PRODUCTION IN MONKEYS OF COMPLEMENT-FIXING ANTIBODIES WITHOUT ACTIVE IMMUNITY BY INJECTION OF KILLED PLASMODIUM KNOWLESI.
Injection into rhesus monkeys of Plasmodium knowlesi killed by heat, formalin, drying, or freezing and thawing stimulates the production of complement-fixing antibodies, but no demonstrable agglutinating or protective antibodies are formed. Possible differences in the immunity mechanisms concerned in active infection and in artificial immunization are discussed.
