Viral Causation of Animal LymphomaA REMARKABLY coherent view of the etiology of animal lymphoma and lymphoid leukemia has emerged in the decade since human lymphoma was last reviewed in the New England Journal of Medicine.¹ Lymphomas and lymphoid leukemias are prominent disorders in most animal species subject to close medical scrutiny. Over the past 10 years evidence has accumulated that these neoplasms of lower forms are almost universally of viral causation. Thus, the evidence is conclusive that lymphoid leukemias and lymphomas of mice, rats, chickens and cats are caused by oncogenic viruses (usually RNA viruses with C-type morphology), and . . .
