- A. A specific organism can always be found associated with a disease
- B. The organism cannot be isolated and grown in a pure culture in the laboratory
- C. The pure culture will produce the disease when innoculated into a suscepticle animal
- D. It is possible to recover the organisms in pure culture from an experimentally infected animal
Explanation
The germ theory of disease states that some diseases are caused by microorganisms. Robert Koch formulated four postulates, which are the main pillars of the germ theory of disease. These are used to find out whether the organism found in disease lesions is the causal agent of the disease or not.1. A specific organism can always be found in association with a given disease.2. The organism can be isolated and grown in pure culture in the laboratory.3. The pure culture will produce the disease when inoculated into susceptible animals.4. It is possible to recover the organism in pure culture from an experimentally infected animal
