不活跃的“病毒”一种比病毒还小,具有增殖能力与感染力的谜一般的“病原体”,据说它没有基因,目前正在引起全球生物学家与医学科学家的密切注意。事实上,它是本来已有的一种“不活跃病毒”。这种极小的病原体长期留在动物体内引起一种型式异常的病毒病,就是所谓的“慢性病毒感染症”,也有过一段时期排除了认为它是亚急性脊髓视神经症之类的疾病。 Inactive “virus” A mysterious “pathogen” that is smaller than a virus and has proliferative and infectious power. It is said that it has no genes and is now attracting close attention from biologists and medical scientists around the world. In fact, it is already an “inactive virus.” This very small form of a long-term presence in animals causes a type of abnormal virus disease, the so-called “chronic viral infection,” and has for some time ruled out the disease as subacute spinal optic neurosis.
