The second case involved a known recipient of such cells transfused from another asymptomatic donor who subsequently died from variant CJD, whereas the recipient showed no evidence of neurological disease and died of unrelated causes. However, abnormal prion protein was detected in the recipient’s lymphoid tissues, indicating transmission of infection from an asymptomatic individual.
第二起病例涉及一位已知的红细胞接受者，他输入了另一位无任何症状的献血者的血液，这位捐献者后来死于变异型克雅氏病，而受血者却没有神经疾病的任何症状，最后死于其它不相关的疾病。但在受血者的淋巴组织中却查出了异常的朊蛋白，这表明没有任何症状的个体也具备传染能力。
