Veterinary pathologists are veterinarians who specialize in the diagnosis of diseases through the examination of animal tissue and body fluids. [1] Like medical pathology, veterinary pathology is divided into two branches, anatomical pathology and clinical pathology. Other than the diagnosis of disease in food-producing animals, companion ...
Tongue lesions on confirmed BVD/MD case (mucosal disease form) Bovine viral diarrhea (BVD), bovine viral diarrhoea (UK English) or mucosal disease, previously referred to as bovine virus diarrhea (BVD), is an economically significant disease of cattle that is found in the majority of countries throughout the world.

Hepatotoxicity may manifest as triglyceride accumulation, which leads to either small-droplet (microvesicular) or large-droplet (macrovesicular) fatty liver. There is a separate type of steatosis by which phospholipid accumulation leads to a pattern similar to the diseases with inherited phospholipid metabolism defects (e.g., Tay–Sachs disease )
A cannula in a cow's side. A cannulated cow or fistulated cow refers to a cow that has been surgically fitted with a cannula. [1] A cannula acts as a porthole-like device that allows access to the rumen of a cow, to perform research and analysis of the digestive system and to allow veterinarians to transplant rumen contents from one cow to another.
A wide variety of clinical signs have been described for HS in cattle and buffaloes. [2] The incubation periods for buffalo calves 4–10 months of age varies according to the route of infection. [20] The incubation period is 12–14 hours for subcutaneous infection, approximately 30 hours for oral infection, and 46–80 hours for natural exposure.
General systemic signs include diarrhea, anorexia, and weight loss. Infected animals may develop a jaundiced look which then turns into paleness around the eyes, muzzle, lips, and teats of the cattle. [2] All cattle are susceptible to infection by Anaplasma marginale, but the severity worsens with age increase. Older cattle tend to exhibit the ...
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. [2]
Therefore, manual diagnosis is done at many levels. Diagnosis basically relies on a combination of postmortem analyses, clinical signs displayed by the animals, and response to drenching. In heavy infection, symptoms are easily observed in sheep and cattle as they become severely anorexic or inefficiently digest food, and become unthrifty ...
