Question 1

The study of hantaviruses requires a biosafety level- 3 precautions.

Accepted Answer

A) True 
 B)False  False

Question 2

Where does the rabies virus reproduce? Using a specific example, explain the implication this has with the virus's incubation time and infection site.

Accepted Answer

The rabies virus propagates inside the brain, where once in high numbers can cause disease. This is an important consideration, because if a rabid dog bites an individual on the toe, the virus will likely have a longer incubation time than if the infection site was on his/her shoulder (nearer to the brain).

Question 3

Accepted Answer

A)  the organism gains access to the circulatory system and then invades the nervous system. 
B)  the endotoxin is released at the site of the infection and can travel to the nervous system. 
C)  endospores germinate in anoxic conditions. 
D)  of all of the above.
