About Disease

Enzootic bovine leukosis (EBL) is a disease of cattle caused by BLV, a member of the family Retroviridae. Cattle may be infected at any age, including the embryonic stage. The virus resides in blood lymphocytes where circulating antibodies are unable to neutralize it. Therefore, once an animal is infected with BLV, it is infected for life. BLV is economically significant to the producer because of premature culling or death as a result of lymphosarcoma.

Infection with BLV in cattle gives rise to a persistent antibody response. Antibodies can first be detected 3-16 weeks after infection. They are present in both serum and milk. Maternally derived antibodies may take up to 6 or 7 months to disappear. The antibodies most readily detected are those directed towards the envelope glycoprotein gp51 of the virus.
