Serological investigations on bovine leukemia virus

Veterinary Microbiology, 1976
Abstract A complement fixation test was developed to investigate the presence of antibodies to the bovine leukemia virus. For 226 animals from 13 different herds it was possible to correlate the results of the serological test and the white blood picture, where the criteria established by the commission of the European communities were used.

Immunological implications of bovine leukemia virus infection

Research in Veterinary Science, 2017
This study examined neutrophil and monocyte functions and the blood lymphocyte profile of naturally BLV-infected cows with or without persistent lymphocytosis (PL). The percentage of neutrophils and monocytes that phagocytosed Staphylococcus aureus was lower in BLV-infected dairy cows, particularly those with PL.

Structure of a Defective Provirus of Bovine Leukemia Virus

Microbiology and Immunology, 1987
AbstractDefective proviruses of bovine leukemia virus (BLV) in the genomes of infected cells were investigated by using Southern blotting hybridization analysis with various portions of a cloned BLV DNA as probes. When nine independent tumors of enzootic bovine leukosis with a single proviral copy per cell were examined, a single defective provirus of ...

Evidence in support of a virus etiology for bovine leukemia

Cancer, 1967
Virus-like particles resembling the C-type particles of murine leukemia were detected in tissue biopsies and more frequently in thin sections of pellets following density gradient centrifugation of milk from leukemic cows and cows in a high incidence leukemic herd. These particles had a buoyant density in potassium citrate and sucrose gradients of 1.15
