Overview of spp. and Animal Models in Malaria Research.

Malaria is a parasitic disease caused by protozoan species of the genus and transmitted by female mosquitos of the genus and other Culicidae. Most of the parasites of the genus are highly species specific with more than 200 species described affecting different species of mammals, birds, and reptiles. species strictly affecting humans are , , , and More recently, and other nonhuman primate plasmodia were found to naturally infect humans. Currently, malaria occurs mostly in poor tropical and subtropical areas of the world, and in many of these countries it is the leading cause of illness and death. For more than 100 y, animal models, have played a major role in our understanding of malaria biology. Avian species were the first to be used as models to study human malaria. Malaria parasite biology and immunity were first studied using mainly and . Rodent malarias, particularly and , have been used extensively as models to study malaria in mammals. Several species of from nonhuman primates have been used as surrogate models to study human malaria immunology, pathogenesis, candidate vaccines, and treatments. , , and are important models for studying malaria produced by and , while is used as a model for study- ing severe malaria. Other nonhuman primate malarias used in research are , , , , and . Very few nonhuman primate species can develop an infection with human malarias. Macaques in general are resistant to infection with , , , and . Only apes and a few species of New World monkeys can support infection with human malarias. Herein we review the most common, and some less common, avian, reptile, and mammal plasmodia species used as models to study human malaria.
