WHAT IS MICROBIOLOGY?

The study of small organisms.

Prokaryotes:

Bacteria & Archaea

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

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 !m

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!

• represent more than half of the biomass

(animals <15%)

• almost every natural surface

• important symbionts

• vital to the ecosystem

• earliest life - 3.8 billion years old

BACTERIAL SYMBIONTS MICROORGANISMS ARE VITAL TO NUTRIENT

CYCLING

MICROBIAL GENETICS

and Genomics

FOOD MICROBIOLOGY

Bread Cheese Yogurt Sauerkraut

Wine Beer

BACTERIAL PATHOGENS

e.g. Y. pestis, N. meningitis, B. burgdorferi

VIRAL PATHOGENS

e.g. Ebola, West Nile, Smallpox, HIV

EUKARYOTIC PATHOGENS

e.g. Plasmodium, Entamoeba, Giardia
