The Genetics of

What is Microbiology?
Microbiology is the science that studies
Microorganisms, roughly, are those living things
that are too small to be seen with the naked eye
Microorganisms cannot be distinguished
phylogenetically from “Macroorganisms”, e.g.,
includes fungi as well as bacteria, etc. (that is,
they are not, as a whole, a closely related group

Microbiology is more a collection of techniques:

Microscopic observation of whole organisms, etc.
A microbiologist usually first isolates a specific
microorganism from a population and then
cultures it
