Koch's postulates are: The microorganism must be found in abundance in all organisms suffering from the disease, but should not be found in healthy animals. The microorganism must be isolated from a diseased organism and grown in pure culture The cultured microorganism should cause disease when introduced into a healthy organism. The microorganism must be reisolated from the inoculated, diseased experimental host and identified as being identical to the original specific causative agent.
