source of energy to visualize specimens.
Electron Microscope
(ch.1) Kock's postulates state:
The microbe must be present in every animal with the disease.
The microbe can be isolated and grown in pure culture.
The cultured microorganism must cause the same disease in an inoculated (previously
healthy) animal.
The same microorganism must then be isolated from the diseased animal.
