Piroplasmosis – Insights on how to prevent and prevail against the protozoal disease

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.

Anaplasmosis – Small bacterium that causes big issues

Anaplasmosis is a disease transmitted by ticks. The causative agent is a bacterium, Anaplasma marginale that lives in an animal's red blood cells. It's crucial producers and practitioners be aware of anaplasmosis as clinical signs can mimic other diseases. In this episode, Dr. Brandon Dominguez and Dr. Alexis Thompson discuss the disease, clinical signs, and testing considerations with Dr. Suzanna Storms, TVMDL's new serology section head.

Next-Generation Sequencing – Analyzing the entire library instead of just a book

Those in veterinary medicine have probably heard of next-generation sequencing (NGS), but what exactly is involved in this methodology? In this episode, Dr. Brandon Dominguez and Carlos Rodriguez discuss NGS, it's value, and how it's applied at TVMDL with Assistant Section Head for Research and Development Dr. Ellen-Ruth Alexander-Morris. Using NGS technology, TVMDL has the ability to analyzes hundreds of data points at one time which lends toward a quicker, more accurate diagnosis for clients. This is an exciting episode that shines a light into the future of veterinary diagnostics.

Orf – Assessing the rapid risk to ruminants

Orf is a highly contagious virus. Sheep and goats are the species primarily affected, with young lambs and kids being more susceptible due to their underdeveloped immune systems. It's critical that if you suspect Orf in your flock or herd that critical steps are implemented to mitigate the spread. In this episode Dr. Brandon Dominguez discusses biosafety practices, testing options, and other essential factors with Dr. Michael Piccione and TVMDL's new serology section head, Dr. Suzanna Storms.

PCR Testing – The whats, whens, and hows

PCR testing is impressive. It's considered the go-to method for several cases when sensitive, timely results are needed. However, it's important samples are submitted appropriately and in the right circumstances in order to the get most out of results. In this episode, Dr. Brandon Dominguez and Dr. Semira Mancill discuss the science behind PCR testing and how to ensure results answer critical questions with Dr. Megan Schroeder, molecular diagnostics assistant section head.
