Question

• A. Plasmodium enters the human body as sporozoites through the bite of newly moulted (vector) female mosquito
• B. High fever recurring every three to four days
• C. Sporozoites initially multiply within the liver cells and then attack the RBCs resulting in their rupture
• D. When a female Anopheles mosquito bites an infected person, these parasites enter the mosquito's body and undergo further development

Answer 1

The correct option is A Plasmodium enters the human body as sporozoites through the bite of newly moulted (vector) female mosquito


Plasmodium enters the human body as sporozoites (infectious form) through the bite of infected female Anopheles mosquito.
The rupture of RBCs is associated with release of a toxic substance, hemozoin, which is responsible for the chill and high fever recurring every three to four days.
Sporozoites then enter into the liver through blood circulation. In the liver, they multiply sexually and rupture the liver cells and are released into the blood.
A female Anopheles mosquito bites an infected person, these parasites enter the mosquito’s body and undergo further development. The parasites multiply within them to form sporozoites that are stored in their salivary glands.
