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
