In late March, the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) diagnosed senna toxicosis in two separate goat herds, from west and central Texas. In the first case, a 2-month-old goat kid was found suddenly dead along with one other goat kid. A third surviving kid was reported to be clinically ill. Histologically, the heart…
Nitrate toxicity occurs when animals consume food or water that contains high levels of nitrates. In the rumen, nitrates are converted into a smaller compound called nitrites, which are then absorbed into the bloodstream. Ruminants are particularly susceptible because of their consistent grazing habits. Alexis Thompson, DVM, Ph.D., DACVPM, is the resident director at the…
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…
John Reagor, PhD, Veterinary Toxicologist Emeritus, passed away on April 20. Reagor fervently served the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) as the agency’s toxicologist for 50 years. During his time at TVMDL he garnered a national reputation for his expertise of various toxins. He led TVMDL’s toxicology section to become one of the…
The Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) offers digital toxicology to account-holding clients. Digital toxicology provides evaluation of photos taken with smart phones, or other digital cameras, and an official report identifying items photographed (where possible) including an attachment with labeled photos for later reference – an advantage over shipping items to the laboratory…
In reflecting upon yet another major livestock show season in Texas, it is important to keep in mind the possibility of copper toxicity, particularly in sheep and goats. Sheep are particularly sensitive to excess copper in their diets. Although goats are not as sensitive as sheep, they can still become intoxicated with too much copper. It…
Beetles found in a new batch of alfalfa hay were submitted to the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) for identification. TVMDL’s toxicology section can identify toxic and non-toxic beetles using microscopic examination. The beetles submitted were identified as Tiger beetles (Cicindelidae sp.) (Figure 1). Tiger beetles are characterized by having large, carnivorous mouth parts…
The Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) was contacted by a client who was concerned a group of horses had potentially consumed gopher bait containing an anticoagulant (diphacinone) as the toxic agent. Providing treatment for large animals with the antidote for anticoagulant intoxication can be challenging, therefore the suggestion was made to submit samples…
This assay utilizes rtPCR technology on E. coli isolates recovered from ruminant samples. Samples are recovered by the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) bacteriology section to further characterize the potential of the isolate to be participating in the current patient clinical syndrome. The significance of the detected genes should be interpreted with the…
