Question

Where will you look for the sporozoites of the malarial parasite?

• A. Salivary glands of freshly moulted female Anopheles mosquito.
• B. Saliva of infected female Anopheles mosquito.
• C. Red blood corpuscles of humans suffering from malaria.
• D. Spleen of infected humans.

Answer 1

The correct option is B Saliva of infected female Anopheles mosquito.

Freshly moulted female anopheles mosquito will not have spores of the malarial parasite, because spores originate only when they feed on the blood of the infected host. Sporozoite formation does not take place in RBC. Spleen is the graveyard of RBC and Plasmodium do not infect spleen cells. Correct Answer is option B. Malarial parasite spores are present in infected female anopheles, which is transmitted to another host when they feed on blood.
