Akabane Virus
Akabane virus is an insect-transmitted virus that causes congenital abnormalities of the central nervous systems in ruminants. The virus is found in Australia, where it is most commonly spread by biting midges of the '' Culicoides'' species. Disease Malformation of the joints, brain, spine and jaw are common in affected newborn animals. Abortion may also occur if damage to the fetus is severe.Akabane Virus reviewed and published by WikiVet, accessed 10 October 2011. Diagnosis and treatment Viral isolation can be attempted with immunofluorescence or[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission Electron Micrograph
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and Focus (optics), focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a Detectors for transmission electron microscopy, detector such as a scintillator attached to a charge-coupled device or a direct electron detector. Transmission electron microscopes are capable of imaging at a significantly higher Optical resolution, resolution than Optical microscope, light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arbovirus
Arbovirus is an informal name for any virus that is Transmission (medicine), transmitted by arthropod Vector (epidemiology), vectors. The term ''arbovirus'' is a portmanteau word (''ar''thropod-''bo''rne ''virus''). ''Tibovirus'' (''ti''ck-''bo''rne ''virus'') is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals (including humans) and plants. In humans, symptoms of arbovirus infection generally occur 3–15 days after exposure to the virus and last three or four days. The most common clinical features of infection are fever, headache, and malaise, but encephalitis and viral hemorrhagic fever may also occur. Signs and symptoms The incubation period – the time between when infection occurs and when symptoms appear – varies from virus to virus, but is usually limited between 2 and 15 days for arboviruses. The majority of infections, however, are asymptomatic. Among cases in which sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruminant
Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.

Culicoides
''Culicoides'' is a genus of biting midges in the family Ceratopogonidae. There are over 1000 species in the genus,Connelly, C. RBiting midges: ''Culicoides'' spp.Featured Creatures, Entomology and Nematology Department, University of Florida IFAS. August 2013 Edition. which is divided into many subgenera. Several species are known to be vectors of various diseases and parasites which can affect animals. The genus has a long fossil record, with earliest known fossils being from Burmese amber, around 99 million years old. Notable taxa The systematics and taxonomy of this genus are confused. A large number of species are of unknown relation to those that have been assigned to subgenera already. Furthermore, many subgenera are sometimes elevated to full genus status, or additional genera (such as '' Paradasyhelea'') are included as subgenera herein. A widely cited, periodically updated, subgeneric classification of species of ''Culicoides'' begins with the warning that the traditi ...

WikiVet
WikiVet is a wiki of veterinary content based on the MediaWiki platform. The website is a collaborative initiative between various veterinary schools, and its content covers the entire veterinary curriculum. WikiVet is part of the WikiVet Educational Foundation (UK registered charity number 1160546). Full access to WikiVet requires a free registration, which is available to veterinarians, veterinary students and veterinary technicians. Except for content relating specifically to the veterinary curriculum, articles are authored by students or veterinarians, and subsequently peer reviewed by subject specialists. History WikiVet was established in 2007 to provide online access to a comprehensive veterinary undergraduate curriculum. The consortium was initially formed by three UK veterinary schools, London's Royal Veterinary College, the University of Edinburgh's Royal (Dick) School of Veterinary Studies, and the University of Cambridge's Department of Veterinary Medicine, and was s ...

Immunofluorescence
Immunofluorescence (IF) is a light microscopy-based technique that allows detection and localization of a wide variety of target biomolecules within a cell or tissue at a quantitative level. The technique utilizes the binding specificity of antibodies and antigens. The specific region an antibody recognizes on an antigen is called an epitope. Several antibodies can recognize the same epitope but differ in their binding affinity. The antibody with the higher affinity for a specific epitope will surpass antibodies with a lower affinity for the same epitope. By conjugating the antibody to a fluorophore, the position of the target biomolecule is visualized by exciting the fluorophore and measuring the emission of light in a specific predefined wavelength using a fluorescence microscope. It is imperative that the binding of the fluorophore to the antibody itself does not interfere with the immunological specificity of the antibody or the binding capacity of its antigen. Immunofluore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymerase Chain Reaction
The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study. PCR was invented in 1983 by American biochemist Kary Mullis at Cetus Corporation. Mullis and biochemist Michael Smith (chemist), Michael Smith, who had developed other essential ways of manipulating DNA, were jointly awarded the Nobel Prize in Chemistry in 1993. PCR is fundamental to many of the procedures used in genetic testing and research, including analysis of Ancient DNA, ancient samples of DNA and identification of infectious agents. Using PCR, copies of very small amounts of DNA sequences are exponentially amplified in a series of cycles of temperature changes. PCR is now a common and often indispensable technique used in medical laboratory research for a broad variety of applications including biomedical research and forensic ...

Schmallenberg Virus
Schmallenberg virus, abbreviated SBV, is a virus that causes congenital malformations and stillbirths in cattle, sheep, goats, and possibly alpaca. It appears to be transmitted by midges (''Culicoides'' spp.), which are likely to have been most active in causing the infection in the Northern Hemisphere summer and autumn of 2011, with animals subsequently giving birth from late 2011. Schmallenberg virus falls in the Simbu Serotype, serogroup of orthobunyaviruses. It is considered to be most closely related to the Sathuperi virus, Sathuperi and Douglas virus, Douglas viruses. The virus is named after Schmallenberg, in North Rhine-Westphalia, Germany, from where the first definitive sample was derived. It was first reported in October 2011. After Germany, it has also been detected in the Netherlands, Belgium, France, Luxembourg, Italy, Spain, the United Kingdom, Switzerland, Ireland, Finland, Denmark, Sweden, Austria, Norway, Poland and Estonia. The virus has been recognised by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
