Koch’s Postulates<br />
• The same pathogen must be<br />
present in every case <strong>of</strong> the<br />
disease<br />
• The pathogen must be isolated<br />
from the diseased host and<br />
grown in pure culture<br />
• The pathogen from the pure<br />
culture must cause the disease<br />
when it is inoculated into a<br />
healthy, susceptible animal<br />
• The pathogen must be isolated<br />
from the inoculated animal and<br />
must be shown to be the<br />
original organism<br />
