Control of bovine leukemia virus infection in dairy herds by agar gel immunodiffusion test and segregation of reactors.
Canadian cattle intended for export, in future, may have to originate from herds which are serologically negative for bovine leukemia virus, in addition to being negative individually by the agar gel immunodiffusion test as currently required. In this study, agar gel immunodiffusion testing of herds and segregation of reactors were examined. The results demonstrated that bovine leukemia virus infection could be controlled when three groups: 1) bovine leukemia virus-positive, 2) bovine leukemia virus-negative and 3) replacement cattle were maintained at separate locations.
