<h2>Koch's Postulates.</h2>

Explanation:

The next step should be isolate the microorganism from the mice and check if it is identical to the original microbe.

According to Koch's postulates, a microbe can be considered as a causative agent of a disease only after all the following are established:

  • The microorganism should be present in all the organism suffering from the disease.
  • The isolated microorganism should be grown in pure culture.
  • The organism grown in the culture should be reintroduced in the susceptible but healthy host.
  • Finally the microorganism must be re-isolated from the experimental host an cultured to see whether it is identical to the original specific microorganism.
