Document Summary
Introduction to microbiology: microbiology includes the study of other things that are microbes. It includes the study of bacteria, viruses, fungi, and eukaryotic parasites. What is in a microbe: microbes are microscopic. That is about the only definition for a microbe. You cannot see it, unless you use a microscope. The size range is 10^-7 m to 10^-3 m, but at least 1-5 microns is typical for a bacteria. The e. coli outbreak in germany was the first time that we isolated the bacteria from sick patients. Within 3-4 days, the entire genome of the bacteria was sequenced. We knew exactly what we were dealing with in terms of what the bacteria was doing and in terms of the cause of disease. We knew why it was a nasty bacteria. The speed at which we could analyze bacteria just in the past two years has absolutely revolutionized.
