Epidemiologic association between virus-negative feline leukemia and the horizontally transmitted feline leukemia virus.
About two-thirds of the natural cases of feline leukemia-lymphoma are assumed to be caused by the feline leukemia virus (FeLV) because they occur in cats, which harbor this agent, and FeLV will induce the disease under laboratory conditions. Epidemiological evidence is presented which associates cases of naturally occurring 'virus negative' feline leukemia with exposure to FeLV.
