Plasmodium Billcollinsi
''Plasmodium billcollinsi'' is a species of the genus ''Plasmodium'' subgenus ''Laverania''. It is a parasitic protozoan found in chimpanzees in Central Africa. The parasite is named in honour of the malariologist William E. Collins. Taxonomy Both ''P. billcollinsi'' and ''P. billbrayi'' were suggested based on mtDNA and nuclear gene sequences, in addition to having been obtained from chimpanzee samples. ''Plasmodium billcollinsi'' is located at the root between '' P. falciparum'' and '' P. reichenowi''. Distribution Analysis made on 1,261 samples revealed that at least six ''Plasmodium'' species circulate in great apes in Gabon, with ''P. billcollinsi'' being found faecal samples from 791 chimpanzees. Hosts Along with '' P. reichenowi'', '' P. billbrayi'' and '' P. gaboni'', ''P. billcollinsi'' infects with malaria to only chimpanzees. The parasite has been found in at least three subspecies: '' P. t. verus'', '' P. t. troglodytes'', and '' P. t. schweinfurthii''. S ...

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] |
Laverania
''Laverania'' is a subgenus of the parasite genus ''Plasmodium''. Infection with these species results in malaria. The subgenus was first described in 1958. The name was first proposed by Welch in 1897 as a genus name for the group now known as ''Plasmodium'' but for a variety of reasons the genus name ''Plasmodium'' was preferred. __TOC__ Taxonomy The first non-human primate parasites were described by Eduard Reichenow in Cameroon in 1920. He observed three morphologically distinct ''Plasmodium'' parasites in the blood of chimpanzees and gorillas in 1917. These finding were later confirmed by other workers. One species closely resembled ''P. falciparum'' and was thought to be the same species. This species was later renamed ''P. reichenowi''. The other two species — ''P. rhodaini'' and ''P. schwetzi'' — have since been placed in the subgenus ''Plasmodium''. The noticeable differences between ''P. falciparum'' and the other known ''Plasmodium'' species led to the proposa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Chimpanzee
The chimpanzee (''Pan troglodytes''), also known as simply the chimp, is a species of Hominidae, great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan (genus), ''Pan''. Evidence from fossils and DNA sequencing shows that ''Pan'' is a sister taxon to the Human evolution, human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more Robustness (morphology), robust than the bonobo, weighing for males and for females and standing . The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Erle Collins
William Erle "Bill" Collins (9 July 1929 – 28 September 2013) was an American parasitologist. Collins grew up in Lansing, Michigan, where he graduated from high school. He received his B.S. and M.Sc. in entomology from Michigan State University and then completed his Ph.D. in 1954 at Rutgers University in two years. After being drafted into the U.S. Army, he did his military service at the U.S. Army Biological Warfare laboratories at Fort Detrick. While stationed there, he married Janet Johnson in July 1956. After leaving the Army he worked at Rutgers University as an extension entomologist. In 1959 he was employed by the U.S. Public Health Service at the National Institute of Allergy and Infectious Diseases (NIAID) in Columbia, South Carolina. In 1973 the laboratory operation headed by Collins was transferred to the operational control of the Centers for Disease Control (CDC) and the research emphasis changed from monkey malarial parasites in monkeys to human malarial parasite ...

MtDNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from t ...

Plasmodium Billbrayi
''Plasmodium billbrayi'' is a parasite of the genus ''Plasmodium'' subgenus ''Laverania''. ''P. billbrayi'' is phylogenetically very close to ''Plasmodium gaboni'', with both sharing a recent common ancestor. The parasite is named in honour of the distinguished malariologist “Bill” Robert Stow Bray (1923–2008). Taxonomy ''Plasmodium billbrayi'' was first described along with '' Plasmodium billcollinsi'' by Krief ''et al.'' in February 2010, by sequencing the whole ''Plasmodium'' mitochondrial genome in chimpanzees. Distribution This species is found in East Africa. Hosts ''Plasmodium billbrayi'' infects common chimpanzees (''Pan troglodytes'') and Eastern chimpanzee The eastern chimpanzee (''Pan troglodytes schweinfurthii'') is a subspecies of the common chimpanzee. It is native to the Central African Republic, South Sudan, the Democratic Republic of the Congo, Uganda, Rwanda, Burundi, and Tanzania. Taxono ...s (''Pan troglodytes schweinfurthii''). See al ...

