Question

What are Koch’s postulates?

Answer 1

Koch’s postulates are a set of four criteria established by Robert Koch to prove that a specific microorganism causes a particular disease. They provide a logical basis to link a pathogen to a disease. The postulates are:

1. The organism must be regularly found in animals that have the disease and must be absent in healthy individuals.
2. The organism must be isolated and grown in pure culture on an artificial medium.
3. The pure culture of the pathogen must produce the disease when injected into a susceptible animal.
4. It should be possible to recover the injected pathogen from the experimentally infected animal.
