π΄ New research from our team is helping horses survive one of the most feared diseases in the industry.
A new study led by Drs. Megan Marchitello, Krista Estell, Elsa Ludwig, and Professor Emeritus Nathaniel White of Virginia Tech's Marion duPont Scott Equine Medical Center and former Virginia State Veterinarian Abby M. Sage found that combining valacyclovir (an antiviral) with heparin (an anticoagulant) significantly reduced the incidence of equine herpesvirus Myeloencephalopathy (EHM), the severe neurologic form of EHV-1 β and improved survival during naturally occurring outbreaks.
Looking back at a real-world EHV-1 outbreak, the team found that horses treated with the combination therapy had dramatically better outcomes than those who didn't receive it, including several EHM-affected horses that survived and returned to work.
This is exactly the kind of applied outbreak-informed research that keeps the Marion duPont Scott Equine Medical Center at the forefront of equine infectious disease medicine β turning real clinical challenges into treatment protocols that protect horses everywhere.
