Bovine and ovine leukemia viruses. I. Characterization of viral antigens.

A comparative study on several virus-specific antigens of bovine and ovine leukemia viruses is presented. In addition to the major immunologically reactive, nonglycosylated antigen p21, which has a molecular weight of 21,000, both viruses share two glycoproteins of apparent molecular weights of 60,000 (gp60) and 32,000 (gp32), respectively. Immunological cross-reaction suggests that ovine and bovine leukemia viruses are genetically highly related.

Cross-neutralization of ovine and bovine C-type leukemia virus-induced syncytia formation.

Ovine leukemia virus (OLV) could not be distinguished from bovine leukemia virus (BLV) morphologically. Both C-type RNA tumor virus-producing cells induced syncytia when cocultivated with several indicator cells including XC and KC cells. Syncytia formation could be blocked by antibodies against OLV and BLV, indicating that fusion was virus mediated. Furthermore, antibodies against OLV and BLV exhibited reciprocal syncytial blocking properties, suggesting that OLV and BLV were closely related viruses.
