WORLD HISTORY

Detailed explanation-1: -During the mid-to late 19th century Pasteur demonstrated that microorganisms cause disease and discovered how to make vaccines from weakened, or attenuated, microbes. He developed the earliest vaccines against fowl cholera, anthrax, and rabies.

Detailed explanation-2: -During his experiments in the 1860s, French chemist Louis Pasteur developed modern germ theory. He proved that food spoiled because of contamination by invisible bacteria, not because of spontaneous generation. Pasteur stipulated that bacteria caused infection and disease.

Detailed explanation-3: -Louis Pasteur (December 27, 1822-September 28, 1895) was a French chemist and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization.

Detailed explanation-4: -The germ theory of disease was devised by Louis Pasteur. He also performed various experiments to demonstrate the relationship between microorganisms and diseases.

Detailed explanation-5: -Louis Pasteur is best known for inventing the process that bears his name, pasteurization. Pasteurization kills microbes and prevents spoilage in beer, milk, and other goods. In his work with silkworms, Pasteur developed practices that are still used today for preventing disease in silkworm eggs.
