ANTIBLASTIC IMMUNITY
1Hospital of The Rockefeller Institute for Medical Research.
Antipneumococcus serum inhibits pneumococci multiplication and metabolic functions. This inhibitory power, termed antiblastic immunity, appears in human serum during lobar pneumonia crisis.
Area of Science:
- Immunology
- Microbiology
- Biochemistry
Background:
- Pneumococci are bacteria that cause pneumonia.
- Antipneumococcus serum is a potential therapeutic agent.
- Understanding bacterial inhibition mechanisms is crucial for treating infections.
Purpose of the Study:
- To investigate the inhibitory effects of antipneumococcus serum on pneumococci.
- To characterize the functions inhibited by the serum.
- To define the phenomenon of antiblastic immunity.
Main Methods:
- Observational study of antipneumococcus serum.
- Assay of pneumococci growth inhibition.
- Analysis of pneumococci proteolytic and glycolytic functions.
- Serum analysis during lobar pneumonia crisis.
Main Results:
- Antipneumococcus serum inhibits pneumococci multiplication.
- Serum also inhibits pneumococci proteolytic and glycolytic functions.
- These inhibitory powers emerge or increase in human serum during lobar pneumonia crisis.
Conclusions:
- Bacterial growth retardation is linked to metabolic function inhibition by anti-enzymotic substances in antipneumococcus serum.
- The term 'antiblastic immunity' describes this phenomenon.
- This finding has implications for understanding host defense mechanisms in pneumonia.

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
