CABGED ENCEPHALOPATHY CATTLE
CABGED ENTEPHALOPATHY CATTLE - a zoonotic slow infection characterized by lesion of the cells of the gray matter of the brain. It refers to prion diseases. Prion is a low molecular weight protein with infectious properties. It passes through bacterial filters, is not cultivated on nutrient media, is destroyed by the action of phenol and ether, when heated to 80 ° C.
The source of infectious agents is cattle, among which there are epidemics (England) and sporadic cases; other animals are sick, such as cats. A sick person is not contagious. Infection occurs when infected brains, meat, internal organs of cattle, which have not undergone sufficient heat treatment, are consumed. It is possible that the pathogen may enter through the microtrauma of the skin and mucous membranes when cooking from infected meat, cutting carcasses of infected animals. Human susceptibility has not been studied, it is believed that the disease develops only in genetically predisposed persons.
The incubation period is from 5 to 35 years. The disease is characterized by increasing weakness, dementia, impaired motor functions, leading to death after 6-12 months. Effective treatment methods are not developed.
Prevention is reduced to the abandonment of eating meat and meat products of animals from disadvantaged areas, the observance of the rules of personal hygiene and safety in the care of animals and contact with meat (wearing overalls, the use of gloves).
