ENZOOTIC BOVINE LEUKOSIS IN DAIRY CATTLE IMPORTED FROM URUGUAY
Keywords:
virus, dairy herds, control, antibody, EBL.Abstract
Antibodies to Bovine Leukemia Virus (BLV) were determincd by the agar gel immunodiffusion test in serum samples from dairy cattle imported from Uruguay to Brazil. From 19,774 samples tested during 1992-1997, 3,225 (16.30 %) had antibodies. These results suggest the necessity to import only negative cattle to BLV and to implant control measures in Brazil.
