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

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!

• 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
