American Educational JPT-T20 Harmful Bacteria Poster

For thousands of years, mankind has lived in fear of disease. Sometimes an unknown disease would appear suddenly, spread very rapidly and kill thousands of people. It was called an epidemic. No one knew what caused it or how to stop it. About 100 years ago, louis pasteur, a french scientist, discovered that some diseases were caused by tiny microscopic life forms that are not plants or animals. These tiny living things, called bacteria, would enter the body of an animal or plant and damage the cells. The science of bacteriology developed from this discovery. Since the days of Pasteur, scientists have discovered hundreds of different bacteria that cause different diseases. And they have found many ways to fight the harmful bacteria. The slides on this poster examine some of the harmful bacteria that cause disease in animals and plants. Grades 8-12. Ages 13-18.
