Who Would Have Thought That Soured Beer

Louis Pasteur was a very curious man that is recognized as the founder of the term germ and many advances in the medical field. Pasteur wanted to prove a theory he had about immunity in which he asked questions about the potential success or failure and the reason why some people or animals didn't get as sick as others. These questions lead to his theory about early exposure to a weakened bacteria and the strength of the immune system within an organism. He decided to perform an experiment on sheep in which he gave a “vaccine” to a certain number of them and didn't give it to some others. Later he went back and exposed all off them to a stronger bacteria which killed the ones that weren't given the vaccinations. This discovery is the basis

Louis Pasteur put forward the germ theory in 1861 this consisted of micro-organisms cause decaying matter. Pasteur never showed the link between bacteria and human disease. Robert Koch further developed Pasteur’s theory. Koch succeeded in what Pasteur did by linking one microbe with a disease. The first disease Koch worked on was anthrax, which Davaine had also worked on. Davaine found that in you inject a health animal with a small dose of the disease they won’t contract the disease. But Koch was able to further his research on the disease and its life cycle. It was the work of Pasture and Koch that opened the door for other researchers to identification of disease-causing and lifesaving treatments.

The doctors that came up with the treatments for this disease were French and American. The American and French doctors were similar in many ways. They both treated yellow fever and they were both curing in the same city ,Philadelphia.

In 1770s, British doctor Edward Jenner found the cowpox, which helped people to against small poxvirus. In 1820s, the British invented the prevention of pox vaccines,

He was inspired by the tales of milkmaids who already suffered cowpox and did not catch a severe case because their immunity was built to prevent further infection from cowpox. The first experiment was based off of this tale. He injected pus from a milkmaid’s cowpox pustule into a healthy boy and later discovered that when he injected the boy with smallpox a few weeks later, the boy did not become deathly ill. The same experiment was tested on a milkmaid who had not contracted either cowpox or smallpox, and the results were identical to the boy’s, which confirmed the effective use of the vaccine (Dr. Edward Jenner, "An

The French and American doctors both were highly trained. Both cared about the patients. They wanted them to stay healthy. Both French and American doctors cames from different places, but they came for the same for the same reason and that was to cure people with yellow fever.

Scientist, Louis Pasteur, is known as “the white knight of science.”[1] His discoveries have impacted the world for good. Though most may not know who he is, his influence touches the lives of people all over the world. Some of Pasteur’s most significant contributions to the world are his discoveries surrounding germs. Pasteur uncovered how dangerous germs are and that doctors can stop the spread of germs by properly sanitizing themselves and their instruments.[2] He was the pioneer of immunizations as he discovered that “weak forms of disease could be used … against stronger forms”[3] of viruses. He was also responsible for “introducing the medical world to the concept of viruses.”[4]

Edward Jenner created the first vaccines in 1798. He developed a vaccine to protect against small pox. Due to Edward Jenner’s vaccination, other scientists began to create vaccines for other disease like Typhoid, Rabies, and the Plague. With vaccines production climbing, the

Louis Pasteur began his discoveries in the late 1800’s by discovering asymmetry as a sign of life. While studying fermentation processes, he discovered that yeast itself was a living process. Pasteur then found how to observe microorganisms, by isolating and providing a growth medium, impacting the future of biotechnology. His discoveries provided the future of wine, beer, vinegar and dairy industries. Pasteur wondered why milk and meat were getting sour or decaying, so he began to experiment. Anton van Leeuwenhoek gave Pasteur the curiosity to see if molecules just spontaneously appear. By exposing grapes to the air resulting in fermentation, Pasteur discovered that germs come from the outside world. This brought the discovery of germs, which

Louis Pasteur discovered how to vaccinate against infectious disease, but it was a long process before he got to that point. He first studied the process of fermentation, which is when sugars are turned into alcohol. When a vinegar manufacturer wanted to know why his vinegar was spoiling, Pasteur found that it was because yeast (a microscopic fungus) had come in contact with the juice. He found that by heating the beet juice to a controlled temperature, the yeast was killed, and the fermentation process was stopped. Today this process is known as pasteurization, and it is applied to all kinds of food such as milk and cheese. He took what he had learned and eventually isolated the organism that was causing silk worm eggs to be infected with disease and developed a method to prevent the eggs from becoming

Edward Jenner, born in 1749, was a doctor and also the pioneer of the vaccination for smallpox. In 1796 his famous experiment was carried out, when a milkmaid approached Jenner and enquired about a rash on her hand. He then diagnosed the milkmaid with cowpox and not smallpox. Jenner took this opportunity to test properties of cowpox on an individual who had not yet encountered either disease. He inserted pus taken from a cowpox pustule from the milkmaid into an open cut that was on James Phipps arm. After a few days, James Phipps had become ill with cowpox, but recovered several days after. Due to this is Jenner knew that not only could cowpox be passed from cow to person, but also from person to person. His theory was being tested that milkmaids who had suffered

Pasteur had already done work six years earlier with the disease chicken cholera, a disease that was to blame for the elimination of chicken flock in France. Through this one vaccine he produced for a single species of bird, he was able to discover the phenomena of virulence, or the harmful quality of a microorganism that causes the

Louis Pasteur, one of the most influential chemists in the world, developed a process that saved many lives and continues to do so on a global scale. In the mid-18th century, when scientists were questioning the role of microorganisms, Pasteur investigated and supported the germ theory, through his extensive laboratory studies. He made many contributions to the various fields of science. Louis Pasteur is the most influential chemist in the history of the world specifically because of his discovery of the pasteurization process, which kills germs, helping to prevent illness.

This method, which is now known as inoculation, was observed by doctors in England, around the 18th century and was therefore adopted in England and France as new knowledge to prevent the spread of the disease to some of the population was discovered. While these methods were found to cause some serious and often life-threatening smallpox infection, in 1796, an English doctor, named Edward Jenner established a much safer approach to immunising people against smallpox. He inoculated healthy people with fluid containing the cowpox virus which was a much less dangerous disease and he found that by doing so, they were more likely to be protected against the infection. He also found that this immunity could be passed from one person to another genetically. This process is what we know call vaccinations, where a killed microbe is injected into the body to stimulate the immune system. This example demonstrates how we can use science and observations of the world to produce knowledge in order to solve problems.
