Study Notes
Koch's Postulates
- A set of guidelines for proving the causative agent of a disease
- First requirement: the pathogen must be found in all individuals displaying the symptoms of the disease in question
- Second requirement: the same pathogen must be able to be cultured from some individuals displaying the symptoms of the disease in question
