Plasmodium Lygosomae
''Plasmodium lygosomae'' is a parasite of the genus ''Plasmodium'' subgenus ''Carinamoeba''. Like all ''Plasmodium'' species ''P. lygosomae'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Description The parasite was first described by Laird in 1951. The schizonts give rise to 4 merozoites. The 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 ...s are elongate in form. Distribution This species is found in New Zealand. Hosts The only known host is the lizard '' Lygosoma moco''. This host species has recently been renamed '' Oligosoma moco''. References lygosomae {{plasmodium-stub ...

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 ...

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 ...

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. ...

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 ...

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 orga ...

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 ...

Lygosoma Moco
''Lygosoma'' is a genus of lizards, commonly known as supple skinks or writhing skinks, which are members of the family Scincidae. ''Lygosoma'' is the type genus of the subfamily Lygosominae. The common name, writhing skinks, refers to the way these stubby-legged animals move, snake-like but more slowly and more awkwardly. Geographic range Species of ''Lygosoma'' are found in India to southeast Asia. Taxonomy In the late 19th and early 20th century, ''Lygosoma'' was used as a "wastebin taxon", to which almost every newly described skink was assigned. Which specific species are contained within this genus is controversial because of its unresolved historic relation to two other closely-related genera: ''Mochlus'' and ''Lepidothyris.'' Currently, there are 16 known species in ''Lygosoma'', 15 known species in ''Mochlus'', and three known species in ''Lepidothyris''. However, some species under the latter two genera are often listed under ''Lygosoma'', and ''Lygosoma'' was re ...

Oligosoma Moco
The moko skink (''Oligosoma moco'') is a species of lizard in the family (biology), family Scincidae (skinks) that is endemism, endemic to New Zealand. ''Moko'' is the Māori language, Māori word for lizards in general. Distribution It is endemism, endemic to New Zealand and is found throughout the northeastern part of the North Island, though it is most common on the islands off the east coast of the North Island. To help protect the species, 50 skinks were released into the Rotoroa Island sanctuary in January 2014.https://www.facebook.com/events/294797780730468/ retrieved 12 June 2015 Description The colour and patterns are variable, but the overall colour is coppery or olive brown and it usually has an even edged dark brown stripe along the side, bordered cream or white on the top and bottom. Some individuals are very dark. It has distinctive long toes and tail and grows to a maximum of 18 cm. The very long tail can make up over half the total body length. Ecology Moko ...
