Technical Abstract: Using standard methods, ADOL-R5-4, a field strain of subgroup J avian leukosis virus (ALV-J) was molecularly cloned. This molecular clone named ALV-J p-R5-4 was propagated and titrated in line 0 chicken-embryo fibroblasts. The pathogenicity of this molecular clone, ALV-J p-R5-4 was tested in meat-type chickens; day-old chicks were each inoculated with 100,000 infectious units of virus at hatch. Inoculated chickens tested positive for ALV-J viremia and developed tumors within 30 weeks of age. Data indicate that the ALV-J pR5-4 is infectious; it is currently being used to determine role of E element in pathogenesis of the disease.
