LOUIS PASTEUR 1822-1895

French chemist and biologist, Louis Pasteur, is generally considered to be the son of ace ace in the history of medicine. Pasteur is presenting a lot of their contributions is important for the interests of science. But the most striking to him was his opinion on the theory of disease bacillus and the development of prevention techniques through injection.

Pasteur was born in the town of Dole in 1822, the eastern part of France. As a student in Paris he was to deepen knowledge. His genius is not visible when a student even one Grand Masters Pasteur considers "moderate" course in chemistry. Only after he obtained his doctorate in 1847, Pasteur proved false professors of speech. Study of the treaty acid (tartaric acid) on the glass lift to the degree that famous chemist when he was only twenty-six years.


Then he turned his attention to the investigation of the fermentation and proving that the process is exactly like a similar process occurs in other micro-organisms can memprodusir results are not desired in terms of beverage fermentation. This opinion was soon led other kegagasan that kind of micro-organisms can also produce things that are not expected and may take effect either on humans or animals.Pasteur was not the first to memasalahkan theory of disease bacillus. Similar hypothesis has been developed by Girolamo Fracastoro first, Friedrich Henle and many others. However, the most prominent Pasteurlah in terms of the germ theory of disease is demonstrated through a series of experiments and demonstrations are a major factor and convince people that his theory is true intellectuals.If the disease is caused by a bacillus, it seems plausible that preventing the entry of bacilli into the human body, the disease can be avoided. Pasteur therefore emphasize the importance of antiseptic methods for the doctors, and he had a major influence on Joseph Lister introduced antiseptic way into the field of surgery.Harmful bacteria that can enter the human body through food and drinks. Pasteur developed a technique (usually called pasteurization) to destroy micro-organisms in beverages. This technique, if practiced, can destroy the contaminated milk pests as the cause of the infection.When approaching the mid-fifties age, Pasteur turned his attention again to the investigation of animal disease bacillus, a type of serious infectious disease that attacks cattle and other animals, but not humans. Pasteur was able to show that the type of bacillus was the cause of illness. Other more important works is the development of techniques to produce patterns of livestock disease bacillus that has been attenuated. By injection into the animal's body, which was attenuated bacillus of this disease can cause a mild illness and did not result in fatal allowing the cattle acquire immunity to face the normal disease. Pasteur's public demonstration of the effectiveness of the technique immunize animals from livestock disease bacillus caused a stir. Soon realized that the general method can be used for the prevention of assorted social ills.Pasteur in his laboratoryPersonal discovery of Pasteur's most famous is the development of injection technique on humans to prevent the dreaded disease rabies. Other scientists, by mimicking the basic idea of ​​Pasteur, has since developed a vaccine to prevent other serious diseases such as typhoid and poliomyelitis.Pasteur, who likes a lot of excellent work, creating inventions are less important but still useful for the fragrance name. Is none other than his discovery - the discovery of meaning than others - which conclusively demonstrate that micro-organisms do not grow through breeding. Pasteur also discovered anaerobiosis phenomena, such as micro-organisms can survive anything in the absence of air or oxygen. Pasteur's work on silkworm diseases bring a high commercial value. Another discovery is the development of vaccines to prevent cholera outbreaks in poultry and poultry diseases that attack. Pasteur's last breath in 1895 near Paris.People often make comparisons between the Pasteur by Edward Jenner, English physicist who developed the vaccine for the prevention of smallpox. Although Jenner did 80 years before Pasteur, I consider the importance of Jenner is not for Pasteur, since pengebalannya system applies only to one type of disease course, while the Pasteur system can - and has been proven - effective to immunize against many diseases.As from mid-19th century, the needs of the world's population lives almost doubling hpat. Added requirement that absurdly fast and wide-reaching was more severe than what happened in the history of mankind. As a result, modern knowledge and the medical world we actually have to serve a second period of life. If the addition of this extra term can be attributed to solely the work of Pasteur business, I do not hesitate and falter again in the first place in the list order this book. However, Pasteur donation is so fundamental, so no question that Pasteur had a large stake in preventing the death rate at the end of this century
