Microorganisms are all around us and as Louis Pasteur pointed out they play vital roles
in the ecology of life on Earth. Commercially, microorganisms have many roles such as those used in
the production of chemicals (antibiotics) and those that form an important part of the food industry.
Microorganisms are also major tools in basic research in the biological sciences. Medically, our
focus is on those microorganisms that cause disease. While we think of disease as being a human condition,
microorganisms also cause disease in other animals and plants. In this course, you will gain
first-hand knowledge using a variety of microorganisms, primarily bacteria.
