Robert Koch was a German physician who identified the bacteria causing anthrax and tuberculosis. His methods established four criteria that must be met for a specific pathogen to be considered the cause of a disease. These four criteria are listed below. For each one, discuss whether Warren and Marshall fulfilled them and, if so, how. a. The pathogen should be found in the bodies of animals having the disease. b. The suspected pathogen should be obtained from the diseased animal and grown outside the body. c. The inoculation of that pathogen, grown in pure cultures, should produce the disease in an experimental animal. d. The same pathogen should be isolated from the experimental animal after the disease develops.
