Question 8 options:
A)
something foreign in the body
B)
a substance that elicits an immune response
C)
a chemical that combines with antibodies
D)
a pathogen

1. Analyze the data provided and answer the following:
a) Compare your body’s response to antigen “A” both times you were exposed. Describe at least two ways in which the body’s response is different.
b) Why might your body’s second response to “antigen A” have been so different? What changes may have occurred to your immune system?
The immune system of a person is supressed. He was found positive for a pathogen in the diagnostic test ELISA.(a) Name the disease, the patient is suffering from.(b) Which pathogen is identified by ELISA test?(c) Which cells of the body are attacked by the pathogen?(d) Suggest preventive measure of the infection.
