Louis Pasteur was a French chemist who created the first vaccines for both rabies and anthrax. Pasteur also invented the process that helps make milk and other liquids (and occasionally foods) safer to consume. That method is, of course, called pasteurization — and that word that is stamped on nearly every container of milk you can buy today.
Full Answer
How did Louis Pasteur cure rabies?
Success, not only in immunization, but in curing rabies after a victim had been bitten, encouraged Pasteur to try his method on a human being. And he got his chance in 1885, when the desperate case of a bitten boy was brought to him.
What did Louis Pasteur do with anthrax?
Pasteur then shifted his work focus to anthrax, which at the time was affecting cattle. In 1881, Pasteur performed a famous public experiment in which he injected one group of animals with an anthrax vaccine he had developed, and he did not vaccinate his second, control group.
How did Louis Pasteur’s experiment with chickens survive?
Amazingly, the chickens survived and did not become diseased; they were protected by a microbe attenuated over time. Glassware of the same type Louis Pasteur would have used to culture microorganisms. Realizing he had discovered a technique that could be extended to other diseases, Pasteur returned to his study of anthrax.

Scientist Louis Pasteur came up with the food preparation process known as pasteurization; he also developed vaccinations for anthrax and rabies. Scientist Louis Pasteur came up with the food preparation process known as pasteurization; he also developed vaccinations for anthrax and rabies.
What did Louis Pasteur do for rabies?
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.
Who developed a vaccine for rabies and anthrax?
Pasteur is also recognized for his work on vaccines; he was the first scientist to use live viruses in vaccinations. Pasteur's work in infectious diseases was momentous for the development of the rabies and anthrax vaccines specifically. Rabies and anthrax are animal-born diseases that cause serious symptoms in humans.

Indeed, almost 90 years after Jenner initiated immunization against smallpox, Pasteur developed another vaccine—the first vaccine against rabies. He had decided to attack the problem of rabies in 1882, the year of his acceptance into the Académie Française.
How did Pasteur discover a vaccine for chicken cholera?
In the summer of 1880, Pasteur found a vaccine by chance, after forgetting one of his cultures. With the help of a colleague Charles Chamberland, he showed that Chicken cholera germs from an old culture that had been around for some time lost their ability to transmit the disease. The inoculated chickens did not die.
Who invented cholera vaccine?

Why was Pasteur reluctant to accept his germ theory?
Nonetheless, the medical establishment was reluctant to accept his germ theory of disease, primarily because it originated from a chemist.
What was the cause of rabies?
Pasteur suspected that the agent that caused rabies was a microbe (the agent was later discovered to be a virus, a nonliving entity). It was too small to be seen under Pasteur’s microscope, and so experimentation with the disease demanded the development of entirely new methodologies.
How long after Pasteur's work did the sheep die?
Two weeks after these initial inoculations, both the vaccinated and control sheep were inoculated with a virulent strain of anthrax. Within a few days all the control sheep died, whereas all the vaccinated animals survived. This convinced many people that Pasteur’s work was indeed valid.
What was the significance of Pasteur's work?
The theoretical implications and practical importance of Pasteur’s work were immense. Pasteur once said, “There are no such things as pure and applied science; there are only science and the application of science.” Thus, once he established the theoretical basis of a given process, he investigated ways to further develop industrial applications. (As a result, he deposited a number of patents.)
Where did Pasteur's experiment take place?
The experiment took place in Pouilly-le-Fort, located on the southern outskirts of Paris. Pasteur immunized 70 farm animals, and the experiment was a complete success. The vaccination procedure involved two inoculations at intervals of 12 days with vaccines of different potencies.
Where is Louis Pasteur buried?

Influenced by Edward Jenner, Pasteur reasoned that if a vaccine could be found for smallpox, vaccines could be found for all diseases. By 1878, Pasteur had succeeded in culturing the causative virulent bacteria of chicken cholera and began inoculating chickens.
Why did Pasteur want to move into the more difficult area of human disease?
Pasteur then wanted to move into the more difficult area of human disease, in which ethical concerns weighed more heavily. He looked for a disease that afflicts both animals and humans so that most of his experiments could be done on animals, although here too he had strong reservations.
What was Pasteur's research campaign?
In his research campaign against disease Pasteur first worked on expanding what was known about anthrax, but his attention was quickly drawn to fowl cholera. This investigation led to his discovery of how to make vaccines by attenuating, or weakening, the microbe involved.

What did Dr Pasteur do to the spinal marrow?
Having ascertained that exposure to dried air diminished the virus, and consequently reduced its force, Dr Pasteur supplied himself with a series of bottles of dried air. In these bottles, he placed portions of inoculated spinal marrow at successive dates, the oldest being the least virulent and the latent the most so.
How long does it take for a Pasteur to inoculate?
For an operation, Dr Pasteur begins by inoculating his subject with the oldest tissue, and finishes by the injection of a piece of tissue whose bottling dates back only two days, and whose period of incubation would not exceed one week. The subject is then found to be absolutely proof against the disease.
