Plasmodium yoelii is a parasite of the genus Plasmodium subgenus Vinckeia.
Like all Plasmodium species P. yoelii has both vertebrate and insect hosts. The vertebrate hosts for this parasite are mammals.
Description
This species was described in 1968 by Landau, Michel and Adam.
Geographical occurrence
This species occurs in Africa.
Vectors
The natural vectors of this species are not currently known. One possible is the Female Anopheles mosquito which serves as a vector for Plasmodium Vivax.
Clinical features and host pathology
This species infects Thamnonys rutilans
Notes
Three subspecies are recognised: P. yoelii killicki, P. yoelii nigeriensis and P. yoelii yoelli.
Its most notable feature is that it is used in the laboratory to infect mice, as a model of human malaria, particularly with respect to the immune response.
It is advantageous to have a whole-animal model of malaria because often it is difficult to know which factors to study in vitro, particularly in a complex system like the immune system. Moreover, for many experiments it is not ethical or practical to use humans.
One of the special things about this particular model is that it has two strains with vastly different pathogenicity. These are generally referred to as the "lethal" and "non-lethal" strains of the species. Comparison of these two strains can be used to deduce which factors may contribute to more serious malaria infections in humans.
