Rabies had presented a new obstacle for Pasteur in the development of a successful vaccine. Unlike chicken cholera and anthrax, both caused by bacterium, the microorganism causing the disease could not be specifically identified, meaning Pasteur would not be able to develop the vaccine in vitro (in the laboratory). Se hela listan på learninghypothesis.com It wasn’t until Louis Pasteur came along and proposed the germ theory of disease that the fields of modern microbiology and medicine were born. Pasteur proved that “bad air” wasn’t the source of disease, but rather that microorganisms were the cause of infectious diseases. Pasteur’s theory was unpopular and controversial, with French newspaper La Presse warning in 1860, “I am afraid the experiments you quote, M. Pasteur, will turn against you.

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 But beyond the experiments, Pasteur also devised, for a command performance at the Sorbonne before Princess Mathilde and other august personages, an equally remarkable staging of his scientific argument, which "made dramatic use of light and darkness, beams, shades, and shadows" and of "tangible ‘props’ such as … swan-necked flasks, bubbling chemicals, metallic tubes, etc." Geison I ett mästerligt framförande inför en nämnd av vetenskapsmän motbevisade Louis Pasteur framgångsrikt, punkt för punkt, teorin om uralstring.
