Generally, once infected, treatment options are limited. [4] Injecting the lesion with cidofovir or applying imiquimod has been studied. [4] However, it is sometimes required to excise the pustules.. [4] The vaccine used in sheep to prevent orf is live and has been known to cause disease in humans. [4] The disease is endemic in livestock herds ...
Nutritional Muscular Dystrophy (Nutritional Myopathy or White Muscle Disease) is a disease caused by a deficiency of selenium and vitamin E in dietary intake. [1] Soils that contains low levels of selenium produce forages and grains that are deficient in selenium.
foot-and-mouth disease; mastitis; Nairobi sheep disease orthonairovirus (NSDV) infection; orf, also known as contagious ecthyma, contagious pustular dermatitis, infectious labial dermatitis, thistle disease, sore mouth, or scabby mouth; ovine encephalomyelitis (louping ill) ovine progressive pneumonia (OPP) ovine pulmonary adenocarcinoma
The duration of the disease can vary from a few weeks to many months or even years. In the first stage of the disease, bacteremia occurs and leads to the classic triad of undulant fevers, sweating (often with a characteristic foul, moldy smell sometimes likened to wet hay), and migratory arthralgia and myalgia (joint and muscle pain).

Scrapie and other transmissible spongiform encephalopathies are caused by prions. [19] Prions were determined to be the infectious agent because transmission is difficult to prevent with heat, radiation and disinfectants, the agent does not evoke any detectable immune response, and it has a long incubation period of between 18 months and 5 years.

When infection begins, the animal may develop a fever, and the affected limb can feel hot to the touch. The limb usually swells significantly, and the animal can develop lameness on the affected leg. Crepitation (the sensation of air under the skin) can be noticed in many infections, as the area seems to crackle under pressure. [8]
During the initial infection, invasion of the intestines can result in diarrhea, abdominal pain, and vomiting. [1] Migration of larvae to muscle, which occurs about a week after being infected, can cause swelling of the face, inflammation of the whites of the eyes, fever, muscle pains, and a rash. [1] Minor infection may be without symptoms. [1]
CVV disease is a neuroinvasive illness. [16] Of the three confirmed human cases of CVV disease two resulted in non-fatal meningitis, only the first case caused fatal encephalitis and multiorgan failure. The first case was a 28-year-old man from North Carolina in 1995. It is likely he was infected with the virus via mosquitos during a deer ...
