Hemolivia
''Hemolivia'' (also spelled ''Haemolivia'') is a genus of the phylum Apicomplexia. History This genus was described in 1990 by Petit ''et al''. The type species is '' Hemolivia stellata''. Molecular data on ''H. stellata'' were provided in 2015 by Karadjian, Chavatte and Landau, from a 25-year-old archived smear of crushed tick ('' Amblyomma rotondatum''). ''Hepatozoon argantis'' Garnham, 1954 was reassigned to ''Hemolivia'' as '' Hemolivia argantis'' (Garnham, 1954) Karadjian, Chavatte and Landau, 2015. Characteristics of the genus The species in this genus are haemogregarines and infect exothermic vertebrates. They have erythrocytic gamogony, both erythrocytic and extra-erythrocytic merogony and cystogony. The definitive hosts are ixodid ticks. Sporogony occurs in two phases. In the first phase conjugation and fertilization occur within the tick gut. This is followed by the formation of oocysts and the generation of sporokinetes. In the second phase the sporokinetes i ...

Haemogregarine
''Adeleorina'' is a suborder of parasites in the phylum Apicomplexa. History Léger proposed this taxon in 1911. The first species identified was '' Dactylosoma ranarum'' by Lankester (1871) in a frog in Europe. It was initially called ''Undulina ranarum'', but this was changed in 1882 to ''Drepanidium ranarum''. This species was subsequently moved to the genus ''Dactylosoma''. Canine hepatozoonosis was first described in India in 1905 by James. The organism was named ''Leukocytozoon canis''. The vector was identified in 1907 by Christopher to be the brown dog tick (''Rhipicephalus sanguineus''). The genus '' Hepatozoon'' was created by Miller in 1908 for a parasite of the white rat (''Rattus norvegicus'') that underwent merogony in the liver and sporogony in the mite '' Laelap echidinus''. Ledger initially placed this genus in the family Haemogregarinidae, but Wenyon subsequently removed it and placed it in the newly created taxon Hepatozoidae in 1926. Life cycle All species ...

Testudo Marginata
The marginated tortoise (''Testudo marginata'') is a species of tortoise in the family Testudinidae. The species is endemic to Greece, Italy, and the Balkans in Southern Europe. It is the largest European tortoise. The marginated tortoise is herbivorous, and brumates for the winter. Taxonomy The marginated tortoise was formally described by German naturalist Johann David Schoepff in 1789; its specific epithet ''marginata'' is a straightforward derivation from the Latin term for 'marginated'. The nominate subspecies is the Greek marginated tortoise, ''Testudo marginata marginata''. Three additional subspecies of marginated tortoises have been named: The Sardinian marginated tortoise (''T. m. sarda'') is the name usually used to separate the population on the island of Sardinia. These tortoises have less strongly bent tiles in the posterior of their carapaces, and the posterior of the carapace is almost smooth compared with the saw-like ''T. m. marginata''. Clearly distinct ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testudo Graeca
The Greek tortoise (''Testudo graeca''), also known commonly as the spur-thighed tortoise, is a species of tortoise in the family Testudinidae. ''Testudo graeca'' is one of five species of Mediterranean tortoises (genera '' Testudo'' and '' Agrionemys''). The other four species are Hermann's tortoise (''T. hermanni''), the Egyptian tortoise (''T. kleinmanni''), the marginated tortoise (''T. marginata''), and the Russian tortoise (''A. horsfieldii''). The Greek tortoise is a very long-lived animal, achieving a lifespan upwards of 125 years, with some unverified reports up to 200 years. Geographic range The Greek tortoise's geographic range includes North Africa, Southern Europe, and Southwest Asia. It is prevalent in the Black Sea coast of the Caucasus (from Anapa, Russia, to Sukhumi, Abkhazia, Georgia, to the south), as well as in other regions of Georgia, Armenia, Iran, and Azerbaijan. Evolution The oldest known definitive fossil is from the Early Pliocene of Greece, but sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiliqua Rugosa
''Tiliqua rugosa'', most commonly known as the shingleback lizard or bobtail lizard, is a short-tailed, slow-moving species of blue-tongued skink (genus ''Tiliqua'') endemic to Australia. It is commonly known as the shingleback or sleepy lizard. Three of its four recognised subspecies are found in Western Australia, where the ''bobtail'' name is most frequently used. The fourth subspecies, ''T. rugosa asper,'' is the only one native to eastern Australia, where it goes by the common name of the eastern shingleback. Apart from bobtail and shingleback, a variety of other common names are used in different states, including two-headed skink, stumpy-tailed skink, or , pinecone lizard. The Noongar Aboriginal people refer to ''rugosa'' as ''yoorn'' in their language. ''T. rugosa'' has a short, wide, stumpy tail that resembles its head and may serve the purpose of confusing predators. The tail also contains fat reserves, which are drawn upon during brumation in winter, during which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merozoite
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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
