Question

Quizplus · Accepted Answer

Koch's postulates are a set of criteria used to establish that a particular microbe is the cause of a specific disease. These postulates were developed by Robert Koch, a German physician, and microbiologist in the late 1800s. The postulates state that the microbe must be found in all cases of the disease, isolated from the host and grown in pure culture, and then cause the disease when injected into a healthy host. Finally, the same microbe must be isolated from the newly infected host. Thus, Option B- a specific microbe is the cause of a specific disease is the correct answer.
