Plasmodium Tomodoni
''Plasmodium tomodoni'' is a parasite of the genus ''Plasmodium''. As in all ''Plasmodium'' species, ''P. tomodoni'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxonomy The parasite was first described by Pessoa and Fleury in 1968.Pessoa S.B. and Fleury G.C. (1968) ''Plasmodium tomodoni'' sp. n. parasita da serpente ''Tomodon dorsatus'' D & B. Rev. Brasil Biol. 28: 525-530 Distribution This species is found in Brazil. Hosts This species infects snakes. The other two species infecting snakes are ''Plasmodium pessoai'' and '' Plasmodium wenyoni''. The original host this species was described from was a ''Tomodon dorsatus ''Tomodon'' is a monotypic genus of colubrid snakes,which includes the species Tomodon dorsalis, and is endemic to South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with ...'' from Brazil.

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 ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebrate
Vertebrates () comprise all animal taxon, taxa within the subphylum Vertebrata () (chordates with vertebral column, 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: * Agnatha, jawless fish, which include hagfish and lampreys * Gnathostomata, jawed vertebrates, which include: ** Chondrichthyes, cartilaginous fish (sharks, Batoidea, rays, and Chimaeriformes, ratfish) ** Euteleostomi, bony vertebrates, which include: *** Actinopterygii, ray-fins (the majority of living Osteichthyes, bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant taxon, 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 a ... [...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 ...

Plasmodium Pessoai
''Plasmodium pessoai'' is a parasite of the genus ''Plasmodium''. As in all ''Plasmodium'' species, ''P. pessoai'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxonomy The parasite was first described by Ayala ''et al.'' in 1978.Ayala S.C., Moreno-Robles E., Bolaños-Herrera, R. (1978) ''Plasmodium pessoai'' sp. n. procedentes de dos serpientes costarricenses. J. Parasitol. 64(2)330-335 The species is named after Dr Samuel B Pessoa - a parasitologist at the Instituto Butantan, São Paulo, Brazil. Morphologically this species appears to be related to ''Plasmodium aurulentum''. Description The gametocytes are small and sausage shaped (10.4 x 4.6 micrometres) Immature schizonts often contain a digestive vacuole. Mature schizonts are spherical or bouquet-shaped and produce 22 - 32 merozoites. They may possess an intensely staining magenta or rose-coloured substance in the matrix of the surrounding vacuole.

Plasmodium Wenyoni
''Plasmodium wenyoni'' is a parasite of the genus ''Plasmodium''. As in all ''Plasmodium'' species, ''P. wenyoni'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxonomy The parasite was first described by Garnham in 1965.Garnham P.C. (1965) ''Plasmodium wenyoni'' sp. nov., a malaria parasite of a Brazilian snake. Trans R Soc Trop Med Hyg. 59:277-279 The original host was a ''Thamnodynastes pallidus'' that died in a London zoo in 1934. Distribution This species is found in Brazil. Hosts The only known hosts of this species are snakes. The insect vectors for this species are mosquitoes of the genus ''Culex ''Culex'' is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals.
