Bovine leukemia virus (BLV) is a retrovirus which causes enzootic bovine leukosis in cattle.It is closely related to the human T‑lymphotropic virus type 1 ().BLV may integrate into the genomic DNA of B‑lymphocytes as a DNA intermediate (the provirus), or exist as unintegrated circular or linear forms.

Outside the United States, blood tests made up of the majority of the same biochemical tests are called urea and electrolytes (U&E or "U and Es"), or urea, electrolytes, creatinine (UEC or EUC or CUE), and are often referred to as 'kidney function tests' as they also include a calculated estimated glomerular filtration rate. The BMP provides ...
A typical (uninfected) monocyte on blood smear. Anaplasma bovis is a gram negative obligate intracellular bacteria. [8] The bacteria lives within the mononuclear cells of cattle, specifically monocytes. When the bacteria is suspected you can take a blood smear and observe the cells for presence of A. bovis within.
A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing.
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick.

Eye Ring. Bovine malignant catarrhal fever (BMCF) is a fatal lymphoproliferative disease [1] caused by a group of ruminant gamma herpes viruses including Alcelaphine gammaherpesvirus 1 (AlHV-1) [2] and Ovine gammaherpesvirus 2 (OvHV-2) [1] [3] These viruses cause unapparent infection in their reservoir hosts (sheep with OvHV-2 and wildebeest with AlHV-1), but are usually fatal in cattle and ...
An interesting feature is the remarkable tolerance to nagana pathology shown by some breeds of cattle, notably the N'Dama – a West African Bos taurus breed. This contrasts with the susceptibility shown by East African B. indicus cattle such as the zebu .
