Evaluation of bovine leukaemia virus infection control measures in Japanese Black beef cattle breeding farms: A 7-year longitudinal study based on proviral load. [PDF]

Vet Rec Open
Abstract Background Bovine leukaemia virus (BLV) infection remains a major problem for Japanese Black (Wagyu) cattle, and effective and sustainable control measures are essential to prevent its spread in breeding herds. This study aimed to monitor the BLV infection status of all cattle at a Japanese Black breeding farm in Kagoshima Prefecture, Japan ...

Application of the Luminescence Syncytium Induction Assay to Identify Chemical Compounds That Inhibit Bovine Leukemia Virus Replication

Viruses, 2022
Bovine leukemia virus (BLV) infection causes endemic bovine leukemia and lymphoma, resulting in lower carcass weight and reduced milk production by the infected cattle, leading to economic losses.

Diagnosis and Early Prediction of Lymphoma Using High-Throughput Clonality Analysis of Bovine Leukemia Virus-Infected Cells

Microbiology Spectrum, 2022
Bovine leukemia virus (BLV), a retrovirus, infects B cells of ruminants and is integrated into the host genome as a provirus for lifelong infection. After a long latent period, 1% to 5% of BLV-infected cattle develop aggressive lymphoma, enzootic bovine ...

First Evidence of Bovine Leukemia Virus in Culicoides Biting Midges and the Stable Fly Stomoxys calcitrans Collected on Cattle Farms in Poland. [PDF]

Transbound Emerg Dis
Bovine leukemia virus (BLV) is a cell‐associated retrovirus of cattle transmitted mainly through the transfer of infected lymphocytes, but the possible role of hematophagous insects in its epidemiology remains incompletely understood. This study investigated BLV DNA in field‐collected Culicoides biting midges and Stomoxys calcitrans from cattle farms ...

Molecular Characterization of Bovine Leukemia Virus with the Evidence of a New Genotype Circulating in Cattle from Kazakhstan

Pathogens, 2022
Bovine leukemia virus (BLV) is a retrovirus that causes enzootic bovine leukosis (EBL) and has worldwide distribution. Infections with BLV have been reported in cattle from Kazakhstan but the virus has not yet been thoroughly characterized. In this study,

Impact of BoLA-DRB3 Polymorphisms on Clonality of Bovine Leukaemia Virus-Infected Cells of Cattle With Lymphoma. [PDF]

HLA
ABSTRACT Bovine leukaemia virus (BLV) infects cattle, integrates into the host genome as a provirus, and induces a persistent infection that remains asymptomatic but can cause leukaemia/lymphoma. Most BLV‐infected cell clones are created by massive depletion, and a few of these infected cell clones expand through the mitotic cycle, leading to the onset

Bovine leukemia virus: current perspectives [PDF]

, 2017
Enzootic bovine leukosis, caused by bovine leukemia virus (BLV), is the most common neoplasm of dairy cattle. Although beef and dairy cattle are susceptible to BLV infection and BLV-associated lymphosarcoma, the disease is more commonly detected in dairy

Purification of a Glycoprotein from Bovine Leukemia Virus (BLV)

Zeitschrift für Naturforschung C, 1977
Abstract A precipitating antigen of bovine leukemia virus was isolated by isoelectric focusing and Sephadex gel filtration. In SDS-polyacrylamide gel electrophoresis it was found to be a homogeneous protein with a relative molecular weight of 69 000 daltons.

MicroRNAs Encoded by Bovine Leukemia Virus (BLV) Are Associated with Reduced Expression of B Cell Transcriptional Regulators in Dairy Cattle Naturally Infected with BLV. [PDF]

Front Vet Sci, 2017
Bovine leukemia virus (BLV) is estimated to infect over 83% of dairy herds and over 40% of all dairy cows in the United States. While, BLV only causes leukemia in a small proportion of animals, research indicates that BLV+ cattle exhibit reduced milk ...
