Taxonomy & Classification

Question 1

How do we classify microorganisms?

Answer 1

We use the science of taxonomy.

Question 2

How do we name them?

Answer 2

We use the system called Natural Classification developed by Swedish botanist

Carolus Linnaeus

Question 3

Why is taxonomy important

Answer 3

If we cannot identify and classify microorganisms we cannot control them.

e.g. Quarantine or in diagnosis for administering treatments.

•

So we can ascribe characteristics learned from one microbe to others that are

related.

Disclaimer:

•

The science of Taxonomy is always changing.

•

With better techniques and more information – how we

classify microorganisms CAN and DOES change.
