QUESTION 1 Koch's postulates are used to identify a new emergent disease. 95% of injected, healthy animals showed disease. What's next?
Plate cells from diseased animals and pick the most abundant single colonies
Serial diluted bacteria from healthy animals and pick colonies with a unique appearance
Serially diluted bacteria from healthy and diseased subjects
Serially diluted bacteria and choose abundant, similar colonies in healthy subjects
A new candidate must be tested

2-What caused Pasteur's remarkable discovery?
Airborne microbes
Bacteria
Yeast
Mold
All answers are correct
3-Koch's postulates were applied to a new emergent disease. A candidate caused disease in every injected healthy subject. What needs to happen next?
Re-isolate the bacteria from the injected subject
More diseased animals have to be tested
The candidate must be isolated from injected, healthy animals
Bacteria from healthy and diseased animals must be compared
Tissue and filtrate from healthy subjects needs to be retested
4-What is the purpose of Koch's 4th postulate?
Identification of capsule forming cells
Test the candidate for infectivity
Test candidates to make sure most subjects develop disease
Monitor cell growth
No answers are correct
5-What does a single colony of a pathogenic microbe represent?
A clone
A species
A serotype
All answers are correct
No answers are correct
6-Redi proved biogenesis because?
The meat in the sealed jar eventually "went bad" or putrefied
Flies laid eggs on each other
No maggots were present in or on sealed jar but the meat putrefied
Maggots appeared on the meat in open jars
Redi did not prove biogenesis
7-How did Pasteur prove biogenesis?
Chopped off the top of the goose neck flask
Stoppered the top of the goose neck flask
Cultured airborne microorganisms
No answers are correct
All answers are correct
8-How did Koch choose candidates?
After serial dilution, he chose abundant single colonies from healthy subjects
Serial diluted bacteria from healthy animals and picked colonies with a unique appearance
After serial dilution, he chose abundant single colonies from diseased subjects that were not present in healthy subjects.
Serially diluted bacteria and chose abundant, similar colonies in healthy subjects
Serially diluted bacteria and chose colonies that are abundant in diseased and healthy animals
9-Which of the following describes the germ theory of disease?
Crossing over
Single colonies are clones
Biogenesis
Spontaneous generation
Prion disease
