The first step for directly linking a microbe to a specific disease according to Koch's postulates is to
A.isolate microbes from the blood of healthy animals.
B. culture the blood or other body fluid from a diseased animal using nutrient medium.
C. inject a sample of blood or other body fluid from a diseased animal into a healthy animal.

Which of the following compounds represents a peptidoglycan specific antibiotic ?
A. tetracycline
B. chloramphenicol
C. penicillin
D. aspirin
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
