Identification of Bovine Leukemia Virus (BLV) in Milk: Scoping review
FOOD METAENGINEERING, 2023Introduction: Since 2019, there has been a growing interest in assessing the potential risks of animal viral infections mutating into a form dangerous for humans. Research in the field of livestock product safety is being conducted in several directions, including the analysis and assessment of the impact of the most common cattle diseases on the ...

Circulating immune complexes in bovine leukemia virus (BLV)-infected cattle
Veterinary Immunology and Immunopathology, 1992Circulating immune complexes (ICs) were detected in the sera of bovine leukemia virus (BLV)-seropositive cattle. Immune complexes were precipitated in 2.5% polyethylene glycol (PEG) and further dissociated. Bovine leukemia virus antigens, IgG and IgM molecules were detected after solubilization in the presence of sodium dodecyl sulphate, and ...

A blocking enzyme-linked immunosorbent assay (ELISA) for the detection of antibodies against bovine leukemia virus (BLV) is described. The test is based on the biotin-streptavidin system using unlabelled polyclonal bovine IgG against BLV as catching antibody and biotinylated bovine anti-BLV IgG as detecting antibody.

Bovine leukemia virus (BLV)—A structural model based on chemical crosslinking studies
Virology, 1984Nearest neighbor relationships between lipid and protein as well as between high-molecular-weight viral RNA and protein were investigated in bovine leukemia virus (BLV) particles using chemical crosslinking reagents. Separation of dimethyl suberimidate (DMS) induced lipid-protein complexes by sodium dodecyl sulfate-polyacrylamide gel electrophoresis ...

Journal of Virological Methods, 2023
Bovine leukemia virus (BLV) is an enveloped virus, found worldwide that can infect cattle and induce many subclinical symptoms and malignant tumors. BLV infection causes severe economic losses in the cattle industry. The identification of BLV-infected cattle for segregation or elimination would be the most effective way to halt the spread of BLV ...

Synthesis of functional bovine leukemia virus (BLV) p34 protein by recombinant baculoviruses
Virology, 1989The bovine leukemia virus (BLV) p34tax (also called tat, p34, XLOR gene product) is a 34-kDa polypeptide encoded in the 3'-terminal region of the virus. This protein is responsible for positive transcriptional trans-activation of promoter elements located within the BLV long-terminal repeat.

A Comparative Study of Bovine Leukemia Virus (BLV) Detection Methods
1985Electron Microscopy (EM), Reverse Transcriptase test (RT), Concurrent Radioimmunoassay (cRIA) for major core protein p-24, and RNA dot-blot hybridization were used for quantitative BLV detection in culture fluids of BLV producing Foetal Lamb Kidney (FLK) cell lines and short term lymphocyte cultures.

Molecular Characterization of a Variant of Proviral Bovine Leukaemia Virus (BLV)
Journal of Veterinary Medicine, Series B, 1996Southern-blot hybridization and partial sequencing of the pol and env genes were used to characterize BLV-integrated provirus of seropositive cattle from two dairy herds in northern Italy. Comparison of the data obtained with those of previously characterized BLV strains from other geographic areas (Australia, Belgium, Japan and USA) revealed the ...

Experimental infection of sheep with bovine leukemia virus (BLV).
Polskie archiwum weterynaryjne, 1992Nine groups of sheep have been experimentally infected with different doses of BLV and by various routes. An immunological response of animals, as well as clinical symptoms of leukosis in the experimental sheep were investigated within several years or months.
