How Did Louis Pasteur Contribute To The Germ Theory Of Disease

Louis Pasteur, motivated by Edward Jenner’s discovery of the small pox vaccination, determined that other diseases could be cured by vaccinations as well, and he set out to systematically determine what caused the diseases, and how to develop the vaccines for them. While he was familiar with Edward Jenner’s smallpox vaccine, he did not really know how it worked, and so he started experimenting, doing various tests that may develop a cure for chicken cholera, rabies, anthrax, etc. There were multiple diseases that would sweep through areas and effect large numbers of the population. Pasteur is famous for several things, one of them being the discovery of micro-organisms. This discovery was a by-product of research that Pasteur had been asked

In 1854, Pasteur was appointed professor of chemistry and dean of the science faculty at the University of Lille (Ullmann, “Louis”). Whilst employed at Lille, he accepted a plea for studying solutions to problems associated to alcohol production at a local distillery, and with this catalyst, he began a series of studies on alcoholic fermentation. In 1857, while working with his research, Pasteur took a position with and was appointed manager and director of scientific studies at the cole Normale Supérieure (Ullmann, “Louis”). The observations he made

The intention of this paper is to examine the significant and enduring impact Louis Pasteur had on public health and wonderful advances in medicines and invention of vaccines. Louis Pasteur was a truly talented person who made many various discoveries in different areas of science. He invented Pasteurization, the process of treating milk free of damage causing microorganisms (Louis Pasteur, 2014). In 1843, Louis enrolled at the Ecole Normale Supe´rieure in Paris, where he focused in the origins of life. During the time he was professor in Strasbourg, France, he started investigating fermentation, which is a chemical process that breaks down organic substance. Pasteur became drawn to the field of transmittable diseases and the discovery of

Louis Pasteur was a French scientist in the 1800's. He is most famous for having invented the process of pasteurization that we still use today, but he developed many vaccines, including the one for rabies. He was highly motivated by his own curiosity and

In 1854 Louis Pasteur became a professor of chemistry at Lille. Shortly after, he became interested in fermentation. This was very helpful since alcohol making was a huge industry there. His interest in fermentation resulted in Louis developing many other interests. “In 1857 he jumped around from chemistry, biology then to medicine (Miller, 2002).” In 1860 he discovered pasteurization to kill bacteria in many food and beverages. This made a huge impact on the world. With pasteurization there would now be fewer illnesses due to people ingesting bacteria and parasites.

The food industry has been using this process all over the world. He also developed the first vaccine for rabies where he was testing on dogs but no humans yet. He finally administered a boy to get bit by a rabid dog and the boy lived to be an adult. Pasteur was awarded the Rumford Medal for the discovery of racemic acid. Then he was awarded the Montyon Prize for experimental physiology. He was awarded the Copley medal for fermentation and became a member of the Royal Netherlands Academy of Arts and

Who would have thought that soured beer would begin a study that would one day result in the discovery of several vaccines for deadly diseases? It all began when Bigo, a man who had manufactured beer from the sugar beet, went to see Pasteur. Louis Pasteur at the time was the Dean of the Faculty of Science at the University of Lille in France. Bigo asked Pasteur if he could discover why some of his beer became sour. Louis Pasteur used a microscope to study the vats of soured beer. He discovered that there were microorganisms in the beer. Because Louis Pasteur explored the possibility that these microorganisms were causing what is called putrefaction, a process of organic breakdown, he discovered many important facts. One of which was that microorganisms existed. He went on to explore the possibility that these microorganisms, or microbes, can be found airborne. Even when his peers scoffed at his ideas, Louis continued with his work. After discovering these microbes in wine, milk, and silkworms, Louis Pasteur believed that these microbes could affect human beings, that they could cause diseases.

b.) After culturing E. coli from his meat samples, what did he find regarding the pathogenicity and

Throughout history there have been many people intrigued by the idea of microbes. Many of those who have pursued this flitting notion may have been disappointed. Others have been wildly successful with methods they made up or borrowed. Sometimes the discoveries they make are purely based on chance or what you can call a lucky accident. The novel Microbe Hunters by Paul De Kruif documents thirteen scientists in total with twelve intricate chapters. In particular three scientists by the names Leeuwenhoek, Metchnikoff, and Paul Ehrlich have contributed greatly to the scientific community. They have presented great accomplishments which has benefited the study of immunology. This discipline is crucial to succor humanity in their fight against

The results suggest that pasteurization kills most pathogens in milk by brief exposure to relatively high temperature. This was demonstrated most beneficially with the 10-6 and 10-7 dilutions wherein the raw milk exhibited 284,000,000 cells/mL and 440,000,000 cells/mL respectively and the pasteurized milk had too few cell colony forming units to even count. Unpasteurized milk is not healthy for people to drink. For example, in a study performed in December of 2001, the bacteria Campylobacter jejuni, a microaerophilic bacteria commonly found in animal feces, was found in unpasteurized milk at an organic dairy farm in Wisconsin and caused 75 people, ages 2 to 63, to become ill.

In this experiment, each student was randomly assigned with a different species of gram- negative bacteria. The organism that I was assigned was Unknown #16. The identity of the gram-negative bacteria was determined to be Escherichia coli. The purpose of this report is to describe the various tests that helped develop a better understanding of the unknown microorganism in terms of the physiology, morphology, motility, and antimicrobic sensitivity it is characterized with. Indole production, hydrogen sulfide, and the colony morphology on the Eosin-methylene blue (EMB) plate, were the critical results that led to the conclusion that the organism was E. coli. In the indole production test, E. coli was one of two organisms,

Louis Pasteur was one of the brilliant scientists of his day. He was the one who discovered vaccines for Rabies, Anthrax, Cholera, Tuberculosis, and Smallpox. His most important discovery in medicine was the idea of injecting the disease into someone who already has the disease to build up immunity to it and help the body grow stronger. Besides the Rabies vaccine discovery, he is most known for discovering the idea called “the germ theory of disease,” which is the idea that specific germs cause diseases, and if they can determine the germ they can cure the disease by injecting it into the body. His motivation for these discoveries all started when a beer factory had fermented and the beer had gone sour. This caused the owner of the factory to question why and he brought in Louis Pasteur to help him figure out this anomaly. Louis figured out it was because of the microorganisms found in the beer that was causing it to sour. He began looking at different types of drinks as well like milk and

Another purpose of this experiment is to stress the importance of knowing the identity of a microorganism. Knowing the species of microorganism present in a sample provides a
