Plasmodium Cephalophi
''Plasmodium cephalophi'' is a parasite of the genus ''Plasmodium'' subgenus ''Vinckeia''. As in all ''Plasmodium'' species, ''P. cephalophi'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are mammals. Taxonomy The parasite was first described by Bruce ''et al.'' in 1913.Bruce D., Harvey D., Hamerton A. E. and Bruce (1913) Proc. Royal Soc. Lond. B pp45-50 Description The schizonts give rise to 8-12 merozoites. Mature merozoites measure 10 x 10 micrometres. The merozoites are large measuring 3.5 by 4.0 micrometres. The gametocytes are round and possess a number of darkly staining granules. The infected erythrocytes are pale. Distribution This species was described in Malawi. Hosts The parasite was found in the blood of two antelopes (''Cephalophus grimmi''). It is also known to infect the grey duiker (''Sylvicapra grimmia The common duiker (''Sylvicapra grimmia''), also known as the grey or bush duiker, is a small antelope and the mono ...

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] |
Vinckeia
''Vinckeia'' is a subgenus of the genus ''Plasmodium'' — all of which are parasitic alveolates. The subgenus ''Vinckeia'' was created by Cyril Garnham in 1964 to accommodate the mammalian parasites other than those infecting the primates. Diagnostic features Species in this subgenus infect mammals other than the higher primates. Species infecting lemurs have since been included in this subgenus. This classification may not be correct. Schizonts: These do not fill the erythrocyte and do not show true stippling. They give rise normally to 8 or fewer merozoites. Schizogony normally takes three days or less. Merozoites: Gametocytes: These are spherical. Species in this subgenus The following is a list of species in subgenus ''Vinckeia'' and their hosts. *''Plasmodium achromaticum'' — insectivorous bat species *''Plasmodium aegyptensis'' — African grass rat (''Arvicanthis niloticus'') *''Plasmodium anomaluri'' — African flying squirrel ('' Anomalurus'' species) * ...

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] |
Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Duiker
A duiker is a small to medium-sized brown antelope native to sub-Saharan Africa, found in heavily wooded areas. The 22 extant species, including three sometimes considered to be subspecies of the other species, form the subfamily Cephalophinae or the tribe Cephalophini. Taxonomy and phylogeny The tribe Cephalophini (formerly the subfamily Cephalophinae) comprises three genera and 22 species, three of which are sometimes considered to be subspecies of the other species. The three genera include ''Cephalophus'' (15 species and three disputed taxa), ''Philantomba'' (three species), and ''Sylvicapra'' (one species). The subfamily was first described by British zoologist John Edward Gray in 1871 in ''Proceedings of the Zoological Society of London''. The scientific name "Cephalophinae" probably comes from the combination of the New Latin word ''cephal'', meaning head, and the Greek word ''lophos'', meaning crest. The three disputed species in ''Cephalophus'' are Brooke's dui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sylvicapra Grimmia
The common duiker (''Sylvicapra grimmia''), also known as the grey or bush duiker, is a small antelope and the monotypic taxon, only member of the genus ''Sylvicapra''. This species is found everywhere in Africa south of the Sahara, excluding the Horn of Africa and the rainforests of the central and western parts of the continent. Generally, they are found in habitats with sufficient vegetation cover to allow them to hide—savanna and hilly areas, including the fringes of human settlements. Description Colouration of this species varies widely over its vast geographic range. There are 14 subspecies described, ranging from chestnut in forested areas of Angola to grizzled gray in northern savannas and light brown shades in arid regions. It grows to about in height and generally weighs ; although females are generally larger and heavier than the males. Only the male has horns and these can grow to long. Behavior Breeding is year round and the female gives birth to one fawn after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
