Viruses, Viroids & Prions (not really “organisms”) 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

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

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 Yogurt Sauerkraut Wine Beer
BACTERIAL PATHOGENS
OTHER BACTERIAL PATHOGENS Y. pestis N. meningitis B. burgdorferi
VIRAL PATHOGENS HIV Ebola Smallpox
EUKARYOTIC PATHOGENS Giardia Plasmodium Entamoeba
