Bovine Spongiform Encephalopathy, Mad cow disease

        Bovine spongiform encephalopathy (bovine spongiform encephalitis) is a relatively new distemper found to begin with in cattle. This indisposition of the bovine overcompensate was first seen in the United Kingdom in November 1986 by histopathological examination of affected brains (Kimberlin, 1993) . From the first discovery in 1986 to 1990 this unhealthiness developed into a large-scale epidemic in some of the United Kingdom, with very serious economic consequences (Moore, 1996).          mad cow disease chiefly occurs in adult cattle of both male and unmanly genders. The most leafy ve rileable age at which cows may be affected is between the ages of four and five (Blowey, 1991). attributable to the fact that BSE is a neurological disease, it is characterized by umteen distinct symptoms: changes in mental state mad-cow, abnormalities of posture, movement, and sensation (Hunter, 1993). The distance of the clinical disease var ies with each case, but most normally lasts for several weeks. BSE continues to progress and is usually considered fatal (Blowey, 1991).          afterwards extensive research, the pathology of BSE was finally determined. Microscopic lesions in the native nervous system that consist of a bilaterally symmetrical, non-inflammatory vacuolation of neuronal perikarya and grey-matter neuropil was the scientists overall conclusion (Stadthalle, 1993). These lesions are consistent with the diseases of the a lot parking lot scrapie family.

Without further investigation, the conclusion was made that BSE was a new member of the scrapie family (Westgarth, 1994).       Â Â Â Transmission of BSE is rather common ! throughout the cattle industry. After the incubation period of bingle to two years, experimental transmission was found possible by the injection of brain homogenates from clinical cases (Swanson, 1990). This only confirmed that BSE is caused by a scrapie-like infectious agent.         How does the transmission become so readily available among the entire United Kingdom feedlot racetrack? Studies showed that the mode of infection was meat and bone meal... If you want to turn a full essay, order it on our website: OrderEssay.net
