Vinckeia
''Vinckeia'' is a subgenus of the genus ''Plasmodium'' — all of which are parasitic alveolates. The subgenus ''Vinckeia'' was created by Cyril Garnham in 1964 to accommodate the mammalian parasites other than those infecting the primates. Diagnostic features Species in this subgenus infect mammals other than the higher primates. Species infecting lemurs have since been included in this subgenus. This classification may not be correct. Schizonts: These do not fill the erythrocyte and do not show true stippling. They give rise normally to 8 or fewer merozoites. Schizogony normally takes three days or less. Merozoites: Gametocytes: These are spherical. Species in this subgenus The following is a list of species in subgenus ''Vinckeia'' and their hosts. *''Plasmodium achromaticum'' — insectivorous bat species *''Plasmodium aegyptensis'' — African grass rat (''Arvicanthis niloticus'') *''Plasmodium anomaluri'' — African flying squirrel ('' Anomalurus'' species) * ...

Plasmodium
''Plasmodium'' is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. The life cycles of ''Plasmodium'' species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. Parasites grow within a vertebrate body tissue (often the liver) before entering the bloodstream to infect red blood cells. The ensuing destruction of host red blood cells can result in malaria. During this infection, some parasites are picked up by a blood-feeding insect (mosquitoes in majority cases), continuing the life cycle. ''Plasmodium'' is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, ''Plasmodium'' is in the order Haemosporida and family Plasmodiidae. Over 200 species of ''Plasmodium'' have been described, many of which have been subdivided into 14 subgenera based on parasite morphology and host range.

''Plasmodium atheruri'' is a species of the genus ''Plasmodium'' subgenus ''Vinckeia''. As in all members of this genus, it is parasitic on vertebrate and insect hosts. The natural vertebrate host is the African porcupine ('' Atherurus africanus'') but it is possible to infect the large vesper mouse ('' Calomys callosus'') and '' Meriones unguiculatus''. Taxonomy This species was described in 1958 by den Berghe, Peel, Chardome and Lambrecht. Description Exoerythrocytic schizogony in this species usually lasts 4 to 6 days but occasionally schizonts have been found in the liver at day 8. Two types of infection are recognised: an acute form characterised by large trophozoites, schizonts with 8 to 16 merozoites, gametocytes and infectivity to ''Anopheles'' species; and a chronic form following the acute form by 15 to 21 days and which is characterized by small trophozoites and schizonts producing 4 merozoites.

Plasmodium Berghei
''Plasmodium berghei'' is a species in the genus ''Plasmodium'' subgenus ''Vinckeia''. It is a protozoan parasite that causes malaria in certain rodents. Originally, isolated from thicket rats in Central Africa, ''P. berghei'' is one of four ''Plasmodium'' species that have been described in African murine rodents, the others being '' P. chabaudi'', '' P. vinckei'', and '' P. yoelii''. Due to its ability to infect rodents and relative ease of genetic engineering, ''P. berghei'' is a popular model organism for the study of human malaria. Biology Like all malaria parasites of mammals, including the four human malaria parasites, ''P. berghei'' is transmitted by ''Anopheles'' mosquitoes and it infects the liver after being injected into the bloodstream by a bite of an infected female mosquito. After a short period (a few days) of development and multiplication, these parasites leave the liver and invade erythrocytes (red blood cells). The multiplication of the parasite in the bloo ...

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.

Plasmodium Bubalis
''Plasmodium bubalis'' is a parasite of the genus ''Plasmodium'' (subgenus '' Vinckeia'') which causes malaria in buffalo in India. Description Like other ''Plasmodium'' species, ''P. bubalis'' infects the red blood cells of its mammalian host. In the red blood cells, the parasite has several stages. The trophozoite stages begin as amoeboid in shape and measuring 1.2 to 1.8 μm. Larger trophozoites appear spherical and can measure up to 5.0 μm. Gametocytes occupy the entire red blood cell, and measure 6 to 8 μm in diameter. Role in disease ''P. bubalis'' causes malaria in buffalo.
