Plasmodium Aegyptensis
''Plasmodium aegyptensis'' is a parasite of the genus ''Plasmodium'' subgenus ''Vinckeia'' which infects the Egyptian grass rat (''Arvicanthis niloticus''). The insect vector(s) for this species is not yet known. Description This species was first described in 1975 by Abd-el-Aziz ''et al.'' in Assiut from a group of Egyptian grass rats which had been captured. The parasite has not been isolated from other Egyptian grass rats since. As such, only the parasite stages which infect red blood cells of the vertebrate host have been described. When ''P. aegyptensis'' infects red blood cells in its mammalian host, it forms compact rings with a small food vacuole. Trophozoite forms are compact and rounded. Schizonts generally contain six merozoites (although 4 to 8 have been observed). When the parasites differentiate into gametocyte A gametocyte is a eukaryotic germ cell that divides by mitosis into other gametocytes or by meiosis into gametids during gametogenesis.

Parasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted parasitism, parasitoidism, and micropreda ...
