Antiblastic Phenomena in Active Acquired Immunity and in Natural Immunity to Pneumococcus
The paper gives the results of a series of experiments made with a special technique for the purpose of testing whether or not so called antiblastic phenomena or bactericidal phenomena play any part in immunity to pneumococcus. The technique employed is that devised by the writer and consists in the isolation of single bacteria and their growth in hanging drops where growth can be continuously ...
متن کاملStudies on Antiblastic Immunity
Antipneumococcus serum under certain conditions apparently inhibits or retards the metabolic activities of the homologous pneumococcus. Antipneumococcus serum exhausted of its agglutinin content possesses no inhibitory properties. The degree of inhibitory action of antipneumococcus serum parallels its agglutinating power. No evidence has been found to indicate that the inhibition of the metabol...
متن کاملAnaphylaxis 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 Natural Immunity to Pneumococcus Type Iii
AMONG THE EXPERIMENTAL FINDINGS REPORTED IN THIS PAPER TO WHICH WE WISH TO GIVE PARTICULAR EMPHASIS ARE THE FOLLOWING: 1. The results which follow the intravenous injection into rabbits of two strains of Pneumococcus Type III of different degrees of virulence vary with the state of the capsule. Thus when this structure is completely developed both remain in the blood. A culture of either strain...
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 ...
