I’ll post outlined notes, usually the night before class… WHAT IS MICROBIOLOGY? The study of small organisms. Viruses, Viroids & Prions (not really “organisms”) Prokaryotes: Bacteria & Archaea Eukaryotic Microbes: Algae Fungi “Protozoa” LIFE IS DIVIDED INTO 3 DOMAINS Table 1.2 Table 1.3 How small is small? MICRON or MICROMETER - 1 millionth of a meter (10-6 meters) - symbol is µ NANOMETER - 1 billionth of a meter (10-9 meters) Bacteria are usually several micrometers in diameter. Fungi are about 10+ micrometers in diameter Fig. 1.13 THE HISTORY OF MICROBIOLOGY We will look at natural history and human history MICROBES ARE EVERYWHERE! • earliest life - 3.8 billion years old • represent more than half of the biomass (animals <15%) • almost every natural surface • important symbionts • vital to the ecosystem BACTERIAL SYMBIONTS MICROORGANISMS ARE VITAL TO NUTRIENT CYCLING MICROBIAL GENETICS MICROBIAL GENOMICS FOOD MICROBIOLOGY Bread Cheese Wine Yogurt Beer Sauerkraut BACTERIAL PATHOGENS OTHER BACTERIAL PATHOGENS Y. pestis N. meningitis B. burgdorferi VIRAL PATHOGENS HIV Ebola Smallpox EUKARYOTIC PATHOGENS Plasmodium Giardia Entamoeba Fig. 1.3.
