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
