Reading Summary - Chapter 1
The Microbial World and You

© 2013 Dr. Dennis Jackson


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.
