Who Was Louis Pasteur? Louis Pasteur discovered that microbes were responsible for souring alcohol and came up with the process of pasteurization, where bacteria are destroyed by heating beverages and then allowing them to cool.
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.

He was the first scientist to prove that cells can only form from pre-existing cells. He did this by creating an experiment that showed cells would only grow in broth if air was exposed.
What was the first challenge Pasteur faced while making the vaccine?
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).
What was the first germ discovered?
Two men are credited today with the discovery of microorganisms using primitive microscopes: Robert Hooke who described the fruiting structures of molds in 1665 and Antoni van Leeuwenhoek who is credited with the discovery of bacteria in 1676.
What was Louis Pasteur’s first research project?
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.
Which vaccine was discovered by Louis Pasteur?
The discovery of the chicken cholera vaccine by Louis Pasteur revolutionized work in infectious diseases and can be considered the birth of immunology.

How did Pasteur discovered the germ theory?
The more formal experiments on the relationship between germ and disease were conducted by Louis Pasteur between the years 1860 and 1864. He discovered the pathology of the puerperal fever and the pyogenic vibrio in the blood, and suggested using boric acid to kill these microorganisms before and after confinement.
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 diseases did Louis Pasteur create vaccines for?
In his ongoing quest for disease treatments he created the first vaccines for fowl cholera; anthrax, a major livestock disease that in recent times has been used against humans in germ warfare; and the dreaded rabies.
What did Louis Pasteur do in immunology and his discovery?
Louis Pasteur is traditionally considered as the progenitor of modern immunology because of his studies in the late nineteenth century that popularized the germ theory of disease, and that introduced the hope that all infectious diseases could be prevented by prophylactic vaccination, as well as also treated by .
What was Pasteur’s germ theory?
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.
How was the first vaccine created?
First vaccines Edward Jenner invented a method to protect against smallpox in 1796. The method involved taking material from a blister of someone infected with cowpox and inoculating it into another person’s skin; this was called arm-to-arm inoculation.
When did Louis Pasteur make his discovery?
Commercial Achievements He then invented a process where bacteria could be removed by boiling and then cooling liquid. He completed the first test on April 20, 1862. Today the process is known as pasteurization. Shifting focus, in 1865, Pasteur helped save the silk industry.
Who discovered vaccine for rabies?
Louis Pasteur developed the earliest effective vaccine against rabies that was first used to treat a human bite victim on 6 July 1885 [13].
When was the germ theory discovered?
1861
