Scrapie. Light micrograph of a section through the brain of a sheep infected with scrapie. Nuclei (black dots) of nerve cells,or neurones,are seen. At centre,large white vacuole spaces show the effect of the disease. As scrapie progresses,increased vacuolation makes the brain tissue spongy and destroys nerve cells. The disease causes symptoms of glazed eyes and body tremors. Scrapie,like the cattle disease BSE (Bovine Spongiform Encephalopathy),is due to a virus-like prion. BSE cattle have been linked to the fatal new variant Creutzfeldt-Jakob disease (vCJD) in humans. Magnification unknown | |
