Hot topic: Bovine leukemia virus (BLV)-infected cows with low proviral load are not a source of infection for BLV-free cattle [PDF]

, 2016
The bovine leukemia virus (BLV) causes leukemia or lymphoma in cattle. Although most BLV-infected animals do not develop the disease, they maintain the transmission chain of BLV at the herd level. As a feasible approach to control the virus, selection of

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

HBP1 mRNA expression levels in B cells derived from BLV negative and BLV-infected cattle, and an EBL derived tumor cell line, KU-17.

, 2021
HBP1 mRNA copy number was normalized to ACTB mRNA copy number. The expression levels of HBP1 mRNA in B cells derived from BLV-infected cattle did not differ from those of BLV-uninfected cattle (p = 0.3217). HBP1 mRNA expression in the bovine B cell tumor

Detection of Bovine Leukemia Viruses(BLV) in Mammary Tissues of BLV Antibody-Positive Cows Affected by Subclinical Mastitis.

Journal of Veterinary Medical Science, 1997
The mammary tissues of 6 cows with bovine leukemia virus (BLV) antibody and subclinical mastitis were investigated histopathologically, and their organ cultures were ultrastructurally observed. Numerous BLV particles, 110 to 120 nm in diameter, were seen around lymphocytes, which had infiltrated into mammary alveoli and showed blastogenesis under ...

An 8-year longitudinal sero-epidemiological study of bovine leukaemia virus (BLV) infection in dairy cattle in Turkey and analysis of risk factors associated with BLV seropositivity

, 2015
Enzootic bovine leukosis (EBL) which is caused by bovine leukaemia virus (BLV) has an important economic impact on dairy herds due to reduced milk production and restrictions on livestock exports.

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

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.

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).
