Plasmodium Tropiduri
''Plasmodium tropiduri'' is a parasite of the genus ''Plasmodium'' subgenus '' Lacertaemoba''. As in all ''Plasmodium'' species, ''P. tropiduri'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. This species is closely related to ''Plasmodium floridense'' and '' Plasmodium minasense''. Taxonomy The parasite was first described by Aragão and Neiva in 1909. It had been previous discovered by Carlos Chagas but not formally described. Later it was realised that this species was in fact a species complex. This complex was divided into a number of subspecies by Telford in 1979. Subspecies * ''Plasmodium tropiduri aquaticum'' is found in ''Anolis lionotus'' and '' Anolis poecilopus'' in Panama and Costa Rica. Schizonts are found mostly in pro-erythrocytes, are smaller than erythrocyte nuclei, have 4 to 14 nuclei and contain pigment. Gametocytes occur in erythrocytes, are smaller than erythrocyte nuclei and contain pigment. * ''Plasmodium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Schizont
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 ...

Tropidurus Torquatus
''Tropidurus torquatus'' is a species of lizard in the family Tropiduridae, the Neotropical ground lizards. Its common name is Amazon lava lizard.Embert, D. 2010''Tropidurus torquatus''.In: IUCN 2012. IUCN Red List of Threatened Species. Version 2012.2. Etymology The specific name, ''Tropidurus torquatus'', is Latin meaning "adorned with a neck chain or collar". Geographic range It is native to South America, where it can be found in Argentina, Bolivia, Brazil, Colombia, French Guiana, Guyana, and Suriname. It is one of the most widely distributed species of genus '' Tropidurus''. Description This is a medium-sized lizard with a relatively large head. Its scales are overlapping. The reproductively mature female ranges from snout-to-vent length (SVL). One sample of adult males had a mean SVL of , while another found a mean SVL of .

Tropidurus
''Tropidurus'' is a genus of reptiles. The genus includes many species of Neotropical ground lizards (family Tropiduridae). ''Tropidurus'' is the type genus of the family Tropiduridae. Geographic range and habitat Species in the genus ''Tropidurus'' are found on the South American mainland, especially in the Amazon Rainforest, but also in more arid regions. Common name No widely common name is used solely for species of the genus ''Tropidurus''. In their native range, they are simply called "Lagartixa" as are most similar animals. If anything, the Brazilian term ''calango'' is used to particularly refer to lizards of the genus ''Tropidurus''. Taxonomy The genus ''Tropidurus'' contains 30 described species, but new ones continue to be discovered. An additional seven species—the Galápagos lava lizards endemic to the Galápagos Islands—are sometimes placed here, too, but more commonly separated in the genus '' Microlophus'', instead. Similarly, the green thornyta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anolis Biporcatus
''Anolis biporcatus'', also known as the neotropical green anole or giant green anole, is a species of anole. It is found in forests, both disturbed and undisturbed, in Mexico, Central America, Colombia and Venezuela. More southern populations, in southwestern Colombia and western Ecuador, were recognized as a separate species, '' A. parvauritus'', in 2017. As suggested by its common names, the neotropical green or giant green anole is mostly green in color and relatively large, among the largest anoles in the mainland of the Americas. Males have a snout–vent length of about and the females, which grow slightly larger, about . In general, there is little sexual dimorphism in this species. The tail is roughly double the length of the snout-to-vent. See also *List of Anolis lizards The large lizard genus ''Anolis ''contains around 436 accepted anole () species, which have been considered in a number of subgroups, or clades such as ''carolinensis'' and ''isolepis''.

Gametocyte
A gametocyte is a eukaryotic germ cell that divides by mitosis into other gametocytes or by meiosis into gametids during gametogenesis. Male gametocytes are called ''spermatocytes'', and female gametocytes are called ''oocytes''. Development The development of gametogonia to primary gametocytes is called gametocytogenesis. The further development of primary gametocytes to secondary gametocytes is a part of gametidogenesis. Gametogenesis is the formation or production of gametes (taking place during meiosis). The development and maturation of sex cells also takes place during meiosis. Gametogenesis is also the process of formation in male and female gametes that occur in the gonads (ovary and testis). Both male and female produce gametes. Male gametocytes are called spermatocytes and female gametocytes are called oocytes. The term gametocyte is also used, for example, when talking about gametocytes of species like ''Plasmodium falciparum'' or ''Plasmodium vivax'', which transm ...

Plasmodium Minasense
''Plasmodium minasense'' is a parasite of the genus ''Plasmodium'' subgenus ''Carinamoeba''. Like all ''Plasmodium'' species ''P. minasense'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are lizards. Taxonomy The original description of this species was by Carini and Rudolphi in 1912Carini, A. y Rudoph, M.
