The diagnosis of enzootic bovine leukosis.
This paper reviews the clinical and virological diagnostic procedures for enzootic bovine leukosis (EBL). The clinical diagnosis must be always confirmed by a specific laboratory test for Bovine Leukaemia Virus (BLV). Many virological tests were proposed. The sensitivity of all the diagnostic methods is sufficient to do an early detection of a BLV infection on an individual base. Advantages of the highly sensitive methods like RIA and ELISA appear when the samples to be tested have naturally very low antibody titers (individual milk, bulk milk, pooled sera).
