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 ...
Though Pasteur was fearful, he was faced with a choice when a child was brought to Hôpital des Enfants-malades with multiple bites from a rabid dog. The child's doctor Joseph Grancher asked Pasteur to treat the boy even though Pasteur was unsure of the vaccine's effect on a human. Dr. Grancher reminded Pasteur that he would die regardless. [49]
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.

Louis Pasteur in his laboratory, painting by A. Edelfeldt in 1885. When animals were infected with the bacteria, anthrax occurred, proving that the bacteria was the cause of the disease. [107] Many cattle were dying of anthrax in "cursed fields". [70] Pasteur was told that sheep that died from anthrax were buried in the field.
It was the first virus to be discovered, and the first to be crystallised and its structure shown in detail. The first X-ray diffraction pictures of the crystallised virus were obtained by Bernal and Fankuchen in 1941. On the basis of her pictures, Rosalind Franklin discovered the full structure of the virus in 1955. [35]
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 ]
Bacteria could be seen under microscope, and cultured on agar plates. In 1890, Louis Pasteur declared "tout virus est un microbe": "all infectious diseases are caused by microbes". In 1892, Dmitri Ivanovsky discovered that the cause of tobacco mosaic disease could pass through Chamberland's porcelain filter. Infected sap, passed through the ...
