Plasmodium Odocoilei
''Plasmodium odocoilei'' is a species of parasites, that causes malaria in white-tailed deer. Taxonomy This species was discovered in 1967 in Texas and formally named in 1980. It was rediscovered again in North America in 2016. This species is a member of the subgenus ''Vinckeia'' of the genus ''Plasmodium''. The genus ''Plasmodium'' is most closely related to ''Polychromophilus''. The relation between these genera is under debate at present and a revision of the taxonomy seems likely to be required. From this study it seems that ''Plasmodium odocoilei'' belongs to a clade that is most closely related to ''Polychromophilus''. This study was based on mitochondria, plastid and nuclear genes which makes it likely to have the correct topology. Molecular genetic studies have show that this species is actually at least two separate species that diverged between to . Description This species has large vacuoles in the erythroctic stages. It causes deformation and discolouration of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted parasitism, parasitoidism, and micropreda ...

Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...

White-tailed Deer
The white-tailed deer (''Odocoileus virginianus''), also known as the whitetail or Virginia deer, is a medium-sized deer native to North America, Central America, and South America as far south as Peru and Bolivia. It has also been introduced to New Zealand, all the Greater Antilles in the Caribbean (Cuba, Jamaica Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of His ..., Hispaniola, and Puerto Rico), and some countries in Europe, such as the Czech Republic, Finland, France, Germany, Romania and Serbia. In the Americas, it is the most widely distributed wild ungulate. In North America, the species is widely distributed east of the Rocky Mountains as well as in southwestern Arizona and most of Mexico, except Baja California peninsula, Lower California. It is mostly displaced by the black ... [...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) *''Pl ...

Polychromophilus
The genus ''Polychromophilus'' consists of obligate intracellular eukaryotic Parasitism, parasites that infect bats from every continent except Antarctica. They are transmitted by bat flies, which act as an insect vector as well as the parasite’s site of Apicomplexan life cycle, sporogeny. ''Polychromophilus'' follows a fairly typical Haemosporida, Haemospororidian lifecycle, with gametocytes and gametes restricted to the bloodstream of the host and meronts infecting organs – most notably the lungs and the liver. The type species is ''Polychromophilus melanipherus'', and was described by Dionisi in 1898. Taxonomy ''Polychromophilus'' was first described by Dionisi in 1898, who also differentiated between the first two species, ''Polychromophilus murinus'' and ''Polychromophilus melanipherus''. Both of these original species were named after their primary hosts – ''Vespertilio murinus'' and ''Miniopterus schreibersi'' respectively. In 1906, Schingareff managed to observe and ...

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.
