. The immunological specificity of the latter resides only in the protein. Both antigens have been extracted from the cell...
