Last week Bacteriologist Hermann Dostal of Vienna announced that he had isolated the leprosy bacillus, developed a serum. One problem which has always confronted scientists attempting to isolate the bacillus has been a means of keeping it alive once it was removed from the human body. Dr. Dostal's success lay in developing a culture medium. Another difficulty: animals not being susceptible to leprosy, it is necessary to experiment with humans...
...aged 67, Dr. Welch joined the medical reserve corps, was commissioned major. Continuing his research work, he discovered the Welch bacillus (named by others), the gas-producing organism causing "gas gangrene" which attacked many a wounded soldier. In recognition of this and other work he was commissioned brigadier general in the Officers Reserve Corps...
Researcher Beckman studied the cells, concluded that there must be some bacteria which would eat the cellulose walls, release the oil. In brewer's malt he found the bacterium Bacillus delbrueckia, which was apparently hungry enough to accomplish this...
Tuberculosis Sugars. Tuberculosis is a disease in which two living factors are concerned, the bacillus of tuberculosis and the body cells called monocytes. The bacillus lives parasitically within the monocyte. Each has its individual living chemistry. Together they have a third metabolism which causes the tubercles of tuberculosis to grow. This third chemistry varies with the strain of the bacillus and its animal host (man, cow, fowl, fish). But always typical compounds result-of fats with sugars, albumins with sugars. The fats and albumins in all types uf tuberculosis are very much alike. But the sugars differ greatly. Hence...
Continuing the researches of his great preceptors, Dr. Calmette with his associate C. Guérin, a veterinary surgeon, discovered that the descendants of the tuberculosis bacillus, bred for many generations in ox bile and glycerine, lost their virulency but could establish immunity in young animals against potent tuberculosis germs. In their experience the vaccine must be fed to an infant who has been exposed to the disease during its first ten days of life. Later it may be given hypodermically. It is powerless to cure, but has undoubtedly prevented tuberculosis...
