paramecium
Explanation: 

Detailed explanation-1: -Malaria is caused by plasmodia-ancient, single-celled protozoans transmitted to humans by the bites of female Anopheles mosquitoes. Plasmodia parasites have complex life cycles involving vertebrate and insect hosts (Figure 6-1).

Detailed explanation-2: -Plasmodium falciparum is the type of malaria that most often causes severe and life-threatening malaria; this parasite is very common in many countries in Africa south of the Sahara desert. People who are heavily exposed to the bites of mosquitoes infected with P. falciparum are most at risk of dying from malaria.

Detailed explanation-3: -Malaria is caused by protozoa of the genus Plasmodium. Four species cause disease in humans: P falciparum, P vivax, P ovale and P malariae. Other species of plasmodia infect reptiles, birds and other mammals. Malaria is spread to humans by the bite of female mosquitoes of the genus Anopheles.

Detailed explanation-4: -In the case of malaria, the vector is the anopheline mosquito and the disease-causing organism is the malaria parasite. Humans and anopheline mosquitoes are both considered to be the parasite’s hosts.
