Bovine leukosis is a disease of cattle caused by the bovine leukosis virus (BLV). This is a blood-borne disease; the virus survives in white blood cells, called lymphocytes. Only about 5% of the cows infected with BLV ever develop a clinical disease. When clinical disease does occur, the primary sign is the development of tumors (lymphosarcoma). Bovine leukemia virus causes a persistent lifelong infection that can progress to multicentric lymphosarcoma (lymphoma) in a small subset of infected adult cattle. Contrary to the name, bovine leukemia virus is the sporadic cause of solid lymphoid tumors in cattle and is generally not associated with leukemia.

Jun 02, · Bovine leukemia virus (BLV) is an oncogenic retrovirus that infects lymphocytes (white blood cells). Proliferation of these virus-infected lymphocytes results in either a persistent lymphocytosis, a benign form of the disease, or neoplastic tumors that invade many different organ systems (referred to as enzootic bovine leucosis or lymphosarcoma). Dec 17, · Enzootic bovine leukosis, also known as bovine leukemia, lymphosarcoma, or malignant lymphoma, is a cancer of adult cattle caused by bovine leukemia virus (BLV).
