Haemocystidium
''Haemocystidium'' is a genus of parasitic alveolates belonging to the phylum Apicomplexia. History The genus ''Haemocystidium'' was created to give a name to the haemoproteid of a gecko belonging to the genus '' Hemidactylus'' in Sri Lanka by Castellani and Willey in 1904. A second species in this genus was described in 1909 by Johnston and Cleland who found pigmented gametocytes in the blood of the Australian tortoise ''Chelodina longicollis''. These species were transferred to ''Haemoproteus'' in 1926 by Wenyon. The genus was resurrected by Garnham in 1966 when he created a new generic name - '' Simondia'' - for the haemoproteids of chelonians. He followed the opinions of Wenyon, Hewitt and DeGiusti and suggested that all these parasites belonged to the one species - '' Simondia metchnikovi''. He retained the name ''Haemocystidium'' for the haemoproteids of lizards. Levine and Campbell in 1971 moved all the species in ''Simondia'' and ''Haemocystidium'' into ''Haemoproteus'' ...

Haemoproteus
''Haemoproteus'' is a genus of alveolates that are parasitic in birds, reptiles and amphibians. Its name is derived from Greek: ''Haima'', "blood", and ''Proteus'', a sea god who had the power of assuming different shapes. The name ''Haemoproteus'' was first used in the description of '' H. columbae'' in the blood of the pigeon ''Columba livia'' by Kruse in 1890. This was also the first description of this genus. Two other genera — '' Halteridium'' and '' Simondia'' — are now considered to be synonyms of ''Haemoproteus''. The protozoa are intracellular parasites that infect the erythrocytes. They are transmitted by blood sucking insects including mosquitoes, biting midges (''Culicoides''), louse flies (''Hippoboscidae'') and horse-flies (" tabanids", "tabanid flies"). Infection with this genus is sometimes known as pseudomalaria because of the parasites' similarities with ''Plasmodium'' species. Within the genus there are at least 173 species, 5 varieties and 1 subspecies. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haemosporida
The Haemosporida (sometimes called Haemospororida) are an order of intraerythrocytic parasitic alveolates. Taxonomy Over 500 species are in this order, organised into four families: the Garniidae, the Haemoproteidae, the Leucocytozoidae, and the Plasmodiidae. The majority of the species lie within three genera: ''Haemoproteus'', ''Leucocytozoon'', and ''Plasmodium''. The Haemoproteidae and the Plasmodiidae both produce pigment. These families have been placed in the suborder Laveraniina. Neither the Haemoproteidae nor the Leucocytozoidae have an asexual cycle in the peripheral blood. The Garniidae do not produce pigment, but do have an asexual cycle in the blood. The taxa in detail are: *Family Garniidae ** Genus '' Fallisia'' Lainson, Landau & Shaw 1974 *** Subgenus '' Fallisia'' *** Subgenus '' Plasmodioides'' Gabaldon, Ulloa and Zerpa 1985 ** Genus '' Garnia'' Lainson, Landau and Shaw 1971 ** Genus '' Progarnia'' Lainson 1995 *Family Haemoproteidae ** Genus '' Johnsprenti ...

Chelonia (order)
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates ...

Meront
Apicomplexans, a group of intracellular parasites, have life cycle stages that allow them to survive the wide variety of environments they are exposed to during their complex life cycle. Each stage in the life cycle of an apicomplexan organism is typified by a ''cellular variety'' with a distinct morphology and biochemistry. Not all apicomplexa develop all the following cellular varieties and division methods. This presentation is intended as an outline of a hypothetical generalised apicomplexan organism. Methods of asexual replication Apicomplexans (sporozoans) replicate via ways of multiple fission (also known as schizogony). These ways include , and , although the latter is sometimes referred to as schizogony, despite its general meaning. Merogony is an asexually reproductive process of apicomplexa. After infecting a host cell, a trophozoite ( see glossary below) increases in size while repeatedly replicating its nucleus and other organelles. During this process, the org ...

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.
