Effects of Naturally Occurring Mutations in Bovine Leukemia Virus 5′-LTR and Tax Gene on Viral Transcriptional Activity

Pathogens, 2020
Bovine leukemia virus (BLV) is a deltaretrovirus infecting bovine B cells and causing enzootic bovine leucosis (EBL). The long terminal repeat (LTR) plays an indispensable role in viral gene expression. The BLV Tax protein acts as the main transactivator

Detection and Molecular Characterization of Bovine Leukemia Virus in Egyptian Dairy Cattle

Frontiers in Veterinary Science, 2020
Bovine leukemia virus (BLV) causes enzootic bovine leukosis (EBL), the most common neoplastic disease in cattle worldwide. The first EBL outbreak in Egypt was reported in 1997. To date, there are few studies regarding BLV diagnosis using only serological

Seroprevalence and haemato-biochemical effects of bovine leucosis in buffalo, Punjab, Pakistan

Veterinární Medicína, 2023
Enzootic bovine leucosis is caused by bovine leukaemia virus (BLV), a Deltaretrovirus belonging to the family Retroviridae. BLV causes huge economic losses to the dairy industry in the form of decreased milk production, premature culling, and poor ...

Molecular Epidemiological and Serological Studies of Bovine Leukemia Virus in Taiwan Dairy Cattle

Frontiers in Veterinary Science, 2019
Bovine leukemia virus (BLV) infection results in a decrease in milk yield and quality, a compromise in immunity, and shortening in the longevity of cows. The current status of BLV infection of dairy cattle in Taiwan remains unclear.

Exploratory study of volatile fatty acids and the rumen-and-gut microbiota of dairy cows in a single farm, with respect to subclinical infection with bovine leukemia virus

Annals of Microbiology, 2023
Background Subclinical infection with bovine leukemia virus (BLV) in cows can cause economic losses in milk and meat production in many countries, as BLV-related negative effects.

BLV-CoCoMo-qPCR-3: Improved BLV-CoCoMo-qPCR for Bovine Leukemia Virus Detection by Mixing Probes Targeting all BLV Variants [PDF]

, 2020
Abstract Background: The bovine leukemia virus (BLV) is the causative agent of enzootic bovine leukosis, the most common neoplastic disease in cattle. The proviral load (PVL) is an important index for estimating disease progression. Previously, we developed a quantitative real-time PCR (qPCR) assay to measure the PVL of BLV using coordination ...

BLV-CoCoMo-qPCR: a useful tool for evaluating bovine leukemia virus infection status

BMC Veterinary Research, 2012
Background Bovine leukemia virus (BLV) is associated with enzootic bovine leukosis, which is the most common neoplastic disease of cattle. BLV infects cattle worldwide, imposing a severe economic impact on the dairy cattle industry.

Correlation between the Biodistribution of Bovine Leukemia Virus in the Organs and the Proviral Load in the Peripheral Blood during Early Stages of Experimentally Infected Cattle

Pathogens, 2023
Bovine leukemia virus (BLV) is the etiological agent of enzootic bovine leukosis. However, the propagation and distribution of BLV after primary infection still need to be fully elucidated.
