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 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.
D. obtain a sample of blood or other body fluid from a diseased animal.
Which ONE of the following best describes the abbreviation ‘MIC’?
Select one:
A.
The lowest concentration at which no microbial growth is detected
B.
The lowest concentration that indicates whether an antibiotic would be effective or not
C.
The lowest concentration which is not toxic to the host
D.
The lowest concentration which is least effective against the organism
E.
The lowest concentration which kills the organism
