Louis Pasteur ForMemRS (/ ˈ l uː i p æ ˈ s t ɜːr /, French: [lwi pastœʁ] ⓘ; 27 December 1822 – 28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, the last of which was named after him.
[49] [56] But, Pasteur discovered Pébrine and flacherie were separate diseases. Pasteur claimed bacteria within the silkworms' intestinal track caused flacherie. He then used a microscope to sort which eggs were infected and which were not. This was an effective way of discarding the diseased eggs so these worms would not enter the population.
Amid anthrax vaccine's success, Pasteur introduced rabies vaccine (1885), the first human vaccine since Jenner's smallpox vaccine (1796). On 6 July 1885, the vaccine was tested on 9-year old Joseph Meister who had been bitten by a rabid dog but failed to develop rabies, and Pasteur was called a hero. [13] (Even without vaccination, not everyone ...

A representation by Robert Seymour of the cholera epidemic depicts the spread of the disease in the form of poisonous air.. The miasma theory was the predominant theory of disease transmission before the germ theory took hold towards the end of the 19th century; it is no longer accepted as a correct explanation for disease by the scientific community.
He realised that he had discovered a new form of virus and later coined the term "bacteriophage". [23] [24] Between 1918 and 1921 d'Herelle discovered different types of bacteriophages that could infect several other species of bacteria including Vibrio cholerae. [25]
The work of Pasteur and Koch did not accurately reflect the true diversity of the microbial world because of their exclusive focus on microorganisms having direct medical relevance. It was not until the work of Martinus Beijerinck and Sergei Winogradsky late in the nineteenth century that the true breadth of microbiology was revealed. [ 23 ]
