Plasmodium Brasilianum
''Plasmodium brasilianum'' is a parasite that infects many species of platyrrhine monkeys in South and Central America. Description Sequence analysis of circumsporozoite protein, merozoite surface protein-1, and small subunit ribosomal RNA of ''P. malariae'' and ''P. brasilianum'' showed that the two parasites were very closely related. It is considered plausible that ''P. brasilianum'' in platyrrhines is a result of the cross-species transfer of '' P. malariae'' brought to the New World by settlers in the post-Columbus era. As ''P. malariae'' and ''P. brasilianum'' have now been demonstrated to be genetically identical based on 18S rRNA sequences, it has been proposed that ''P. brasilianum'' be subsumed under the name ''P. malariae''. Distribution ''Plasmodium brasilianum'' naturally infects species of primates from all New World monkey families from a large geographic area in Central and South America. The parasite has been found in Panama, Venezuela, Colombia, Peru, Brazil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasmodium Malariae
''Plasmodium malariae'' is a parasitic protozoan that causes malaria in humans. It is one of several species of ''Plasmodium'' parasites that infect other organisms as pathogens, also including ''Plasmodium falciparum'' and ''Plasmodium vivax'', responsible for most malarial infection. Found worldwide, it causes a so-called "benign malaria", not nearly as dangerous as that produced by ''P. falciparum'' or ''P. vivax''. The signs include fevers that recur at approximately three-day intervals – a ''quartan fever'' or ''quartan malaria'' – longer than the two-day (tertian) intervals of the other malarial parasites. History Malaria has been recognized since the Greek and Roman civilizations over 2,000 years ago, with different patterns of fever described by the early Greeks. In 1880, Alphonse Laveran discovered that the causative agent of malaria is a parasite. Detailed work of Golgi in 1886 demonstrated that in some patients there was a relationship between the 72-hour life c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Guiana
French Guiana ( or ; french: link=no, Guyane ; gcr, label=French Guianese Creole, Lagwiyann ) is an overseas departments and regions of France, overseas department/region and single territorial collectivity of France on the northern Atlantic Ocean, Atlantic coast of South America in the Guianas. It borders Brazil to the east and south and Suriname to the west. With a land area of , French Guiana is the second-largest Regions of France, region of France (more than one-seventh the size of Metropolitan France) and the largest Special member state territories and the European Union, outermost region within the European Union. It has a very low population density, with only . (Its population is less than that of Metropolitan France.) Half of its 294,436 inhabitants in 2022 lived in the metropolitan area of Cayenne, its Prefectures in France, capital. 98.9% of the land territory of French Guiana is covered by forests, a large part of which is Old-growth forest, primeval Tropical r ...

Tamarin
The tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus ''Saguinus''. They are the first offshoot in the Callitrichidae tree, and therefore are the sister group of a clade formed by the lion tamarins, Goeldi's monkeys and marmosets. Taxonomy and evolutionary history Hershkovitz (1977) recognised ten species in the genus ''Saguinus'', further divided into 33 morphotypes based on facial pelage. A later classification into two clades was based on variations in dental measurements. A taxonomic review (Rylands et al., 2016) showed the tamarins are a sister group to all other callitrichids, branching off 15–13 million years ago. Within this clade, six species groups are historically recognised, ''nigricollis'', ''mystax'', ''midas'', ''inustus'', ''bicolor'' and ''oedipus'', five of which were shown to be valid with ''Sanguinus inustus'' placed within the ''midas'' group. The review noted that the smaller-bodied ''nigricollis'' group began dive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marmoset
The marmosets (), also known as zaris or sagoin, are 22 New World monkey species of the genera ''Callithrix'', ''Cebuella'', ''Callibella'', and ''Mico''. All four genera are part of the biological family Callitrichidae. The term "marmoset" is also used in reference to Goeldi's marmoset, ''Callimico goeldii'', which is closely related. Most marmosets are about long. Relative to other monkeys, they show some apparently primitive features; they have claws rather than nails, and tactile hairs on their wrists. They lack wisdom teeth, and their brain layout seems to be relatively primitive. Their body temperature is unusually variable, changing by up to 4°C (7°F) in a day. Marmosets are native to South America and have been found in Bolivia, Brazil, Colombia, Ecuador, Paraguay, and Peru. They have also been occasionally spotted in Central America and southern Mexico. They are sometimes kept as pets, though they have specific dietary and habitat needs that require consideration. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callithrix
''Callithrix'' is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus contains the Atlantic Forest marmosets. The name ''Callithrix'' is derived from the Greek words ''kallos'', meaning beautiful, and ''thrix'', meaning hair. Taxonomy The genera ''Mico'' and ''Callibella'' were formerly considered a subgenus of the genus ''Callithrix''. ''Callithrix'' differs from ''Mico'' in dental morphology and geographic distribution; ''Callithrix'' species are distributed near the Atlantic coast of Brazil, while ''Mico'' species are distributed further inland. ''Callithrix'' differs from ''Callibella'' in these features, as well as in size, with ''Callithrix'' species being significantly larger. ''Callithrix'' species differ from the tamarins of the genus ''Saguinus'' in that ''Callithrix'' has enlarged mandibular incisor teeth the same size as the canine teeth, which are used for gouging holes in trees to extract exudates. ...

