[Immunoenzyme detection of enzootic bovine leukemia viruses (BLV) in cell cultures].

There is a description of the method of immunoenzymic test used for detection of enzootic bovine leukosis virus (BLV) on the cells of foetal lamb spleen (FLS) permanently producing BLV and on the lymphocytes of infected animals. In both cases (in FLS cells and lymphocytes) the presence of BLV was demonstrated by the immunoperoxidase test. Using the defined serums from the animals after experimental and natural infection, BLV was detected by the above-mentioned test in FLS cells in all cases of the use of positive serums with anti-BLV antibodies.
