Anaphylaxis in Pneumococcus Immunity
That bacterial derivatives possess anaphylactogenic properties was demonstrated by the pioneers in the study of anaphylaxis. But from the numerous subsequent studies in bacterial hypersensitiveness the fact has emerged that these antigens are not highly endowed with anaphylactogenic properties. Compared to such substances as egg albumin and animal serums bacterial derivatives yield positive res...
متن کاملStudies on Pneumococcus Immunity
1. Active immunity against many lethal doses of Pneumococcus Types I, II, and III may be produced in mice by two or three subcutaneous injections of the homologous type of pneumococcus saline vaccine. 2. Mice may be actively immunized with the protein fraction obtained by treating pneumococci with anhydrous sodium sulfate or by solution of pneumococci in bile salts and precipitation with alcoho...
متن کاملImmunity Factors in Pneumococcus Infection
The varied native resistance that different animal species, or individuals of the same species, offer to bacterial infection has been the object of much investigation and also of speculation. This has naturally arisen from the a priori fact that a thorough knowledge of nature's methods of combating infections is an indispensable prerequisite of a successful treatment of infectious diseases. In ...

متن کاملThe Significance of Anaphylaxis in Pneumococcus Immunity
1. Intraperitoneal injections of killed and living broth cultures of a virulent pneumococcus produce in guinea pigs a high degree of active immunity and a serum with strong protective power. 2. Despite the protective power of such serum no agglutinins for the homologous organism and no precipitins for soluble derivatives were demonstrable. 3. Guinea pig immunity to pneumococcus infection produc...
