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 ...

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] |
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'' ...

Phylum
In biology, a phylum (; plural: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. Depending on definitions, the animal kingdom Animalia contains about 31 phyla, the plant kingdom Plantae contains about 14 phyla, and the fungus kingdom Fungi contains about 8 phyla. Current research in phylogenetics is uncovering the relationships between phyla, which are contained in larger clades, like Ecdysozoa and Embryophyta. General description The term phylum was coined in 1866 by Ernst Haeckel from the Greek (, "race, stock"), related to (, "tribe, clan"). Haeckel noted that species constantly evolved into new species that seemed to retain few consistent features among themselves and therefore few features that distinguished them as a group ("a self-contained unity" ...

Apicomplexa
The Apicomplexa (also called Apicomplexia) are a large phylum of parasitic alveolates. Most of them possess a unique form of organelle that comprises a type of non-photosynthetic plastid called an apicoplast, and an apical complex structure. The organelle is an adaptation that the apicomplexan applies in penetration of a host cell. The Apicomplexa are unicellular and spore-forming. All species are obligate endoparasites of animals, except '' Nephromyces'', a symbiont in marine animals, originally classified as a chytrid fungus. Motile structures such as flagella or pseudopods are present only in certain gamete stages. The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines, piroplasms, haemogregarines, and plasmodia. Diseases caused by Apicomplexa include: * Babesiosis (''Babesia'') * Malaria (''Plasmodium'') * Cryptosporidiosis (''Cryptosporidium parvum'') * Cyclosporiasis (''Cyclospora cayetanensis'') * Cystoisosporiasis (''Cystoisosp ...

Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleohaemoproteus
''Paleohaemoproteus'' is an extinct genus of ''Haemoproteus'' like organisms. The type species and only known example is that of an isolate found in the abdominal cavity of a female biting midge trapped 100 million years ago in amber found in Myanmar. The amber has been dated to the Early Cretaceous The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of th ... epoch.
