USA HISTORY

Detailed explanation-1: -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. Using his germ theory of disease, he also developed vaccines for chicken 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: -Pasteur became a pioneer in the development of vaccinations, i.e., the introduction into the body of a mild (attenuated) form of a pathogen to produce immunity from the more harmful strain of the disease. He developed vaccinations for anthrax and fowl cholera, but his rabies vaccine was the most famous.

Detailed explanation-4: -The germ theory of disease states that contagious diseases are caused by “germs, ” or microorganisms, which are organisms that are too small to be seen without magnification. Microorganisms that cause disease are called pathogens. Human pathogens include bacteria and viruses, among other microscopic entities.

Detailed explanation-5: -In 1862, a French chemist named Louis Pasteur discovered that heat kills germs in liquids, preventing bacterial growth, food spoilage and foodborne illnesses. He used his discovery to invent methods that have been used for the last 150 years as a sanitary treatment for milk – which at the time was a prime source of TB.
