Enzootic Bovine Leukosis
EBL is a chronic disease of cattle caused by the retrovirus, bovine leukaemia virus (BLV). The disease is transmitted either directly by transmission of lymphocytes via blood, semen or milk or indirectly via insects. The disease does not spread rapidly, but in infected herds the number of seropositive animals may be 80%.
The disease occurs worldwide, its prevalence varies from country to country.
Clinical signs of EBL appear in a small proportion of infected animals and are usually apparent in cattle between 4 and 8 years of age and only rarely seen in animals under 2 years old. Clinical signs are loss of body condition, persistent lymphocytosis and swelling of the spleen and liver. Diseases of the immune complex may occur later and only 1 to 10% of infected animals develop lymphatic sarcoma. Clinically affected animals will lose condition and eventually die.
As with other retrovirus infections, infected animals remain infected for life. BLV has serious implications for animal health and welfare. In many countries EBL is a notifiable disease.
Prionics offers a highly reliable ELISA for the diagnosis of BLV in bovine milk and serum samples. The tests are produced by Ingenasa.
