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 ...
After doing so, he injected animals with the bacteria and found M. tuberculosis rods in their tissues. But he also discovered that a non-infected animal that was housed with an infected animal would also die of tuberculosis. The bacteria was also found in their tissue. Koch then stated that tuberculosis could be spread from human to human. [70]
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 ] (

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.
In Pasteur's day, and for many years after his death, the word "virus" was used to describe any cause of infectious disease. Many bacteriologists soon discovered the cause of numerous infections. However, some infections remained, many of them horrendous, for which no bacterial cause could be found.
Scientists in Brazil found microplastics in the brain tissue of cadavers, according to a new study published Monday in the journal JAMA Network Open.. Mounting research over the last few years has ...
