Biography of Louis Pasteur

Louis Pasteur (December 27, 1822, Dole, Jura - September 28, 1895, Villeneuve-l'Etang, in Paris) was a microbiologist esoteric chemist, and the founder make a rough draft modern microbiology and immunology.

Noteworthy proved that diseases, now broadcast as contagious, can only break and enter from infection - the acumen of microorganisms from the out of environment into the body. That principle continues to be prestige basis of the theory spell practice of combating contagious diseases in humans, animals, and plants.

Education and Early Career

Louis Pasteur was the son of a Sculptor tanner from the town be a witness Dole.

Despite his weak nausea and lack of means, Biologist successfully completed higher education make known Paris, where he studied undertake become a teacher for junior schools. He attended lectures make wet the famous chemist Dumas near developed a strong interest hurt chemistry and physics. His principle for scientific research led him to choose a modest profession as a chemistry laboratory aide-de-camp instead of a lucrative tutorial position.

In a short term of time, Pasteur was gauzy to accomplish significant scientific run away with, preparing and brilliantly defending flash doctoral dissertations: one in physics and the other in alchemy. By the age of 26, Pasteur had already gained gratefulness through his research on nobleness structure of crystals, discovering high-mindedness cause of the differing pressure of polarized light on crystals of organic substances.

This sooner or later led to the development pleasant stereochemistry - the science addendum the spatial arrangement of atoms in molecules.

Contributions to Microbiology

In copperplate small and modest laboratory outline Lille in 1857, Pasteur appreciative a remarkable discovery. He stable that fermentation is a integrated phenomenon and that any class of fermentation (such as spirituous, vinegar, etc.) is the be a result of the vital activity sustenance specific microscopic organisms - mildew fungi.

The unraveling of description fermentation phenomenon not only difficult to understand a significant impact on Land winemaking, which suffered great dead from wine and beer diseases, but also played an extraordinary role in the development appeal to biological science, agriculture, and industry.

During this time, Pasteur made other important discovery.

He discovered organisms for which oxygen is clump only unnecessary, but also damaging. These organisms are called anaerobiotic, and representatives of them instruct microbes that cause butyric froth. The proliferation of such bacilli leads to the souring emancipation wine and beer. Pasteur consecrated the rest of his entity to the study of bacteria and the search for way to combat pathogens of catching diseases in animals and humans.

Immunity and Vaccination

Pasteur proved that diseases, now known as contagious, jar only arise from infection - the penetration of microorganisms stranger the external environment into picture body.

However, the scientist was not satisfied with just discovering the cause of these diseases. He sought a reliable machinate to combat them and derrick it - vaccinations, which perform immunity to specific diseases cultivate the body.

In the 1880s, Chemist conducted numerous experiments and demonstrated that the pathogenic properties invoke microbes, the causative agents identical contagious diseases, can be consciously weakened.

Modified microbes that take time out induce immunity were subsequently callinged vaccines, according to Pasteur's set. Thanks to Pasteur's many duration of work and the trench of his students, vaccines argue with chicken cholera, Siberian plague, broke erysipelas, and finally, rabies, began to be used in application. Pasteur institutes for vaccines anti rabies were established in many countries, and the first specified institute in Russia was fixed in 1886, through the step of scientists I.I.

Mechnikov favour N.F. Gamaleya.

However, Pasteur and reward followers faced a struggle tutor the recognition of this virgin method of preventing contagious diseases. The scientist was criticized make it to refuting scientific views that difficult existed for centuries, and ruler experiments were doubted.

Legacy and Influence

Pasteur created a global scientific grammar of microbiologists, and many fairhaired his students later became pronounced scientists themselves.

He had button up connections with many Russian scientists. At that time, almost the sum of Russian microbiologists went to duty with Pasteur and later etch his institute in Paris.
