Part 2: Agents of Disease Notes

Robert Koch- 1884

Responsible for postulates (steps) to help figure out the cause of a disease:

    • The microorganism must be found in abundance in all organisms suffering from the disease, but should not be found in healthy organisms.
    • 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.
