Bovine spongiform encephalopathy (bovine spongiform encephalitis) is a relatively new unhealthiness found to begin with in cattle. This indisposition of the bovine cut through 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 disorder developed into a large-scale epidemic in close of the United Kingdom, with very serious economic consequences (Moore, 1996).         mad cow disease in the first place occurs in adult cattle of both male and sissified 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 length of the clinical di sease varies with each case, but most common landly lasts for several weeks. BSE continues to progress and is usually considered fatal (Blowey, 1991).         later extensive research, the pathology of BSE was finally determined. Microscopic lesions in the prime nervous system that consist of a bilaterally symmetrical, non-inflammatory vacuolization of neuronal perikarya and grey-matter neuropil was the scientists overall conclusion (Stadthalle, 1993). These lesions are consistent with the diseases of the frequently common scrapie family.
Without further investigation, the conclusion was made that BSE was a new member of the scrapi! e family (Westgarth, 1994). Â Â Â Â Â Â Â Â Transmission of BSE is rather common throughout the cattle industry. After the incubation period of ace 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. Â Â Â Â Â Â Â Â How does the transmission become so readily available among the entire United Kingdom feedlot travel? Studies showed that the mode of infection was meat and bone meal... If you want to force a full essay, order it on our website: OrderCustomPaper.com
