The relationship between insects and disease
essay on Biography Of Louis Pasteur: Louis Pasteur (1822–1895) was a French biologist and chemist whose discoveries in the modern age of modern scientists led to the causes and prevention of disease.
Inventor of Pasteurization : Louis Pasteur
The early years
Louis Pasteur was born on December 27, 1822 to a Catholic family in Dole, France. He was the third child of Jean-Joseph Pasteur and Jeanne-Etienne Requi. He attended primary school at the age of nine and did not show any particular interest in science at that time
essay on Biography Of Louis Pasteur
During his career, Pasteur conducted research that launched modern science and scientific research. Because of his invention, people can now live longer and healthier lives
His early work with French winemakers, in which he developed a way to sterilize and kill pesticides, meant that all kinds of liquids could be safely brought to market—wine, milk, and beer. He was also granted US Patent 135,245 for “Improvements in Brewing Beer and Ale Pasteurization”.
Additional achievements included the discovery of a cure for a specific disease that affected silkworms, which was an overwhelming boon to the textile industry. He also discovered treatments for chicken cholera, anthrax, and rabies.
Inventions in Chemistry and Microbiology
In addition to his work on molecular chirality, for which he was awarded the Rumford Medal in 1856, Louis Pasteur published two articles on aspartic and malic acid (1851 and 1852). For this work, he was made in 1853, being Knight Commander of the Imperial Order of the Legion of Honor and will be followed by the Paris Pharmaceutical Society Prize.
His memoirs on fermentation called “Dairy”, published in 1857, when he was appointed administrator of the ENS, revealed the microbial origins of fermentation. This can logically be seen as the starting point of a new discipline: microbiology.
Indeed, Pasteur Establishes that certain fermentations (lactic acid, butyric acid) are the work of living organisms, since the absence of substances that play the role of fermentation was not taken into account. He will also discover that the acidity of wine is due to certain bacteria, and will also direct his research to beer. .These discoveries, like most others, would generate much controversy.
Louis Pasteur continues his research and believes that the theory of spontaneous generation, going back to Aristotle, cannot be applied to the phenomenon of fermentation. According to him, the microorganisms involved in the fermentation process were the real cause, which he would prove at the Sorbonne in 1864. Then he will develop the so-called “pasteurization” method… This is a process of canning food by heating it to a temperature of 66 to 88 ° C, followed by rapid cooling.
Infectious diseases and vaccination
From 1865, for four years, he traveled to growers in Ales, where pebrine – a disease of silkworms – seemed more and more alarming because it put the industry at risk. It will succeed in ending the epidemic, having developed a way to stop it from spreading.
On the other hand, it may not cure another disease: Flesharia.Subsequently, he will be interested in chicken cholera, anthrax or red mullet, and for the future of critical research. By inoculating chickens with weakened cholera bacteria, he realizes that they do not contract the disease and become more resistant.
The finding would be confirmed by similar manipulations of flocks of sheep for anthrax.Louis Pasteur saw under the microscope a bacterium – staphylococcus, which he isolated from a boil in 1880. Established association with symptoms of inflammation and suppuration.Then the man picked up rabies and explained in 1881 that he had succeeded in making sheep immune by injecting the saliva of a rabid dog with its blood.
Louis Pasteur disease is sure to concern the nervous system, and it is possible to acquire a weakened form of the virus with great difficulty. After successful experiments on several animals in 1885, it was a stroke of luck… Although he was afraid to use this method on humans, he finally took the risk to cure a child bitten by a dog and saved him.This hundredth breakthrough was approved in 1888 by the Institute Pasteur, an institute dedicated to the research of rabies and other diseases.
In 1857, Pasteur moved to Paris, where he held a series of professorships before opening the Pasteur Institute in 1888. The aim of the institute was the treatment of rabies and the study of poisonous and infectious diseases.The institute pioneered studies in microbiology, and in 1889 studied the first class in the new discipline.
Beginning in 1891, Pasteur began opening other institutes across Europe to further his ideas. Today there are 32 Pasteur institutes or hospitals in 29 countries around the world.
During the lifetime of Louis Pasteur, it was not easy to convince others of his ideas, controversial in his ideas, but still considered quite correct today. Pasteur fought to convince his audience that germs existed and that they were the cause of disease, “bad air”, not a prevailing theory up to that point.
Furthermore, he emphasized that germs can be spread through human contact and medical instruments, and that it is imperative to kill germs through disinfection and sterilization to stop the spread of disease.In addition, Pasteur pursued the study of virology. His work with rabies led him to realize that weak forms could be used as “immunization” against strong forms.
Chances only favor the prepared.”
During his researches in chemistry, he worked as an assistant to a famous scientist named Ballard. The act of fermenting and producing bacteria in some foods was his main subject. He made the important discovery that some foods could be made using the process of fermentation.
The discovery of the pasteurization method of sterilizing milk was important. Apart from this, he also invented the rabies vaccine. He died on 28 September 1895.”Science knows a country, as knowledge is for humanity, and the flame that lights the world.
Some historians disagree with the accepted knowledge of Pasteur’s discovery. On the centenary of the biologist’s death in 1995, a historian specializing in science, Gerald L. Gazon published a book analyzing Pasteur’s private notebooks,
which had been made public only a decade earlier. In “The Private Science of Louis Pasteur”, Gazon asserted that Pasteur gave misleading accounts of many of his important discoveries.Still other critics labeled it an out and out fraud.Although Pasteur’s work saved millions of lives, there is no denying it.
