What did Loui Pasteur discover?
He pioneered the study of molecular asymmetry; discovered that microorganisms cause fermentation and disease; originated the process of pasteurization; saved the beer, wine, and silk industries in France; and developed vaccines against anthrax and rabies.
What was Pasteur’s first discovery?
Pasteur’s first vaccine discovery was in 1879, with a disease called chicken cholera. After accidentally exposing chickens to the attenuated form of a culture, he demonstrated that they became resistant to the actual virus.
What did Louis Pasteur discovered in 1861?
In 1861, Pasteur published his germ theory which proved that bacteria caused diseases. This idea was taken up by Robert Koch in Germany, who began to isolate the specific bacteria that caused particular diseases, such as TB and cholera.

What vaccines did Pasteur invent?
During the mid- to late 19th century Pasteur demonstrated that microorganisms cause disease and discovered how to make vaccines from weakened, or attenuated, microbes. He developed the earliest vaccines against fowl cholera, anthrax, and rabies.
When did Louis Pasteur invent vaccines?
In 1881, he helped develop a vaccine for anthrax, which was used successfully in sheep, goats and cows. Then, in 1885, while studying rabies, Pasteur tested his first human vaccine. Pasteur produced the vaccine by attenuating the virus in rabbits and subsequently harvesting it from their spinal cords.
