what are koch’s postulates used for
used as a set of rules to help scientists indentify the cause of a specific disease
rules of koch’s postulates
- The pathogen must always be found in the body of a sick organism
- The pathogen must be isolated
- When the cultured pathogens are introduced into a healthy host, they should cause the same disease that infected the original host.
- The injected pathogen must be isolated from the second host.
