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

Effect of BLV Infection on the Immune Function of Polymorphonuclear Neutrophil in Dairy Cows

Frontiers in Veterinary Science, 2021
Enzootic bovine leukemia is a late-onset, neoplastic infection caused by the bovine leukemia virus (BLV). BLV infection hinders the function of the immune system and induces other diseases, which negatively affects the performance and health of the ...

Immuno‐Informatics Design of Multi‐Epitope Vaccine Candidate Against Anaplasma phagocytophilum Using Major Surface Protein 4 (MSP‐4) Antigen

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims Bovine anaplasmosis is an intracellular tick‐borne, non‐contagious disease caused by gram‐negative bacteria of the family Anaplasmataceae and order Rickettsia. Anaplasma phagocytophilum is the etiological agent for human granulocytic anaplasmosis associated with severe health implications in parts of Europe and the USA and ...

Computational and Experimental Development of a Novel Multi‐Epitope Vaccine Candidate Against Bovine Leukaemia Virus

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study designs a novel multi‐epitope vaccine against bovine leukaemia virus using immunoinformatics. The construct demonstrates high antigenicity, stability, and strong receptor binding, indicating its potential as an effective recombinant vaccine candidate for further experimental validation .

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Stage‐Dependent Transcriptional Reprogramming of B‐Cell Receptor Signaling and Antigen Presentation During Bovine Leukemia Virus–Driven Lymphomagenesis

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Bovine leukemia virus (BLV), an oncogenic deltaretrovirus, establishes lifelong infection in cattle and induces enzootic bovine leukosis in a subset of animals following prolonged latency. Despite extensive evidence of immune dysregulation, stage‐specific transcriptional reprogramming of B cells, the primary viral reservoir remains ...

Co-expression of bovine leukemia virus and bovine foamy virus-derived miRNAs in naturally infected cattle

Microbiology Spectrum
Among the viruses that encode microRNAs (miRNAs) and infect cattle, such as bovine leukemia virus (BLV), bovine foamy virus (BFV), and Bovine herpesviruses, BLV has gained attention due to the critical role that BLV-miRNAs play in inducing lymphosarcoma ...
