Answer:

4. The suspected causative agent must be isolated from the diseased host and grown in pure culture

Explanation:

Robert Koch (1843-1910) was one of the most important bacteriologists of all time. Famous for discovering the tuberculosis bacillus (precisely on March 24, such as today, in 1882), he also discovered the cholera bacillus and is considered the founder of bacteriology. He worked on the isolation of infectious agents and reinfections from pure cultures, experiences from which he established the "Koch Postulates".

These postulates have been taken as a reference that describes the etiology of all the causative agents of an infectious disease, although they were originally used to describe only the tuberculosis bacillus. They are the following:

1- The agent must be present in each case of the disease and absent in the healthy.

2- The agent should not appear in other diseases.

3- The agent must be isolated in a pure culture from the lesions of the disease.

4- The agent has to cause the disease in an animal that can be inoculated
