Detection of Borrelia species, including B. burgdorferi, B. hermsii, B. parkeri, and B. turicatae by real time PCR. Lyme Borreliosis (Borrelia burgdorferi) DNA is not typically detected in peripheral blood, even when Lyme disease is the cause of clinical signs. This PCR for Borrelia species is offered for the detection of Tick-Borne Relapsing Fever Borrelia…

With today’s high cattle values and the increasing cost of replacement heifers, these losses can quickly become financially devastating. Pregnancy loss may also indicate underlying infectious disease, which can affect the entire health of a herd. For these reasons, prompt investigation…

Detection of Brucella spp. by culture.
Fifteen crossbred calves were placed in a pasture with a burn-pile. The day after they were provided with Johnson grass hay, one calf was found dead. Two days later, three calves were walking abnormally and had diarrhea. Feces from those calves was submitted to the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) for testing. Fecal…
Detection of Campylobacter spp. by culture.
An 11-year-old Corgi mix was presented to the veterinarian with intermittent diarrhea and inappetence. History noted the dog had clinical signs of gastrointestinal (GI) disease for the past few months, was current on vaccinations and was fed a raw food diet.

Canine hepatozoonosis is a debilitating, tick-borne disease caused by Hepatozoon americanum, a protozoal parasite transmitted by the Gulf coast tick (Amblyomma maculatum). Affected dogs may have waxing and waning clinical signs and typically present with a fever, weakness, and reluctance to move. Other clinical signs can include muscle atrophy, weight loss, and mucopurulent ocular discharge. Late…
When horses ingest the cantharidin toxin through hay or alfalfa contaminated with “blister” beetles, the outcome is often fatal. Toxicosis occurs rapidly; as little as four grams of dried beetles may contain fatal levels of cantharidin. Cantharidin is extremely toxic and fast-acting, quickly affecting a horse’s ability to function. All blister beetles carry cantharidin and…
