Five major categories of study in microbiology: bacteriology: bacteria, virology: viruses, mycology: fungi and yeast, parasitology: protozoa (amoeba) and meats (worms, immunology: immunity. Sizes of organisms: can vary from 6 feet worms to microscopic bacteria to macroscopic viruses (30nm-300nm: smallest - prion -infectious protein that has no cure (ex. mad cow disease) There is more bacteria than cells in the human body. Bacteria is needed because it: breaks down sugars (lipids), produces vitamins, produces substances that ght off other bacteria. Antibiotics that wipe out bacteria cause imbalance (ex. yeast infection) Immunocompromised is when there is an imbalance and creates a risk for infec- tion, because we require a strong immune system. Bacteria is named based on the genetic relat- edness (genus) and morphology. Genus comes before the species in the name and is often abbreviated ex.
