I’ll post outlined notes, usually the night before class…

4. 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”

5. LIFE IS DIVIDED INTO 3 DOMAINS

6. Table 1.2

7. Table 1.3

8. 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

10. THE HISTORY OF MICROBIOLOGY
We will look at natural history and human history

11. MICROBES ARE EVERYWHERE!
• earliest life billion years old
• represent more than half of the biomass
(animals <15%)
• almost every natural surface
• important symbionts
• vital to the ecosystem
