A serological study was undertaken to determine the prevalence of bovine leukaemia virus (BLV) infection in dairy and beef cattle in Florida. Using the agar gel immunodiffusion test with a glycoprotein antigen, 47.8% of 7768 dairy cattle and 6.7% of 4911 beef cattle were found to have antibodies to BLV. The prevalence of BLV antibodies increased significantly with increasing age. After data were adjusted for age, prevalence of BLV antibodies was significantly associated with dairy breed but not with species (Bos taurus and B. indicus) or sex.
