WebThe oncogenicity of the avian leukosis viruses (ALV) has been well documented (2,3,9,14). In most reports, the isolates studied were obtained from birds with gross tumors, were from birds from flocks that had experienced a high mortality rate from lymphoid leukosis (LL), or were isolates associated with Rous sarcoma viruses (RSV) (18). crochet motif denim shirtAvian sarcoma leukosis virus (ASLV) is an endogenous retrovirus that infects and can lead to cancer in chickens; experimentally it can infect other species of birds and mammals.
