Immunology of Parasitic Diseases

question 1 of 2 course: Biomedical Science(Degree)

Q: In a research study, scientists create a genetically modified strain of Giardia lamblia that lacks the ability to express variant-specific surface proteins (VSPs). This strain is used to infect germ-free mice. Compared to infection with wild-type Giardia, what differences in infection outcome and host response would you PREDICT?

The mutant strain would be rapidly cleared due to an effective, non-evadable antibody response.
The mutant strain would be unable to colonize the intestine due to lack of adhesion molecules.
The mutant strain would cause more severe villous atrophy due to enhanced attachment.
The mutant strain would proliferate more rapidly due to reduced metabolic cost of VSP synthesis.

Did You Know?

Recombinant technology allows for the production of highly purified, specific viral antigens (like gp120 or p24) without contamination from other viral or cellular proteins. This increases the specificity of the test by reducing false-positive reactions.
