虽然导致朊病毒疾病的感染原的确切结构还不清楚，但其分子遗传学重要特征已被阐明。从疯牛病到人的传染力强烈表明需要充分理解并重视朊病毒生物学。可传播亚急性海绵状脑病（ThEs）——包括羊瘙痒病，牛海绵状脑病（BSE），克-雅氏病（QJD）在内的研究充满了困难。致病的传播 Although the exact structure of the infectious agent causing the prion disease is not yet known, its important molecular genetic characteristics have been elucidated. From mad cow disease to human infectivity strongly suggests the need to fully understand and pay attention to prion biology. Transmissible subacute spongiform encephalopathy (ThEs) - including scrapie, bovine spongiform encephalopathy (BSE), Creutzfeldt-Jakob disease (QJD), is fraught with difficulties. Pathogenic spread
