In his work with silkworms, Pasteur developed practices that are still used today for preventing disease in silkworm eggs. Using his germ theory of disease, he also developed vaccines for chicken cholera, anthrax, and rabies. This, however, was debunked by Louis Pasteur whose research on sterilization clearly indicated that this was not the case.
Most of the animalcules are now referred to as unicellular organisms, although he observed multicellular organisms in pond water. In , Dmitri Ivanovsky used one of these filters to show that sap from a diseased tobacco plant remained infectious to healthy tobacco plants despite having been filtered.
Germ is a deceptively simple word that came to us from Latin germen, meaning a sprout, bud, or offshoot. In all of its meanings, the term germ retains the idea of developing into something more mature.
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. Pasteur reasoned the factor that made the bacteria less deadly was exposure to oxygen. The discovery of the chicken cholera vaccine by Louis Pasteur revolutionized work in infectious diseases and can be considered the birth of immunology.
It was also the first disease for which a vaccine was produced. Although at least six people had used the same principles years earlier, the smallpox vaccine was invented in by English physician Edward Jenner…. Ten of these vaccines have been recommended for use only in selected populations at high risk because of area of residence, age, medical condition, or risk behaviors.
A vaccine stimulates your immune system to produce antibodies, exactly like it would if you were exposed to the disease. Before Louis Pasteur, it was believed that miasma bad air caused disease and that spontaneous generation is the process in which decaying matter creates living organisms such as maggots and another insect to be the way in which that decaying matter would end up with living organisms on it. In Louis Pasteur discovered microbes after performing experiments for the alcohol industry to find out why the wines and beers were going bad he could not have done this without the new technologies of the time such as the powerful electron microscopes.
After Pasteur found out about this he set about to use this to find a vaccine for chicken cholera, in my opinion, this was only because Pasteur was French and German and at this time there was the Franco-Prussian war was upon them.
After experimentation with chickens, Pasteur and his lab partner found out that if you inject a weakened sample of chicken cholera in the chickens they become immune to the infection after this Pasteur also discovered a vaccine for tuberculosis. After years of work and experimenting with over chemicals none worked until his results were checked again and appeared to have 1 working chemical. He then invented a process where bacteria could be removed by boiling and then cooling liquid.
He completed the first test on April 20, Today the process is known as pasteurization. Shifting focus, in , Pasteur helped save the silk industry. He proved that microbes were attacking healthy silkworm eggs, causing an unknown disease and that the disease would be eliminated if the microbes were eliminated.
He eventually developed a method to prevent their contamination and it was soon used by silk producers throughout the world. Pasteur's first vaccine discovery was in , with a disease called chicken cholera.
After accidentally exposing chickens to the attenuated form of a culture, he demonstrated that they became resistant to the actual virus. Pasteur went on to extend his germ theory to develop causes and vaccinations for diseases such as anthrax, cholera, TB and smallpox. On July 6, , Pasteur vaccinated Joseph Meister, a 9-year-old boy who had been bitten by a rabid dog. The success of Pasteur's vaccine brought him immediate fame. This began an international fundraising campaign to build the Pasteur Institute in Paris, which was inaugurated on November 14, Pasteur had been partially paralyzed since , due to a severe brain stroke, but he was able to continue his research.
He celebrated his 70th birthday at the Sorbonne, which was attended by several prominent scientists, including British surgeon Joseph Lister. At that time, his paralysis worsened, and he died on September 28, Pasteur's remains were transferred to a Neo-Byzantine crypt at the Pasteur Institute in We strive for accuracy and fairness.