Plasmodium Gaboni
''Plasmodium gaboni'' is a parasite of the genus ''Plasmodium'' subgenus ''Laverania''. ''P. gaboni'' was given its name in reference to Gabon, where the parasite was discovered in two wild-borne chimpanzees kept as pets in villages in that country. ''Plasmodium gaboni'' is phylogenetically very close to '' Plasmodium billbrayi''. Taxonomy In 2009, Ollomo et al. published the complete mitochondrial genome of ''Plasmodium gaboni'', which was not yet named at the time. The parasite belongs to the '' P falciparum/ P reichenowi'' lineage. It has been proposed that ''Plasmodium gaboni'' diverged from the ''P falciparum/P reichenowi'' lineage about 21 million years ago, leading to the conclusion that the ancestor of this parasite clade could have been already present in hominid ancestors. ''Plasmodium gaboni'' is 10-fold more diverse than human parasite '' Plasmodium falciparum'', indicating a very recent origin of the latter. ''Plasmodium gaboni'' is similar to both ''Plasmod ...

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 ...

Western Chimpanzee
The western chimpanzee, or West African chimpanzee, (''Pan troglodytes verus'') is a Critically Endangered subspecies of the common chimpanzee. It inhabits western Africa, specifically Côte d'Ivoire, Guinea, Liberia, Mali, Senegal, Ghana, Guinea-Bissau, but has been extirpated in three countries: Benin, Burkina Faso, and Togo. Etymology The taxonomical genus ''Pan'' is derived from the Greek mythology, Greek god of fields, groves, and wooded glens, Pan (mythology), Pan. The species name ''troglodytes'' is Greek for 'cave-dweller', and was coined by Johann Friedrich Blumenbach in his ''Handbuch der Naturgeschichte'' (''Handbook of Natural History'') published in 1779. ''Verus'' is Latin language, Latin for 'true', and was given to this subspecies in 1934 by Ernst Schwarz (zoologist), Ernst Schwarz, who originally named it as ''Pan satyrus verus''. Taxonomy and genetics The western chimpanzee (''P. t. verus'') is a subspecies of the common chimpanzee (''Pan troglodytes''), along w ...

Central Chimpanzee
The central chimpanzee or the tschego (''Pan troglodytes troglodytes'') is a subspecies of chimpanzee closely related to the other great apes such as gorillas, orangutans, and humans. The central chimpanzee can be found in Central Africa, mostly in Gabon, Cameroon, Republic of Congo and the Democratic Republic of Congo. Central chimpanzees are considered highly intelligent apes. They are also highly social living in large groups and follow a male dominant hierarchy. The activity budgets of this chimpanzee subspecies changes depending on if they were in the wild or in sanctuaries. They have been observed using tools, this could be to open nuts or using twigs to gain access to ants and termites. Central chimpanzees have a key role in the ecology of rainforests, they play an important role as seed dispersers. Even though central chimpanzees and western lowland gorillas overlap the environment in which they live in they do not compete for food as their diets are different. Accord ...

Eastern Chimpanzee
The eastern chimpanzee (''Pan troglodytes schweinfurthii'') is a subspecies of the common chimpanzee. It is native to the Central African Republic, South Sudan, the Democratic Republic of the Congo, Uganda, Rwanda, Burundi, and Tanzania. Taxonomy Though it is formally classified as ''P. t. schweinfurthii'', Colin Groves of the Australian National University argues that there is enough variation between the northern and southern populations of this population of chimpanzees to be split into two subspecies instead of one; the northern population as ''P. t. schweinfurthii'' and the southern population as ''P. t. marungensis''. Threats and conservation The 2007 IUCN Red List classified them as Endangered. Although the common chimpanzee is the most abundant and widespread of the non-human great apes, recent declines in East Africa are expected to continue due to hunting and loss of habitat. Because chimpanzees and humans are physiologically very similar, chimpanzees succumb to many d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
