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.

Humoral and cellular responses in calves experimentally infected with Bovine Leukemia Virus (BLV)
Veterinary Immunology and Immunopathology, 1985In order to elucidate whether infection by Bovine Leukemia Virus (BLV) might induce an immunodeficient state, we inoculated sixteen calves with BLV. The calves were followed up for two years and were tested for humoral and cellular responses using various parameters, namely the appearance of antibodies to the BLV antigens, the changes in the numbers of

Glycoprotein and protein composition of bovine leukemia virus (BLV).
Neoplasma, 1981Highly purified preparation of bovine leukemia virus (BLV) was obtained by the method described in this communication. BLV was isolated from cell-free culture medium, harvested from BLV-producing cell-line FLK. Polyacrylamide gel electrophoresis of BLV proteins and glycoproteins, in comparison with avian myeloblastosis virus (AMV), confirmed high ...

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.

Abstract In this report data presented show that the bovine leukemia virus (BLV) is infectious for cells of various species including humans. Bat monolayer cell cultures were the most permissive for replication of BLV and provided an abundant source of virus for characterization studies.

Levels and role of cytokines in bovine leukemia virus (BLV) infection.
Leukemia, 1997Bovine leukemia virus belongs to a small subfamily of exogenous retroviruses that includes the human retroviruses HTLV-1, HTLV-II and the simian virus, STLV-1. Like other retroviruses, infection with BLV results in deregulation of the host immune system at both humoral and cellular levels.

Blood dendritic cells in cattle infected with bovine leukemia virus (BLV): isolation and phenotyping
Polish Journal of Veterinary Sciences, 2012AbstractDendritic cells (DCs) are most potent antigen presenting cells (APCs) with unique ability to prime effective immune responses. They express higher levels of MHC class II and accesory molecules on their surface, than other professional APCs. The investigations were performed on DCs generated from blood with the use of microbeads magnetically ...

An experimental model of chronic infection with bovine leukemia virus (BLV) was established in young calves within a relatively short time. In the sera of all infected calves, precipitating antibodies were detected within 5 weeks after infection but upon disease progression pattern of cellular profiles varied.

The improvement of monitoring methods of cattle infection with bovine leukemia virus (BLV).
Polish journal of veterinary sciences, 2003This study demonstrates the usefulness of PLA and nested-PCR methods for the detection of cattle infection with enzootic bovine leukemia virus. Serological control with PLA was by 1.7% more sensitive than reference ELISA examination. Both the DNA of env-BLV gene in NCR, V-NCR, FLK and in recombinated AG clone cells, as well as in the whole blood and in
