Malaria is caused by plasmodium protozoa. The life cycle of plasmodium requires two hosts : Man and Mosquitoes. Sporozoites are infectious stage of malarial parasites. When female mosquito bites the human, these enter the blood stream. Inside the body these have an Erythrocytic and Exo erythrocytic cycle. When healthy mosquito bites such an infected human, these agents enter the mosquitoes body and starts its sexual reproduction which transforms into various forms and reside in the salivary gland. This healthy mosquito is now a carrier and if this again bites any human, the same cycle continues.
