Abstract
During the period 1998-2000, 200518 individual bovine blood sera were tested using the immunodiffusion test for detection of antibodies against the bovine leukosis virus in South-eastern Bulgaria. The results showed that this infection was widespread – 17.02% on average (from 2.78% in the region of Haskovo to 33.07% in the region of Burgas). Those data are evidence that enzootic bovine leukosis is an important epidemiological problem in the light of new conditions for the development of cattle breeding. The incidence of enzootic bovine leukosis must be limited and eventually eradicated through strict execution of the national EBL eradication programme.
