is mad cow disease caused by a bacteria?transmissible spongioform enchephalopathies (tse's), include bovine spongiform encephalopathy (also called bse or "mad cow disease"), creutzfeldt-jakob disease (cjd) in humans, and scrapie in sheep. they remain a mystery, their cause hotly debated. but between 1994 and 1996, 12 people in england came down with cjd, the human form of mad cow, and all had eaten beef from suspect cows. current mad cow diagnosis lies solely in the detection of late appearing "prions", an acronym for hypothesized, ge ...200415325025
breeding programmes for tse resistance in british sheep. i. assessing the impact on prion protein (prp) genotype frequencies.from april 2005, member states of the european union were required to implement a compulsory breeding programme for resistance to transmissible spongiform encephalopathies (tses) in sheep as part of measures to eradicate tses from national flocks. in this paper, we assessed the impact of four different breeding strategies on prion protein (prp) genotype frequencies using a mathematical model which describes in detail gene flow in the british sheep flock. these strategies ranged from the minimum ...200616169614
