Koch's Postulates Can Be Used to Determine the Causes of Infectious

Question

Koch's postulates can be used to determine the causes of infectious diseases.

Accepted Answer

Koch's postulates are a set of guidelines used to determine the causative agent of an infectious disease. They involve isolating the pathogen from a diseased host, growing it in pure culture, introducing it into a healthy host to reproduce the disease, and then re-isolating the pathogen from the newly infected host. If all of these steps can be completed, it provides strong evidence that the identified pathogen is the cause of the disease.
