Plasmodium Marginatum
''Plasmodium marginatum'' is a parasite of the genus ''Plasmodium'' subgenus ''Sauramoeba''. As in all ''Plasmodium'' species, ''P. marginatum'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxonomy The parasite was first described by Telford in 1979.Telford SR Jr. (1979) A taxonomic reconsideration of some ''Plasmodium'' species from iguanid lizards. Ann. Parasitol. Hum. Comp. 54(2):129-144 This species had previously been considered to be ''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 sp ...''. Description All stages tend to lie along the erythrocyte margin. While mature schizonts appear to be like flattened fans with 3 to 8 merozoites, immature schizonts are highly amoeboid. Gametocytes are smaller than er ... [...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. Evolutionary relationships among different ''Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauramoeba
''Sauramoeba'' is a subgenus of the genus ''Plasmodium'', all of which are parasitic eukaryotes. The subgenus was created in 1966 by Garnham. Species in this subgenus infect reptiles. Description The original criterion for inclusion in this genus was the presence of large schizonts giving rise to 12 or more merozoites. The criteria were subsequently revised by Telford in 1988. The type species of this subgenus is ''Plasmodium diploglossi ''Plasmodium diploglossi'' is a parasite of the genus ''Plasmodium'' subgenus '' Sauramoeba''. As in all ''Plasmodium'' species, ''P. diploglossi'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxo ...''. Species in the subgenus ''Sauramoeba'' have the following characteristics: Large schizonts giving rise to 12 or more merozoites The gametocytes like the schizonts are large.

Vertebrate
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () ( chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around ...

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] |
Anole
Dactyloidae are a family of lizards commonly known as anoles () and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloidae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with ''Polychrus'' (bush anoles), but the latter genus is not closely related to the true anoles. Anoles are small to fairly large lizards, typically green or brownish, but their color varies depending on species and many can also change it. In most species at least the male has a dewlap, an often brightly colored flap of skin that extends from the throat/neck and is used in displays. Anoles share several characteristics with geckos, including details of the foot structure (for climbing) and the ability to voluntarily break off the tail (to escape predators), but they are only very distantly related, anoles being part of Iguania. ...
