Nairobi Sheep Disease
The ''Nairobi sheep disease orthonairovirus'' (NSDV), also known as ''Ganjam virus'' is a species in the genus '' Orthonairovirus'' belonging to the Nairobi sheep disease serogroup. NSDV is enzootic, becoming epizootic when denser populations of susceptible animals are exposed to infection. NSDV's known hosts belong to the hard tick family Ixodidae, including ''Rhipicephalus appendiculatus'', and ''Amblyomma variegatum ''Amblyomma variegatum'', commonly known as the tropical bont tick, is a species of tick of the genus ''Amblyomma'' endemic to Africa. It has spread from its centre of origin to several countries, including the Caribbean islands, where it is kno ...'', and afflict sheep and goats naturally. The virus is in the family Nairoviridae and order Bunyavirales. Symptoms Symptoms of an animal infected with NSDV may include fever, reduction in white blood cells, rapid respiration, anorexia, profound depression, diarrhea, drop in body temperature, premature abortio ...

Orthonairovirus
''Orthonairovirus'' is a genus of viruses in the family ''Nairoviridae'' of the order Bunyavirales that include viruses with circular, negative-sense single stranded RNA. It got its name from the Nairobi sheep disease that affects the gastrointestinal tracts of sheep and goats. The vast majority, and perhaps all viruses in this genus are tick-borne viruses that can have human or other vertebrate hosts.Crabtree, Mary B., Rosemary Sang, and Barry R. Miller. "Kupe Virus, a New Virus in the Family Bunyaviridae, Genus Nairovirus, Kenya." Emerging Infectious Diseases 15 (2009): 147–54.

Maasai Mara
Maasai Mara, also sometimes spelled Masai Mara and locally known simply as The Mara, is a large national game reserve in Narok, Kenya, contiguous with the Serengeti National Park in Tanzania. It is named in honor of the Maasai people, the ancestral inhabitants of the area, who migrated to the area from the Nile Basin. Their description of the area when looked at from afar: "Mara" means "spotted" in the local Maasai language, due to the many short bushy trees which dot the landscape. Maasai Mara is one of the most famous and important wildlife conservation and wilderness areas in Africa, world-renowned for its exceptional populations of lion, leopard, cheetah and African bush elephant. It also hosts the Great Migration, which secured it as one of the Seven Natural Wonders of Africa, and as one of the ten Wonders of the World. The Greater Mara ecosystem encompasses areas known as the Maasai Mara National Reserve, the Mara Triangle, and several Maasai Conservancies, including Koiya ...

Bonnet Macaque
The bonnet macaque (''Macaca radiata''), also known as zati,Chambers English Dictionary is a species of macaque endemic to southern India. Its distribution is limited by the Indian Ocean on three sides and the Godavari and Tapti Rivers, along with its related competitor the rhesus macaque in the north. Land use changes in the last few decades have resulted in changes in its distribution boundaries with the rhesus macaque, raising concern for its status in the wild. The bonnet macaque is diurnal, arboreal, and terrestrial. Males have a head-body length of with a tail while females are with a tail. Males weigh and females . It can live up to 35 years in captivity. The bonnet macaque feeds on fruits, nuts, seeds, flowers, invertebrates, and cereals. In southern India, this macaque exists as commensal to humans, feeding on food given by humans and raiding crops and houses. Taxonomy Two subspecies of bonnet macaques have been identified: *''Macaca radiata radiata'', pale-be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colobinae
The Colobinae or leaf-eating monkeys are a subfamily of the Old World monkey family that includes 61 species in 11 genera, including the black-and-white colobus, the large-nosed proboscis monkey, and the gray langurs. Some classifications split the colobine monkeys into two tribes, while others split them into three groups. Both classifications put the three African genera ''Colobus'', '' Piliocolobus'', and '' Procolobus'' in one group; these genera are distinct in that they have stub thumbs (Greek κολοβός ''kolobós'' = "docked"). The various Asian genera are placed into another one or two groups. Analysis of mtDNA confirms the Asian species form two distinct groups, one of langurs and the other of the "odd-nosed" species, but are inconsistent as to the relationships of the gray langurs; some studies suggest that the gray langurs are not closely related to either of these groups, while others place them firmly within the langur group. Characteristics Colobines are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Duiker
The blue duiker (''Philantomba monticola'') is a small antelope found in central, southern and eastern Africa. It is the smallest duiker. The species was first described by Swedish naturalist Carl Peter Thunberg in 1789. 12 subspecies are identified. The blue duiker reaches at the shoulder and weighs . Sexually dimorphic, the females are slightly larger than the males. The dark tail measures slightly above . It has short, spiky horns, around long and hidden in hair tufts. The subspecies show a great degree of variation in their colouration. The blue duiker bears a significant resemblance to Maxwell's duiker. Activity is diurnal (limited to daytime). Secretive and cautious, the blue duiker confines itself to the forest fringes. Territorial, individuals of opposite sexes form pairs and occupy territories, nearly large and marked by preorbital gland secretions. The blue duiker feeds on fallen fruits, foliage, flowers and pieces of bark, provided mainly by the forest canopies i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Reservoir
In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival. A reservoir is usually a living host of a certain species, such as an animal or a plant, inside of which a pathogen survives, often (though not always) without causing disease for the reservoir itself. By some definitions a reservoir may also be an environment external to an organism, such as a volume of contaminated air or water. Because of the enormous variety of infectious microorganisms capable of causing disease, precise definitions for what constitutes a natural reservoir are numerous, various, and often conflicting. The reservoir concept applies only for pathogens capable of infecting more than one host population and only with respect to a defined target popula ...

Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nairobi, Kenya
Nairobi ( ) is the Capital city, capital and largest city of Kenya. The name is derived from the Maasai language, Maasai phrase ''Enkare Nairobi'', which translates to "place of cool waters", a reference to the Nairobi River which flows through the city. The city proper had a population of 4,397,073 in the 2019 census, while the metropolitan area has a projected population in 2022 of 10.8 million. The city is commonly referred to as the Green City in the Sun. Nairobi was founded in 1899 by colonial authorities in British East Africa, as a rail depot on the Uganda#Railroad, Uganda - Rail transport in Kenya, Kenya Railway.Roger S. Greenway, Timothy M. Monsma, ''Cities: missions' new frontier'', (Baker Book House: 1989), p.163. The town quickly grew to replace Mombasa as the capital of Kenya in 1907. After independence in 1963, Nairobi became the capital of the Republic of Kenya. During Kenya's colonial period, the city became a centre for the colony's coffee, tea and sisal indust ...

Bunyavirales
''Bunyavirales'' is an order of segmented negative-strand RNA viruses with mainly tripartite genomes. Member viruses infect arthropods, plants, protozoans, and vertebrates. It is the only order in the class ''Ellioviricetes''. The name ''Bunyavirales'' derives from Bunyamwera, where the original type species ''Bunyamwera orthobunyavirus'' was first discovered. ''Ellioviricetes'' is named in honor of late virologist Richard M. Elliott for his early work on bunyaviruses. Bunyaviruses belong to the fifth group of the Baltimore classification system, which includes viruses with a negative-sense, single-stranded RNA genome. They have an enveloped, spherical virion. Though generally found in arthropods or rodents, certain viruses in this order occasionally infect humans. Some of them also infect plants. In addition, there is a group of bunyaviruses whose replication is restricted to arthropods and is known as insect-specific bunyaviruses. A majority of bunyaviruses are vector-borne ...

Enzootic
Enzootic is the non-human equivalent of endemic and means, in a broad sense, "belonging to" or "native to", "characteristic of", or "prevalent in" a particular geography, race, field, area, or environment; native to an area or scope. It also has two specific meanings: * an organism being "''enzootic''" means native to a place or a specific fauna * in epizoology, an infection is said to be "''enzootic''" in a population when the infection is maintained in the population without the need for external inputs (''cf''. Endemic). See also *Epizootic In epizoology, an epizootic (from Greek: ''epi-'' upon + ''zoon'' animal) is a disease event in a nonhuman animal population analogous to an epidemic in humans. An epizootic may be restricted to a specific locale (an "outbreak"), general (an "epi ... Biodiversity {{Veterinary-med-stub ...
