Enzootic bovine leukosis is a highly infectious disease caused by a deltaretrovirus of the retroviridae family, which affects bovines of all ages and that generates a high economic impact leucosis viral bovina the dairy herds.

Rabbits get a fatal AIDS like disease similar to rabbit-snufflesdifferent from the benign human snuffles. BLV infection in humans can be identified by testing for antibodies against BLV using the immunoblotting and searching for antibodies against the purified recombinant p24 capsid leucosis viral bovina. For other viral leucosis, see Leucosis.

Transmission through procedures that transmit blood leucosis viral bovina animals such as gouge dehorning, virall and ear tagging with instruments or needles that are not changed or disinfected between animals is a significant means of BLV spread. The natural host of BLV is cattle. Only some leucosis viral bovina later develop a B-cell leukemia called enzootic bovine leukosis.

No se encontraron casos de linfosarcoma ni de linfoma maligno en el estudio. While transmission has been documented via blood feeding insects, the significance of this risk is unclear.
