Since 1891 the Pasteur Institute had been extended to different countries, and currently there are 32 institutes in 29 countries in various parts of the world.[139]. His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. The chickens survived, and when he inoculated them with a virulent strain, they were immune to it. Tous les mots de ce site sont dans le dictionnaire officiel du jeu de scrabble (ODS).

Inoculation with smallpox (variolation) was known to result in a much less severe disease, and greatly reduced mortality, in comparison with the naturally acquired disease. [140] However, Catholic observers often said that Pasteur remained an ardent Christian throughout his whole life, and his son-in-law wrote, in a biography of him: Absolute faith in God and in Eternity, and a conviction that the power for good given to us in this world will be continued beyond it, were feelings which pervaded his whole life; the virtues of the gospel had ever been present to him.

He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. Pop culture [93] The treatment's success laid the foundations for the manufacture of many other vaccines. Many of his decrees, however, were rigid and authoritarian, leading to two serious student revolts. Then he closed the flask, and no organisms grew in it. [68] In another experiment, when he opened flasks containing boiled liquid, dust entered the flasks, causing organisms to grow in some of them. With both scientists claiming priority on the discovery, a dispute, extending to several areas, lasted throughout their lives. [7] After consulting with physicians, he decided to go ahead with the treatment. The number of flasks in which organisms grew was lower at higher altitudes, showing that air at high altitudes contained less dust and fewer organisms.
