Giovannolaia
''Giovanolaia'' is a subgenus of the genus ''Plasmodium'' created by Corradetti ''et al.'' in 1963. The parasites within this subgenus infect birds. This subgenus was shown on the basis of DNA analysis to be polyphyletic. This is unsurprising – it has been a wastebasket taxon. A revision of this subgenus on a morphological basis by Landau ''et al.'' moved several of the species in this subgenus into a new subgenus '' Papernaia''. Description Species in the subgenus ''Giovanolaia'' have the following characteristics: Schizonts contain plentiful cytoplasm, are larger than the host cell nucleus and frequently displace it. They are found only in mature erythrocytes. Gametocytes are elongated. Both gametocytes and schizonts are stretched along the red cell nucleus. Exoerythrocytic schizogony occurs in the mononuclear phagocyte Monocytes are a type of leukocyte or white blood cell. They are the largest type of leukocyte in blood and can differentiate into macrophages and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Evolutionary relationships among different ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Papernaia
''Papernaia'' is a subgenus of the genus ''Plasmodium'', all of which are parasitic protozoa. The subgenus was created in 2010 by Landau ''et al''. Species in this subgenus infect birds with malaria. __TOC__ Subgenus characteristics The gametocytes are elongated. The schizonts apically or lateroapically placed and are rounded or irregularly shaped. The host nucleus may be tilted. History This subgenus was created on the basis of morphology. It may be subsequently revised when more information becomes available from DNA studies. It was created to deal with the existing problems with the existing subgenera ''Giovannolaia'' and ''Novyella''. Both genera were originally defined on the basis of morphology but subsequent DNA analysis showed them both to be polyphetic. These subgenera have been revised and several of the species originally placed within those subgenera have now been moved to ''Papernaia''. The name of this subgenus was chosen to honour the malariologist Ilan Paper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
