Detailed explanation-1: -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-2: -The causative agents of malaria are unicellular protozoan parasites belonging to the genus Plasmodium. These parasites infect not only humans but also other vertebrates, from reptiles and birds to mammals.

Detailed explanation-3: -A significant number of protists are pathogenic parasites that must infect other organisms to survive and propagate. Protist parasites include the causative agents of malaria, African sleeping sickness, and waterborne gastroenteritis in humans.

Detailed explanation-4: -Pathogenic protists are parasites that infect other organisms, like animals and human beings, and cause harm to their hosts. Some examples of pathogenic protists are Trypanosoma brucei, T. cruzi, Plasmodium falciparum, and Toxoplasma gondii. Sleeping sickness is caused by the pathogenic protist T.
