Diseases & Diagnoses

Bovine Theileria refers to a group of protozoal parasites that infect cattle. Among them, Theileria orientalis is particularly important, as it’s been associated with outbreaks causing anemia, decreased productivity, and even death in severe cases. In this episode, Dr. Brandon Dominguez and Dr. Alexis Thomspon discuss TVMDL's new PCR assay with Molecular Diagnostics Assistant Section Head Dr. Megan Schroeder.

Multiplex assays are a really useful diagnostic tool for testing/targeting multiple pathogens at one time.  Clients obtain results for multiple targets at a reduced cost than if they were testing for each target individually. In this episode, Dr. Brandon Dominguez and Dr. Michael Piccione discuss the value of multiplex assays with Dr. Megan Schroeder, assistant section head for molecular diagnostics.

Biosecurity is an essential part of any animal operation. TVMDL offers a panel aimed at screening for several significant diseases in sheep and goats. In this episode, Dr. Brandon Dominguez, Dr. Michael Piccione, and Serology Section Head Dr. Suzanna Storms discuss the tests included in the panel and how producers can leverage that information into making herd health decisions.

Although mycoplasma and ureaplasma are closely related, the latter pathogen holds some key differences that could be pinpointed through diagnostic testing. In this episode, Dr. Brandon Dominguez and Dr. Alexis Thompson chat with Dr. Tegner Jacobson, microbiology section head in Canyon, to discuss the two pathogens, how they're different, and how diagnostic testing can assist practitioners in determining a specific diagnosis.

For many, anthrax isn't outside the realm of normal. Those living within the geographic triangle connecting Uvalde, Ozona, and Eagle Pass or otherwise known as the "Anthrax Zone" are familiar with this disease as it's been endemic to the area for several years. On average, TVMDL detects one to two cases from this area each year. Though anthrax is serious zoonotic disease, producers and practitioners should not be weary if armed with the correct knowledge and precautions. In this episode, Assistant Agency Director for Diagnostic Services Dr. Terry Hensley discusses an overview of anthrax, it's historical prevalence, and how you can submit samples for anthrax testing while keeping your staff and our staff safe.

Cache Valley virus (CVV) is a mosquito-borne virus that has as significant impact on sheep and wildlife. Despite it's impact, CVV does not garner the same attention as similar mosquito-borne viruses like Bluetongue and West Nile. In this episode, Dr. Brandon Dominguez and Dr. Alexis Thompson discuss CVV, common clinical signs, and testing considerations with Assistant Agency Director for Microbiology Dr. Erika Schwarz.

Sample pooling can be a cost effective way to screen a large group of animals for a disease. However, it's important pooling is only used in certain circumstances to ensure results are reliable. In this episode, Dr. Brandon Dominguez and Dr. Alexis Thompson chat with Assistant Agency Director for Microbiology Dr. Erika Schwarz to cover the pooling method and the instances where pooling is most effective.

Urine protein creatinine ratio (UPC) can be incredibly insightful. With a single urine sample, TVMDL can help clients determine if a pet is losing too much protein in their urine. This information can lead treatment decisions and get ahead of kidney disease. In this episode Dr. Brandon Dominguez and Dr. Cathy Campbell discuss UPC testing and its value with Kellye Stillwell, technician in the College Station lab's clinical pathology section.

In addition to encompassing two poultry specific labs, TVMDL supports the poultry industries by managing two state programs focused on flock health. In this episode, Dr. Brandon Dominguez chats with Poultry Programs Administrator Sydney Rosario about the National Poultry Improvement Plan (NPIP) and the Texas Pullorum-Typhoid (PT) Program. They're joined by DeEtte Mills and Holly Hull of TVMDL's Gonzales lab to discuss the tests and services their lab provides commercial and backyard producers.

Most equine owners are aware of the dangers associated with piroplasmosis. Although it's mostly associated with transmission through ticks, most cases in the United States are caused by human-meditated spread. Practices such as reusing needles, syringes, IV sets, and other blood-contaminated instruments are the primary methods of transmission. In this episode, Dr. Brandon Dominguez, Dr. Semira Mancill, and Dr. Terry Hensley discuss clinical signs, or the lack thereof in some cases, testing options, and effective treatments.
