Garnia (protist)
''Garnia'' is a genus of parasitic alveolates belonging to the phylum Apicomplexia. History The genus was created in 1971 by Lainson et al.Lainson R, Landau I and Shaw J.J. (1971) On a new family of non-pigmented parasites in the blood of reptiles: ''Garniidae'' fam. nov., (Coccidiida: Haemosporidiidea). Some species of the new genus ''Garnia''. Int. J. Parasitol. 1, (3-4) 241-244 Description Ulike members of the Plasmodiidae and Haemoproteidae, species in this genus do not produce pigment when developing in the erythrocytes. Species in this genus are distinguished from members of the Leucocytozoidae by their schizogony in the red and white cells of the peripheral blood. The vectors of this genus are not known but it is suspected that phlebotomine sandflies may act in this regard. The type species is '' Garnia gonatodi''. Hosts Species in this genus infect lizards. Geographic distribution This genus has been described in South America South America is a co ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Apicomplexa Genera
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 (''Cystoisospora ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

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]   |

Schizogony
Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts. The fission may be ''binary fission'', in which a single organism produces two parts, or ''multiple fission'', in which a single entity produces multiple parts. Binary fission Organisms in the domains of Archaea and Bacteria reproduce with binary fission. This form of asexual reproduction and cell division is also used by some organelles within eukaryotic organisms (e.g., mitochondria). Binary fission results in the reproduction of a living prokaryotic cell (or organelle) by dividing the cell into two parts, each with the potential to grow to the size of the original. Fission of prokaryotes The single DNA molecule first replicates, then attaches each copy to a differ ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Leucocytozoidae
''Leucocytozoon '' (or ''Leukocytozoon'') is a genus of parasitic Alveolata, alveolates belonging to the phylum Apicomplexa (which also includes the malaria parasites). The species of this genus use either blackflies (''Simulium'' species) or a biting midge as their definitive host and birds as their intermediate host. There are over 100 species in this genus. Over 100 species of birds have been recorded as hosts to these parasites. Life cycle Parasites in the genus ''Leucocytozoon'' have a life cycle that involves both a bird host, and a black fly (with the exception of ''Leucocytozoon caulleryi'' which cycles between a bird host and a biting midge). Parasites enter the bird host in a form called a sporozoite through the bite of the blood-sucking black fly. The sporozoites invade host cells in the liver where they undergo asexual replication, forming numerous daughter cells called merozoites within 4–5 days. The duration of this stage depends in part upon the species. In ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Erythrocyte
Red blood cells (RBCs), also referred to as red cells, red blood corpuscles (in humans or other animals not having nucleus in red blood cells), haematids, erythroid cells or erythrocytes (from Greek ''erythros'' for "red" and ''kytos'' for "hollow vessel", with ''-cyte'' translated as "cell" in modern usage), are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O2) to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or in fish the gills, and release it into tissues while squeezing through the body's capillaries. The cytoplasm of a red blood cell is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells and the blood. Each human red blood cell contains approximately 270 million hemoglobin molecules. The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiologi ...

Plasmodiidae
The Plasmodiidae are a family (biology), family of apicomplexan parasites, including the type genus ''Plasmodium'', which is responsible for malaria. This family was erected in 1903 by Mesnil and is one of the four families in the Order (biology), order Haemospororida. Diagnostic criteria The diagnostic criteria of the Plasmodiidae are: * Macrogametes and microgamonts develop independently * Meiosis is absent * Microgametocyte produces eight flagellated microgametes * Zygote is motile (known as an ookinete) * Conoid present in ookinete stage only * Sporozoites naked in oocyst (that is without a Apicomplexa lifecycle stages, sporocyst) * Sporozoites have three walls * Heteroxenous: Protozoal merogony, merogony and Apicomplexan life cycle#gametogony, gamogony occur in vertebrate host, and fertilization and sporogony in definitive host (a blood-sucking insect) * Hemozoin pigment is produced Taxonomy The family Plasmodiidae has three sister taxa in the order Haemospororida: the f ...
