Exploration of microRNA Biomarkers in Blood Small Extracellular Vesicles for Enzootic Bovine Leukosis. [PDF]

Microorganisms, 2023
Enzootic bovine leukosis (EBL) is a B-cell lymphosarcoma caused by the bovine leukemia virus (BLV). While most infected cattle show no clinical signs, approximately 30% of infected cattle develop persistent lymphocytosis (PL), and a small percentage may ...

Circulating Cell-Free DNA of Bovine Leukemia Virus: A Promising Biomarker for Enzootic Bovine Leukosis. [PDF]

Microbiol Immunol
Bovine leukemia virus (BLV) causes Enzootic bovine leukosis (EBL) in approximately 1%–5% of infected cattle after a long latent period. Few biomarkers effectively distinguish non‐EBL from EBL cattle.

Enzootic bovine leukosis in a cow

Brazilian Journal of Veterinary Pathology, 2023
A 5-year-old, Holstein-Friesian dairy cow was evaluated by a veterinary practitioner for a 30-day history of unilateralexophthalmos (Fig. 1). After 15 days, the cow presented lameness followed by progressive weight loss and pelvic limbs paresis,culminating in persistent sternal recumbency (Fig. 2).
