Bovine Spongiform Encephalopathy, Mad cow disease

        Bovine spongiform encephalopathy (bovine spongiform encephalitis) is a relatively new ailment found to begin with in cattle. This indisposition of the bovine cover 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 infirmity developed into a large-scale epidemic in well-nigh of the United Kingdom, with very serious economic consequences (Moore, 1996).         bovine spongiform encephalitis primarily occurs in adult cattle of both male and womanish genders. The most leafy ve rileable age at which cows whitethorn be affected is between the ages of four and five (Blowey, 1991). referable to the fact that BSE is a neurological disease, it is characterized by umpteen distinct symptoms: changes in mental state mad-cow, abnormalities of posture, movement, and sensation (Hunter, 1993). The continuance of the clinic al disease varies with each case, but most usually 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 primeval 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 more greens scrapie family.

Without further investigation, the conclusion was ma de that BSE was a new member of the scrapie ! family (Westgarth, 1994).         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 raceway? Studies showed that the mode of infection was meat and bone meal... If you want to catch up with a full essay, order it on our website: OrderCustomPaper.com
