Haemamoeba Metchnikovi
''Haemamoeba'' is a subgenus of the genus '' Plasmodium'' — all of which are parasites. The subgenus was created in 1963 by created by Corradetti ''et al.''. Species in this subgenus infect birds. __TOC__ Diagnostic features Species in the subgenus ''Haemamoeba'' have the following characteristics: Mature schizonts are larger than the host cell nucleus and commonly displace it. Gametocytes are large, round, oval or irregular in shape and are substantially larger than the host nucleus. Species in this subgenus * '' Plasmodium cathemerium'' * ''Plasmodium coggeshalli'' * '' Plasmodium elongatum'' * '' Plasmodium gallinaceum'' * ''Plasmodium giovannolai'' * ''Plasmodium griffithsi'' * '' Plasmodium lutzi'' * ''Plasmodium matutinum'' * ''Plasmodium parvulum'' * ''Plasmodium relictum ''Plasmodium relictum'' is a species in the genus '' Plasmodium,'' subgenus ''Haemamoeba''.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Plasmodium Gallinaceum
''Plasmodium gallinaceum'' is a species of the genus '' Plasmodium'' (subgenus ''Haemamoeba'') that causes malaria in poultry. Description This species was described by Alexandre Joseph Emile Brumpt (1877–1951) a French professor of parasitology during a trip to Ceylon (now Sri Lanka). Vectors '' Aedes aegypti'' is a vector. Virulence factors Circumsporozoite protein Circumsporozoite protein (CSP) is a secreted protein of the sporozoite stage of the malaria parasite (''Plasmodium'' sp.) and is the antigenic target of RTS,S and other malaria vaccines. The amino-acid sequence of CSP consists of an immunodominan ... (CSP) is required for host invasion. Warburg ''et al.'', 1992 provides a monoclonal antibody against CSP and demonstrates efficacy. The complete inhibition of sporozoite colonization of ''Aedes aegypti'' salivary glands they achieved could be due to the antibody itself blocking contact between the sporozoites and the gland surface, however the antibo ...

Plasmodium Tejerai
''Plasmodium tejerai'' is a parasite of the genus ''Plasmodium'' subgenus ''Haemamoeba''. Like all ''Plasmodium'' species ''P. tejerai'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are birds. Taxonomy The parasite was first described by Gabaldon and Ulloa in 1977. Distribution This parasite is found in Brazil and Venezuela. Vectors Not known. Clinical features and host pathology This organism infects the domestic turkey (''Meleagris gallopavo'') and the South American penguin (''Spheniscus magellanicus''). Morphologically this parasite resembles ''Plasmodium relictum'' closely. In the penguin infection may be fatal with splenomegaly, hepatomegaly, hydropericardium and pulmonary oedema.

Plasmodium Relictum
''Plasmodium relictum'' is a species in the genus '' Plasmodium,'' subgenus ''Haemamoeba''. It is a parasite, and the most common cause of malaria in birds. Like all ''Plasmodium'' species, ''P. relictum'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are birds. Distribution ''P. relictum'' is geographically widespread, and is the most widespread malaria parasite of birds. Climate change is broadening its distribution further and is expected to continue to do so, including into higher elevations. Hosts Avian ''P. relictum'' infects a wide variety of birds including birds from various orders. Infections in numerous wild birds and experimental animals have been described including partridges, canaries, chickens, ducks, pigeons and ''Spheniscus magellanicus'' (Magellanic penguins). . . Experimental attempts to infect owls Owls are birds from the Order (biology), order Strigiformes (), which includes over 200 species of mos ...

Plasmodium Parvulum
''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 Hematophagy, blood-feeding insect host (biology), 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 (Mosquito, 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 ...

''Plasmodium matutinum'' is a parasite of the genus ''Plasmodium'' subgenus ''Haemamoeba''. Like all ''Plasmodium'' species ''P. matutinum'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are birds. Taxonomy The parasite was first described by Huff in 1937.Huff CG (1937) A new variety of ''Plasmodium relictum'' from the robin.
