Which of the following statements are part of Koch’s Postulates? Check all that apply.

Koch’s Postulates include isolating the suspected microorganism from a diseased organism and growing it in a pure culture. The microorganism should then cause disease in a healthy, susceptible host, and the same microorganism should be recovered again. Choice B, “The microorganism can be isolated and grown in a pure culture,” is part of the postulates; the postulates do not use a half-of-cases or 80% threshold, and the re-isolated microorganism should not be a different species.
