LOUIS PASTEUR 

            Louis Pasteur is rightly considered as a great benefactor t mankind. His research work brought a revolution in the Medical Science. His research work can be undertaken as follows. 

ON SPONTANEOUS GENERATION

             The idea of spontaneous generation was common before Pasteur. The idea was that living thing could be produced from the dead matter. Many scientists were in favour of the idea but Pasteur rejected it he, on the basis of his experiments, proved conclusively that the germ could not be produced from dead matter. The French Academy offered a reward to him for the solution of this problem. His work on spontaneous generation was of great significance because it stimulate other scientists to study the habits of germs and much of our modern knowledge of these invisible sprang from Pasteurís work. 

ON BREWING AND FERMENTATION 

            In 1870, when France and Germany were at war with each other, he desired to be enrolled as a soldier but was not selected on physical grounds. His love for France prompted him to take up the study of brewing and fermentation. He discovered a method by which France might produce beer as good as that manufactured in Germany. Due to his work, it was thought that inflammation of the wounds might be a type of fermentation. He also explained how fermentation could be avoided. 

ON SILKWORM DISEASE 

            Growing silkworm was a thriving home industry in the South of France. The family of nearly every farmer was intact with this industry. The women used to take great interest in rearing and tending the worms because these were a major source of income to the family. In 1849, the moths were attacked by a disease that killed many of them. Much effort was made to cope with the situation but all in vain. Them Pasteur was asked to probe into the matter. So he closely studied the cause of the disease and finally concluded that germs were responsible for all that. He directed the worm-breeders to avoid over-crowding of the moths, uncleanness, over-heating and unhealthy conditions as these weakened the insects and made them more liable to the disease. His work saved France and the farmers began to prosper again. 

ON VACCINE PREPARATION AND THE TREATMENT OF HYDROPHOBIA (RABIES)  

            In 1877, Pasture started research on cattle disease ďAnthrax.Ē He proved that the disease was also due to germs so he developed a method to prevent the disease. He inoculated weak germs of the disease in the bodies of cattle. Due to this, antibodies were produced in their blood that could save the animals from the active germs of disease. This method was called vaccination. The first human disease to which Pasteur applied vaccination was hydrophobia (Rabies). This disease is caused by the bite of the mad dog. The symptoms of the disease are very drastic. These are spasm, restlessness, shudders at the least breath of air, an ardent thirst, great fear of water, etc. Pasteur prepared a vaccine for the disease. He took nervous tissue of am animal that had died of the disease and exposed it to dry air to weaken the germs.  

            In 1885, a boy who had been bitten by a mad dog was brought to Pasteur. He inoculated the weak germs in his body for ten days continuously. The boy was perfectly cured by this method. Then a large number of victims were also cured very successfully by vaccination. Afterwards, this method greatly helped the doctors in controlling over the diseases like, small-pox, diphtheria, cholera, typhoid fever and plague. 

            Pasteurís work on the diseases of both man and animals is so valuable that the entire world is deeply obliged to him. The French Government and the people of his country honored him during his life. The people from all parts of the world raised funds for building Pasteur institute in Paris. He paid yeoman services in the field of medicine and at last continuous hard work claimed his life. He died I 1895 and was buried in the institute that was built in his honor to pay him tributes.
