Students have asked these similar questions
the following are the steps, listed in random order, for utilizing koch's postulates. what should be the second step out of the four listed?
a. a microorganism is found to be present in every case of a disease.
b. the same microbe discovered previously is isolated from the purposely infected host
c. the pathogen is isolated and grown in pure culture
d. the same disease results after isolated organism is inoculated into healthy host
The following are the limitations of Koch's postulates EXCEPT:
A. some pathogens cannot grow on artificial media and therefore cannot be identified as the causative agent
of the disease
B. some diseases involve multiple pathogens which produce similar symptoms making it difficult to pinpoint
the causative agent
C. some diseases are host-specific and re-inoculation may pose ethical concerns
D. some microorganisms are present in the body fluids of the infected animal which make them difficult to be
cultured
Which of the following compounds represents a peptidoglycan specific antibiotic ?
A. tetracycline
B. chloramphenicol
C. penicillin
D. aspirin

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. Discuss in detail how Warren and Marshall fulfilled each criteria. 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. I d. The same pathogen should be isolated from the experimental animal after the disease develops. 31arrow_forward
