...Police. For 250 years quinine was the only police agent used to control malaria. Swamp drainage and screening of buildings have been added to the force since 1898, when it was shown that malaria parasites (tiny protozoa of the genus Plasmodium) spend part of their life cycle in female Anopheles mosquitoes. The mosquito picks up the parasites from infected humans, nurtures them and injects them into fresh victims. The parasites run through the bloodstream of their victim, causing periodic fevers at the peak of their reproductive cycle; many lodge in the spleen, causing local pain...
Next problem was to find a human to check the experiment on. The parasite that causes monkey malaria (Plasmodium cynomolgi) is like the parasite that causes most human malaria (Plasmodlum vivax"). He found a mental patient who was about to be given malaria anyway for treatment of general paralysis. The patient and his wife agreed that doctors could take out a small piece of his liver by a minor operation, seven days after he had been bitten by infected mosquitoes. At 5 o'clock one morning Dr. Shortt got the sliver of liver, rushed to his laboratory and worked...
...School researchers reported that they were getting warm. In a paper so important that it got a prize from the American Association for the Advancement of Science, they announced that they had bred in a test tube two types of animalcules. One causes malaria in monkeys and the other (Plasmodium vivax...
...protozoa which cause the disease are carried by about 60 kinds of mosquitoes and are of four main varieties, each producing its own form of malaria: 1) Plasmodium vivax produces the mildest disease, benign tertian malaria; 2) P. malariae bring on quartan malaria, the most difficult to eradicate; 3) P. falciparum produces dangerous malignant tertian malaria; 4) P. ovale produces symptoms similar to those of benign tertian malaria...
Malaria, the most widespread and destructive, is caused by a microscopic parasite, the Plasmodium, carried by many species of the Anopheles mosquito. The chills, fever and delirium of malaria may recur for many years. Malaria can be treated by constant doses of quinine, and a newer drug, stabrine. But there is no immunization against malaria. Warned Dr. Meleney: "We may expect a tremendous morbidity and mortality from malaria in the armed forces during the present conflict...