Leontopithecus
The four species of lion tamarins or maned marmosets make up the genus ''Leontopithecus''. They are small New World monkeys named for the mane surrounding their face, similar to the mane of a lion. Description Living in the eastern rainforests of Brazil, like all other callitrichids they are arboreal. Lion tamarins weigh up to and are about long, with tails about long. They jump through trees using their fingers to hold on to branches; they use their claws to dig under the bark to search for insects to eat. They also eat some snakes, small lizards, and small fruits. All are endangered or critically endangered, in part because their habitat has been severely disrupted by human development and climate change. Lion tamarins tend to live in family groups, with both parents sharing different tasks of rearing the yearly twins born to them. The mother nurses her young every two to three hours, and the father carries the babies on his back. Diurnal tree-dwellers, they sleep in tr ...

Mico (genus)
''Mico'' is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus was formerly considered a subgenus of the genus ''Callithrix''. Taxonomy ''Mico'' differs from ''Callithrix'' in dental morphology, genetics and geographic distribution: ''Callithrix'' species are distributed in eastern Brazil (mainly the Atlantic Forest), while ''Mico'' species are distributed in the Amazon south of Rio Madeira, though a single species, the black-tailed marmoset, also occurs in the Pantanal and Chaco. Roosmalens' dwarf marmoset (''Mico humilis'') was briefly considered to be a member of a new monotypic genus, ''Callibella'', due mainly to differences in size, genetics, and its bearing of a single young rather than the two that marmosets usually bear. Roosmalens' dwarf marmoset is significantly smaller than the ''Mico'' species, being about midway between the typical ''Mico'' species and the pygmy marmoset, ''Cebuella pygmaea''. ''Mico' ...

Atlantic Forest
The Atlantic Forest ( pt, Mata Atlântica) is a South American forest that extends along the Atlantic coast of Brazil from Rio Grande do Norte state in the northeast to Rio Grande do Sul state in the south and inland as far as Paraguay and the Misiones Province of Argentina, where the region is known as Selva Misionera. The Atlantic Forest has ecoregions within the following biome categories: seasonal moist and dry broad-leaf tropical forests, tropical and subtropical grasslands, savannas, and shrublands, and mangrove forests. The Atlantic Forest is characterized by a high biodiversity and endemism. It was the first environment that the Portuguese colonists encountered over 500 years ago, when it was thought to have had an area of , and stretching an unknown distance inland, making it, back then, the second largest rainforest on the planet, only behind the Amazon rainforest. Over 85% of the original area has been deforested, threatening many plant and animal species with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anopheles Freeborni
''Anopheles freeborni'', commonly known as the western malaria mosquito, is a species of mosquito in the family Culicidae. It is typically found in the western United States and Canada. Adults are brown to black, with yellow-brown hairs and gray-brown stripes on the thorax. Their scaly wings have four dark spots, which are less distinct in the male. Male ''Anopheles freeborni'' aggregate into swarms to attract potential mates. Females are able to overwinter, allowing for seasonal development of eggs in the spring. The western malaria mosquito feeds on bloodmeals. Within the United States’ regions of semiarid or arid climate, it has been historically identified as the primary transmission vector for malaria. It was most notably involved in the malaria outbreaks of northern California during the turn of the 20th century. Description Adult ''A. freeborni'' are medium-sized with overall brown to black coloration. They possess a dark proboscis as well as palpi of similar lengt ...

List Of Plasmodium Species Infecting Primates
The ''Plasmodium'' species infecting primates include the parasites causing malaria in humans. Species infecting humans Common infections *'' Plasmodium falciparum'' (the cause of malignant tertian malaria) *''Plasmodium vivax'' (the most frequent cause of benign tertian malaria) *''Plasmodium ovale curtisi'' (another, less frequent, cause of benign tertian malaria) *''Plasmodium ovale wallikeri'' (another, less frequent, cause of benign tertian malaria) *''Plasmodium malariae'' (the cause of benign quartan malaria) *''Plasmodium knowlesi'' (the cause of severe quotidian malaria in Southeast Asia) Rare cases While infection of humans by other species is known, they are quite rare, in some instances, only a single case. In a number of the cases, the means of infection is unknown, and may be due to accident, i.e. infection by laboratory equipment or a bite by an animal. With the use of the polymerase chain reaction additional species have been and are still being identifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
