Rafaela De Negri, DVM, MS, said that when the opportunity arose to come to Kentucky, she couldn’t resist. The equine caseload at UK’s Veterinary Diagnostic Laboratory gave her the opportunity to study a collection of equine diseases she wouldn’t be able to see anywhere else in the world.

“During my pathology residency, I became more engaged in veterinary sciences and my interest in infectious diseases grew stronger,” she said. “This led me to pursue a master’s degree with Dr. John Timoney (MVB, PhD, DSc, MRCVS), a renowned scientist and professor in equine infectious diseases at the Gluck Center."

Streptococcus infections are important to the horse industry worldwide because they can cause large outbreaks and severe disease in horse populations. There are two key pathogenic bacterial species of Streptococcus in horses: S. equi and S. zooepidemicus.

De Negri has investigated differences in equine serum antibody responses to these two bacterial infections. S. equi, the causative agent of strangles, is highly contagious and horses can be carriers and shed the bacteria, although they might show no outward clinical signs.
