Plasmodium Auffenbergi
''Plasmodium auffenbergi'' is a parasite of the genus ''Plasmodium'' subgenus ''Carinamoeba''. Like all ''Plasmodium'' species ''P. auffenbergi'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxonomy The parasite was first described by Telford in 2016 The meronts are cruciform or fan shaped. They measure 3.0 x 2.2 microns. They produce 2-5 merozoites. The gametocytes are spherical to ovoid and measure 4.7 x 3.9 microns. Male and female gametocytes do not differ in size or morphology. Distribution This species is found in the Philippines. Hosts This species infects the peacock monitor (''Varanus auffenbergi The peacock monitor (''Varanus auffenbergi)'', also known commonly as Auffenberg's monitor, is a species of small monitor lizard in the family Varanidae.

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] |
Carinamoeba
''Carinamoeba'' is a subgenus of the genus ''Plasmodium'' - all of which are parasitic unicellular eukaryotes. The subgenus was created in 1966 by Garnham.Garnham P.C.C. (1966) Malaria parasttes and other haemospordia. Oxford, Blackwell Species in this subgenus infect reptiles. Diagnostic features The original criterion for inclusion in this genus was the presence of small schizonts giving rise to 8 or less merozoites. The criteria were subsequently revised by Telford in 1988.Telford S. (1988) A contribution to the systematics of the reptilian malaria parasites, family Plasmodiidae (Apicomplexa: Haemosporina). Bulletin of the Florida State Museum Biological Sciences 34, 65-96 Species in the subgenus ''Carinamoeba'' have the following characteristics: Small schizonts giving rise to 8 or less merozoites The gametocytes like the schizonts are small. Species in this subgenus * ''Plasmodium attenuatum'' * ''Plasmodium auffenbergi'' * ''Plasmodium basilisci'' * ''Plasmodium cl ...

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 ...

Meront
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 ...

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 transmi ...

Varanus Auffenbergi
The peacock monitor (''Varanus auffenbergi)'', also known commonly as Auffenberg's monitor, is a species of small monitor lizard in the family Varanidae. The species, which belongs to the subgenus ''Odatria'', is endemic to Rote Island, Indonesia. (Retrieved Feb. 10, 2010.) Etymology The generic name ''Varanus'' is derived from the Arabic word ''waral'' ورل, (alternative spelling ''waran''= "lizard"). The name comes from a common semitic root ''ouran'', ''waran'', or ''waral'', meaning "lizard". The occasional habit of varanids to stand on their two hind legs and to appear to "monitor" their surroundings may have led to this name, as it was Latinized into ''Varanus''. The specific name ''auffenbergi'' honors US herpetologist Walter Auffenberg. Description The peacock monitor is one of the smaller monitor lizards, usually reaching a length of 60 cm (23.5 in). It is similar to the Timor monitor (''V. timorensis''), with some differentiation in the underside coloring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
