Bovine Spongiform Encephalopathy, Mad cow disease

        Bovine spongiform encephalopathy (bovine spongiform encephalitis) is a relatively new complaint found to begin with in cattle. This indisposition of the bovine extend 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 malady developed into a large-scale epidemic in near of the United Kingdom, with very serious economic consequences (Moore, 1996).         bovine spongiform encephalitis originally occurs in adult cattle of both male and epicene genders. The most leafy ve rileable age at which cows whitethorn be affected is between the ages of four and five (Blowey, 1991). imputable to the fact that BSE is a neurological disease, it is characterized by many distinct symptoms: changes in mental state mad-cow, abnormalities of posture, movement, and sensation (Hunter, 1993). The distance of the clinical disease varies with each case, but most usually lasts for several weeks. BSE continues to progress and is usually considered fatal (Blowey, 1991).          afterward extensive research, the pathology of BSE was finally determined. Microscopic lesions in the pristine 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 untold reciprocal scrapie family.

Without further investigation, the conclusion was made tha t 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 single 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 black market? Studies showed that the mode of infection was meat and bone meal... If you want to lead off a full essay, order it on our website: OrderCustomPaper.com
