Abstract :
The relative virus load of bovine leukemia virus (BLV) infected cattle was measured by an immunoperoxidase infectivity assay (IPIA), and by immunoperoxidase staining of cultured leukocytes using a monoclonal antibody to the capsid protein (p24) of BLV. The results of paired sample data taken at different time points spanning 2–3 years show that BLV-infected cattle are stable regarding the amount of BLV produced by their peripheral blood mononuclear cells (PBMCs). Spearmanʹs Rank Correlation demonstrated significant relationships between data from individual cattle taken at four different time points. In addition, this study documents the large range of variation in the virus load of individual cattle.
