Amoebas and some parasites, including those which cause malaria and sleeping- sickness are different forms of which microscopic single-celled organisms?
Human genetic resistance to malaria cells from invasion by "Plasmodium" parasites or replication of parasites within the red blood cell. These inherited changes to hemoglobin or other characteristic proteins, which are critical and rather invariant features of mammalian biochemistry, usually cause some kind of inherited disease. Therefore, they are commonly referred to by the names of the blood disorders associated with them, including sickle-cell disease, thalassemia, glucose-6-phosphate dehydrogenase deficiency, and others. These blood disorders cause increased morbidity and mortality in areas of the world where malaria is less prevalent. Microscopic parasites, like viruses, protozoans that cause malaria, and others, cannot replicate on their own and
Malaria of malaria, zika, dengue and yellow fever). Nearly 200 parasitic "Plasmodium" species have been identified that infect birds, reptiles, and other mammals, and about 30 species naturally infect non-human primates. Some malaria parasites that affect non-human primates (NHP) serve as model organisms for human malarial parasites, such as "P. coatneyi" (a model for "P. falciparum") and "P. cynomolgi" ("P. vivax"). Diagnostic techniques used to detect parasites in NHP are similar to those employed for humans. Malaria parasites that infect rodents are widely used as models in research, such as "P. berghei". Avian malaria primarily affects species of the order Passeriformes,
