Q

Koch’s Postulates

A
  1. Agent must be isolated and grown outside the host, 2. Suspected causative agent must be found in every case of the disease and be absent from healthy host, 3. When agent is introduced in healthy host, the host must get the disease, 4. Same agent must be re-isolated from diseased experimental host
