Photosensitization is a serious skin condition in horses and cattle caused by a hazardous combination of certain plants and ultraviolet (UV) light. Certain plants contain photodynamic agents, which then cause a reaction in the animal’s body that leads to ultra-sensitive skin. This condition is specific to lightly or non-pigmented animals or areas of an animal…
Identification of both toxic and non-toxic plants.
The non-stick coating polytetrafluoroethylene (TeflonTM) on cookware, light bulbs, and ovens releases fluorinated gases upon overheating. This is particularly important with pet birds, but can be observed in poultry with polytetrafluoroethylene-coated heat lamp bulbs. These gases are highly toxic to the epithelium of the deep airways and endothelium of the blood capillaries. Birds exposed to…
TVMDL received a full set of fresh and fixed tissue samples and stomach content from a four-year-old Belgian Tervuren for testing.

A two-month-old, 150-pound, Brahman-cross heifer calf was observed with neurologic signs following application of what was believed to be a permethrin-based insecticide. The calf died following symptomatic treatment. Fresh and fixed tissue samples were submitted to the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) for testing. A portion of fresh brain was extracted and analyzed…
A six-month-old, intact male, Doberman Pinscher was observed chewing on a small zip-lock bag and then spit it out. The dog became hyperactive and difficult to control. The dog also developed a bloody, mucoid stool. No vomiting was noted. The small zip-lock bag was submitted to the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) for…
A 7-year-old pastured mare suffered an acute onset of hemolytic anemia and hematuria. The blood drawn for analysis was hemolyzed and dark. The mare died about three hours after intravenous fluid therapy was begun. Whole blood, serum and a blood smear were submitted to the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) for evaluation. Clinical…
