凡能致癌瘤的病毒统称肿瘤病毒 (ｏｎｃｏｖｉｒｕｓ)包括ＤＮＡ肿瘤病毒和ＲＮＡ肿瘤病毒。 190 8年Ｅｌｌｅｒｍａｎｎ和Ｂａｎｇ首先证明患白血病鸡的无细胞滤液可诱发健康鸡患白血病 ,开创了病毒致癌的实验研究。经 80多年肿瘤病毒病因的研究 ,已发现在 6 0 0多种动物病毒
Viruses that can cause carcinomas are collectively referred to as oncoviruses, including DNA tumor viruses and RNA tumor viruses. In 1908, Ellermann and Bang first demonstrated that a cell-free filtrate from leukemia chickens can induce leukemia in healthy chickens, opening up an experimental study on the carcinogenesis of viruses. After more than 80 years of research on the cause of cancer virus, more than 600 kinds of animal viruses have been found
