Braxy
Braxy is an infectious disease which causes sudden death in sheep. It is caused by the bacterium '' Clostridium septicum''. Braxy generally occurs in winter, when sheep eat frosted root crops, or frosted grass. The frozen feed damages the mucosa (lining) of the abomasum, allowing ''C. septicum'' to enter, causing abomasitis and a fatal bacteremia.

There is no treatment, and sheep usually die within 36 hours of the onset of signs. The carcass of sheep which died of braxy will often decompose more rapidly than expected. Historically, the mutton of affected sheep was also referred to as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clostridium Septicum
''Clostridium septicum'' is a gram positive, spore forming, obligate anaerobic bacterium. ''Clostridium septicum'' can cause gas gangrene, but unlike other Clostridium species like ''Clostridium perfringens'', no trauma is necessary at the site of the infection. It is thought that the infection is established by hematogenous spread from the gastrointestinal tract. Gas gangrene caused by ''Clostridium septicum'' is associated with colorectal cancer and other defects of the bowel. ''Clostridium septicum'' causes myonecrosis through the release of exotoxins such as the alpha toxin, lethal toxin, and hemolytic toxin General and morphological information ''Clostridium septicum'' is a large, gram-positive, rod-shaped bacterium that is a member of the normal gut flora in humans as well as other animals. ''C. septicum'' are spore formers, with a terminal spore that gives them their drumstick-like shape. They are also motile bacteria, using peritrichous flagellae to navigate fr ...

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 (biology), 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 sheep milk, milk. A sheep's wool is the most widely used animal fiber, and is usually harvest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacterium
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacteremia
Bloodstream infections (BSIs), which include bacteremias when the infections are bacterial and fungemias when the infections are fungal, are infections present in the blood. Blood is normally a sterile environment, so the detection of microbes in the blood (most commonly accomplished by blood cultures) is always abnormal. A bloodstream infection is different from sepsis, which is the host response to bacteria. Bacteria can enter the bloodstream as a severe complication of infections (like pneumonia or meningitis), during surgery (especially when involving mucous membranes such as the gastrointestinal tract), or due to catheters and other foreign bodies entering the arteries or veins (including during intravenous drug abuse). Transient bacteremia can result after dental procedures or brushing of teeth. Bacteremia can have several important health consequences. The immune response to the bacteria can cause sepsis and septic shock, which has a high mortality rate. Bacteria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaccine
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease. The safety and effectiveness of vaccines has been widely studied and verified. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylactic (to pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutton
Lamb, hogget, and mutton, generically sheep meat, are the meat of domestic sheep, ''Ovis aries''. A sheep in its first year is a lamb and its meat is also lamb. The meat from sheep in their second year is hogget. Older sheep meat is mutton. Generally, "hogget" and "sheep meat" are not used by consumers outside Norway, New Zealand, South Africa, Scotland and Australia. Hogget has become more common in England, particularly in the North (Lancashire and Yorkshire) often in association with rare breed and organic farming. In South Asian and Caribbean cuisine, "mutton" often means goat meat.''Oxford English Dictionary'', 3rd edition, June 2003Italian_language.html" ;"title="Spanish language">Spanish, Italian language">Italian and Arabic, make similar or even more detailed distinctions among sheep meats by age and sometimes by sex and diet—for example, ''lechazo'' in Spanish refers to meat from milk-fed (unweaned) lambs.

Moredun Research Institute
The Moredun Research Institute is a scientific research institution based at the Pentlands Science Park, in the Bush Estate area of Midlothian, Scotland. It conducts research into diseases of farm livestock and the promotion of animal health and welfare. Moredun employs over 200 vets, scientists and support staff, that are funded primarily by the Agriculture, Food and Rural Communities Directorate of the Scottish Government. The Institute received £7.1 million from the government in 2010–11. the Scottish Government History The Animal Diseases Research Association, now the registered charity the Moredun Foundation, was founded in 1920 by a group of Scottish farmers, with the aim of improving the health of livestock, especially |
