Use of a DNA probe in the diagnosis of enzootic bovine leukemia.

The authors describe the possibility of adopting a DNA probe in the detection of Bovine Leukemia Virus (BLV), using the molecular hybridization technique. The study was carried out on 18 seropositive Friesian cows taken from different stock farms during the persistent lymphocytosis phase. The presence of a possible BLV molecular variant was highlighted in one stock farm.
