[Role of the expression of the bovine leukemia virus in the pathogenesis of hemoblastoses].
The role of bovine leukemia virus (BLV) expression was demonstrated in normal, BLV-infected and leukemic cattle. The studies established the changeable character of viremia on the basis of BLV p24 expression in blood plasma and native leukocyte lysates. The experiment revealed a marked regularity: a decrease of antibody titer in blood serum--the appearance of the virus in the body--lymphocytosis. The development of lympholeukemia shortly after experimental infection was detected in animals with an antigen regularly detectable in the plasma.
