Question

Sporogony of malarial parasite occurs in
(A) Liver of man
(B) RBC s of man
(C) Salivary glands of mosquito
(D) Stomach wall of mosquito

Answer 1

Hint: Malaria is caused by the plasmodium which is the protozoan. It is transmitted by the saliva of the female anopheles’ mosquito when it bites the infected person and then to the normal healthy person. It is characterized by the alternate high and the low body temperature, headaches etc.

Complete answer:
Schizogony is defined as the multiple fission in a unicellular living being and produce many asexual offsprings. Sporogony is opposite to schizogony and it is the sexual stage that produces an enormous number of infecting parasites. Plasmodium finishes its life cycle in two hosts. The saliva of a contaminated anopheles mosquito discharge sporozoites into the circulation system that enter into the liver. Multiple fission in the sporozoites produces schizont that discharges a huge number of cryptozoites, which enter the solid liver cells again to shape metacryptozoites or meta crypto merozoites (Schizogony in liver).

Meta Cryptozoites enter the circulation system and replicate to shape merozoites which are delivered by break of RBCs (Schizogony in blood). A portion of the merozoites structure gametocytes (fit for sexual proliferation) which are sucked by mosquito alongside blood followed by gamete arrangement inside the stomach of mosquito and preparation to shape motile ookinete (Sporogony in stomach of mosquito). Choice D is right. The encysted ookinete is named as oocyst, which enters the agamic stage and bursts to deliver sporozoites in the body hole of the mosquito, which are put away in salivary organs till the mosquito to bite man.

Hence the correct answer is OPTION(D)

Note: The symptoms of the malaria are the alternate fever and the chill, fatigue, body aches, nausea, vomiting, feeling sick, pain in the abdomen or in the muscles, night sweats, morning shivering, diarrhea, mental confusion, higher heart rate.
