Reticuloendotheliosis viruses have been shown to be causative of tumors in a variety of avian species. The major structural protein of these non-genetically transmitted viruses is demonstrated to possess antigenic determinants common to those of all known mammalian type C viruses. These findings establish a mammalian origin for this oncogenic avian retrovirus group. None of the known mammalian type C virus groups demonstrated a closer immunological relationship to avian reticuloendotheliosis viruses. These results suggest that reticuloendotheliosis viruses have been non-genetically transmitted for a long period of evolution or that these viruses may have arisen by relatively recent infection of birds with an as yet undiscovered mammalian type C retrovirus.
网状内皮增生症病毒已被证明可在多种禽类中引发肿瘤。这些非基因传播病毒的主要结构蛋白被证明具有所有已知哺乳动物C型病毒共有的抗原决定簇。这些发现确定了这种致癌性禽逆转录病毒群体的哺乳动物起源。已知的哺乳动物C型病毒群体中,没有一个与禽网状内皮增生症病毒表现出更密切的免疫关系。这些结果表明,网状内皮增生症病毒在长期进化过程中一直通过非基因方式传播,或者这些病毒可能是鸟类最近被一种尚未发现的哺乳动物C型逆转录病毒感染后产生的。
