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
A compound synthesized by bacteria or fungi that destroys or inhibitsthe growth of other microbes is a(n)a. synthetic drug
b. antibiotic
c. antimicrobial drug
d. competitive inhibitor
