What is microbiology?
Rod shaped bacteria
Microbiology is the study of microorganisms - bacteria, protozoal parasites, viruses and fungi. These organisms can only be seen under the microscope but despite their size these micro-organisms, or microbes for short, have a massive impact on our lives. It has been estimated that there are 5X1030 or 5 million trillion, trillion, microbial cells on Earth. The total amount of carbon in these cells is equivalent to that of all of the plants on the planet! They collectively constitute the largest mass of living material on earth and play a critical role in shaping the environment that we live in. Humans, plants and animals are intimately tied to the activities of microbes which recycle key nutrients and degrade organic matter. Some microbes, however, are pathogenic.
