Question

Consider the following statements Statement I: In the crop of female {Anopheles}, microgametes of {Plasmodium} are separated from the microgametocyte by ex-flagellation. Statement II: Schuffner's dots are believed to be the antigens released by {Plasmodium}. The correct answer is

• A. Both statements I and II are true
• B. Both statements I and II are false
• C. statement I is true, but statement II is false
• D. statement I is false, but statement II is true

Hint:

Schuffner's dots are diagnostic for infection by {Plasmodium vivax} and {Plasmodium ovale}.

Answer 1

The Correct Option is A

Concept: This concerns the sexual phase of the malaria parasite's life cycle in the mosquito and its pathology in the human host.
Explanation: Statement I is true: Exflagellation (the release of microgametes) occurs in the mosquito's midgut (crop). Statement II is true: Schuffner's dots are believed to be vesicles containing antigenic proteins, transported from the parasite to the surface of the infected red blood cell.
