Final answer:
Koch's postulates would be utilized in the development of a new antibiotic, formulation of a new vaccine, determination of the cause of cancer, and determination of the cause of a patient's illness.
Step-by-step explanation:
Koch's postulates would be utilized in the following situations:
- Development of a new antibiotic in a pharmaceutical lab
- Formulation of a vaccine against a new pathogen in a genetic engineering lab
- Determination of the cause of cancer in a patient
- Determination of the cause of a patient's illness in a hospital microbiology lab
Koch's postulates are a set of criteria that must be met in order to establish a causal relationship between a microorganism and a disease. These postulates involve isolating the microorganism, culturing it in pure culture, infecting a healthy organism with the cultured microorganism, and re-isolating the same microorganism from the newly infected organism.
