Answer:
Robert Hermann Koch was a physician, he gave 4 postulates on relationship between disease and their causative agent.
Step-by-step explanation
Kochs pastulates are as follows-
- Causative agents /microorganism always present in diseased individual, but should not present in healthy one.
- These causative microorganisms can be isolated and cultured.
