Koch’s Postulates
(4 items)

A
  1. The specific agent must be associated with every case of the disease.
  2. The agent must be isolated from a diseased host and grown in culture.
  3. When the culture-grown agent is introduced into a healthy susceptible host, the agent must cause the same disease.
  4. The same agent must again be isolated from the infected experimental host.
