Koch's postulates state: The suspected causative agent must be absent from all healthy organisms but present all diseased organisms. The causative agent must be isolated from the diseased organism and grown in pure culture. The cultured agent must cause the same disease when inoculated into a healthy, susceptible organism. The causative agent must then be reisolated from the inoculated, diseased organism. Choose any TWO of Koch's postulates and explain why it's faulty, given our current understanding of microbiology.

The first postulate states that the suspected causative agent must be absent from all healthy organisms but present in all diseased organisms. This postulate is faulty because there are many instances where healthy organisms can carry a pathogen without showing Show more…

These are the major tenets of Koch's postulates: a. The pathogen must be isolated from the inoculated animal and must be shown to be the original organism. b. The pathogen must be isolated from the diseased host and grown in pure culture. c. The same pathogen must be present in every case of the disease. d. The pathogen from the pure culture must cause the disease when injected into a healthy susceptible laboratory animal. What is the exact order/sequence of these components of Koch's postulates? a-b-c-d c-c-d-a c-b-a-d d-c-b-a
