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

<h3>What is Gestation ?</h3>
The time during which an embryo, and eventually a fetus, develops inside viviparous animals is known as the gestational period. Although certain non-mammals also experience it, it is usual for mammals. When mammals are pregnant, they may have one or more gestations concurrently, as in the case of multiple births.
<h3>What is peripartum period ?</h3>
The time just prior to, during, and soon following childbirth.
Everyone agrees that the postpartum period starts when the baby is born. Although the end is less well defined, it is sometimes thought to occur six to eight weeks after delivery because by then the effects of pregnancy on many systems have essentially gone back to their pre-pregnancy states.
