A survey for maternal antibodies to bovine leukemia virus (BLV) in calves born to cows infected with BLV.

The Japanese Journal of Veterinary Science, 1984
Seventy calves born to the cows infected with bovine leukemia virus (BLV) were examined periodically for the maternal antibodies to BLV. Antibodies to BLV were negative in all of 22 except one calves examined at precolostrum stage, but they converted into positive 24hrs postcolostrum. Most of the 70 calves being positive in the antibodies to BLV at the

A rapid and simple clonality assay for bovine leukemia virus-infected cells by amplified fragment length polymorphism (AFLP) analysis

Microbiology Spectrum
Enzootic bovine leukosis (EBL), although eradicated in some European countries, is still the most common neoplastic disease of cattle, caused by the bovine leukemia virus (BLV).

Bovine Leukemia Virus DNA in Human Breast Tissue

Emerging Infectious Diseases, 2014
Bovine leukemia virus (BLV), a deltaretrovirus, causes B-cell leukemia/lymphoma in cattle and is prevalent in herds globally. A previous finding of antibodies against BLV in humans led us to examine the possibility of human infection with BLV. We focused

Bovine Leukaemia Virus Tax Antigen Identification in Human Lymphoma Tissue: Possibility of onco-protein Gene Ttransmission

Research in Molecular Medicine, 2019
Background: Bovine leukaemia virus (BLV) is the cause of enzootic bovine leukaemia which belongs to retroviruses including Human T-cell leukaemia virus and simian T-lymphotropic virus. Due to this familiarity, the possibility of virus (BLV) transfer from

Activation of BLV Transcription by NF-κB and Tax

Virology, 1998
Bovine leukemia virus (BLV) is the causative agent of bovine leukosis, a naturally occurring fatal disease in cattle. BLV transcription is regulated by cellular transcription factors and the virally encoded oncoprotein Tax. In this report, we investigated the functional role of the putative NF-kappa B binding site recently identified in the BLV ...

Investigating BoLA Class II DRB3*009:02 carrying cattle in Japan

Veterinary and Animal Science
Enzootic bovine leukosis (EBL) is a malignant lymphoma of cattle that is mainly caused by bovine leukemia virus (BLV) infection. In this study, PCR-RFLP was used to investigate the frequency of the DRB3*009:02 allele in several farms with different herd ...

Dairy Cows Naturally Infected with Bovine Leukemia Virus Exhibit Abnormal B- and T-Cell Phenotypes after Primary and Secondary Exposures to Keyhole Limpet Hemocyanin

Frontiers in Veterinary Science, 2017
Bovine leukemia virus (BLV) is a retrovirus that is highly prevalent in US dairy herds: over 83% are BLV infected and the within-herd infection rate can be almost 50% on average.

Impact of high proviral load on milk production, reproduction and subclinical diseases in dairy cows infected with bovine leukemia virus

Frontiers in Veterinary Science
IntroductionBovine Leukemia Virus (BLV) prevalence remains high in dairy cattle in North America. Quantifying the proviral load (PVL) in BLV-positive cows can be used to control this disease in herds where BLV is prevalent by focusing culling of high PVL

Polymorphism and expression of the tumour necrosis factor-alpha (TNF-alpha) gene in non-infected cows and in cows naturally infected with the bovine leukaemia virus (BLV)

Veterinární Medicína, 2016
The objective of this study was to determine the influence of TNF-alpha gene polymorphism at position -824 A > G on TNF-alpha gene expression in BLV-positive animals with aleukaemic (AL) and persistent lymphocytosis (PL) forms of enzootic bovine ...
