Koch's Postulates (Procedures): Step 1. ASSOCIATION: The suspected pathogen must be consistently associated with the diseased plant (or animal). Step 2. ISOLATION: The pathogen must be isolated and grown in pure culture and its characteristics described. Step 3. INOCULATION: The pathogen from pure culture is inoculated into a healthy plant of the same species or variety and it must produce the same symptoms and signs. Step 4. RE-ISOLATION: The pathogen is re-isolated from the inoculated plant and its characteristics must be the same as the organism initially isolated in step 2. Ask a question- Is this a pathogen Do Research- find the suspected pathogen and isolate it and grow a pure culture Construct a Hypothesis- Test- Inject suspected pathogen into healthy organisms Analyze and Conclude- If suspected pathogen has produced same signs and symptoms in multiple tests on same organisms then it is indeed a pathogen Communicate Results
A harmless pathogen can be injected into your body so that the bodies defence system will learn to recognise the antigens (harmful protein located on surface of pathogen) and to fight it easily the next time having remembered the antibodies it had to produce. and sorry if this is a little confusing.
