Louis Pasteur - Vaccines, Microbiology, Bacteriology: In the early 1870s Pasteur had already acquired considerable renown and respect in France, and in 1873 he was elected as an associate member of the Académie de Médecine. Nonetheless, the medical establishment was reluctant to accept his germ theory of disease, primarily because it originated from a chemist. However, during the next decade ...
Still, it has been little more than a century and a half since Robert Koch made the discoveries that led Louis Pasteur to describe how small organisms called germs could invade the body and cause disease.
Although the work of Semmelweis and Snow successfully showed the role of sanitation in preventing infectious disease, the cause of disease was not fully understood. The subsequent work of Louis Pasteur, Robert Koch, and Joseph Lister would further substantiate the germ theory of disease.
Figure 3.4 (a) French scientist Louis Pasteur, who definitively refuted the long-disputed theory of spontaneous generation. (b) The unique swan-neck feature of the flasks used in Pasteur’s experiment allowed air to enter the flask but prevented the entry of bacterial and fungal spores.
Louis Pasteur’s Work with Diseases. Pasteur extended the germ theory of fermentation to human and animal diseases, and speculated that diseases are also the result of germs growing in the body. With this in mind, he investigated several diseases including pébrine and flacherie in silkworms, chicken cholera, anthrax in sheep, and rabies in ...
However, Pasteur made several other very important contributions to science that you should know about. Molecular asymmetry. In studying crystals of sodium ammonium tartrate, Pasteur found that although they had the same chemical composition, they did not necessarily have the same structure. He noted that the molecules occurred in two mirror ...
Medicine in 18th- and 19th-century Britain saw great change, especially following the publication of Louis Pasteur’s germ theory. This led to significant changes in surgery and better prevention ...
