An immunogen that is going to be used for vaccination against Naegleria has been
sitting out in the sun. It is quite likely that it has become denatured. The authorities want
to know how this might affect the efficacy of the vaccine. You say:
- Neither the T cell response nor the antibody response will be affected
- T cells generated with this denatured immunogen will not respond to the native
Naegleria molecule
- Antibodies cannot be generated to Naegleria molecules
, Parasitology Exam 1 Practice Questions And
Answers
- Antibodies generated to this denatured immunogen will not bind to the native molecule
on Naegleria
- None of the above is correct. Antibodies generated to this denatured immunogen will not
bind to the native molecule
on Naegleria

Two patients were suspected of exposure to a rare parasite. When sera from these
patients were analyzed, patient A had mostly IgM antibodies to the infectious agent while
patient B had a very high titer of mostly IgG. What can you conclude from these results?
