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 dig 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 virtually of the United Kingdom, with very serious economic consequences (Moore, 1996).         bovine spongiform encephalitis in the beginning occurs in adult cattle of both male and sissified genders. The most leafy ve rileable age at which cows may 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 many distinct symptoms: changes in mental state mad-cow, abnormalities of posture, movement, and sensation (Hunter, 1993). The aloofness of the clinical disease varies with each case, but most ordinarily lasts for several weeks. BSE continues to progress and is usually considered fatal (Blowey, 1991).          later on extensive research, the pathology of BSE was finally determined. Microscopic lesions in the immemorial 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 oftentimes familiar scrapie family.

Without further investigation, the conclusi on was made 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 charge? Studies showed that the mode of infection was meat and bone meal... If you want to draw a full essay, order it on our website: OrderCustomPaper.com
