Question

In the life cycle of Plasmodium vivax, schizogony occurs in these cells of man (a) Hepatocytes (b) Adipocytes (c) Erythrocytes (d) Reticulocytes
A. b and a.
B. c and d
C. a and c
D. a and b

Answer 1

Hint: Plasmodium vivax is the parasitic bacteria and it is a human pathogen, where it causes a disease called malaria, and the life cycle of the parasite involves 2 members, that is humans and female anopheles mosquito.

Complete answer:
- The life cycle of plasmodium starts when a female anopheles mosquito is infected by the sporozoites when it feeds on an infected person.
- The infected mosquitoes later bites the healthy person, and it injects the sporozoite forms, where this enters the blood of the healthy person.
- From the blood the sporozoites enter the hepatic cells of the human.
- When in the hepatic cells, the sporozoite form is converted to extra erythrocyte schizogenic.
- These extra erythrocyte schizogeny, obtain the nutrition in the hepatic cells, and divide and release the merozoites to the bloodstream.
- These merozoites which are released from the hepatic cells, again enter the erythrocytes.
- In the erythrocytes, they develop into erythrocyte schizogony and release the schizonts, where these schizonts again rupture the blood cell and enter the fresh cell.
- During this male and female gametophytes are also released into the blood, where this enters the mosquito when it bites, and in the mosquito, these two gametophytes undergo mating and produce the sporozoites. Where the cycle of the plasmodium repeats.
So from the above question, schizonts formed in the hepatic cells, and erythrocytes.

Hence, the correct answer is option (C).

Note: Plasmodium vivax causes malaria in the humans, which occur in a stage-wise manner, wherein the first stage, there are chills, where there shivering of the body occur, and later it is the got stage, where the patient exhibits the high Fever, dry skin, headache, nausea vomiting, etc.
