About The Presenters

Both Sellon and Long have spent a lot of time researching and treating horses with West Nile virus, and they offer a special insight on this disease that crosses all breeds, disciplines, ages, and sexes of horses.

Dr. Sellon's primary research interests are in the fields of infectious disease, hematology, and pain management. She is currently investigating the pathogenesis of disease in horses infected with Sarcocystis neurona, the most common cause of equine protozoal myeloencephalitis. She's also investigating ways to more adequately manage pain in horses that have undergone abdominal surgery. Dr. Sellon frequently serves as an invited speaker at national and international equine veterinary clinical and research symposia.

Dr. Maureen Long received her DVM from Iowa State University in 1986, after which she was in private practice with Dr. Martin Simenson at Suffolk Downs Racetrack in Massachusetts, with Peter Schaad at Rockingham Park in New Hampshire, then at Andover Ambulatory Clinic in Massachusetts. She completed a residency in large animal internal medicine at the University of Illinois in 1993, when she also received a Master of Science degree. From 1993-1998 she was a resident in the Department of Veterinary Microbiology and Immunology at Washington State University, from which she received her PhD in 1998.

During her research training programs, she received several research awards. After receiving her PhD, she was an assistant professor at Washington State University until she joined the faculty of the University of Florida College of Veterinary Medicine in the Department of Large Animal Clinical Sciences in May 1999. Dr. Long is a Diplomate of the American College of Veterinary Internal Medicine. Her clinical interests are infectious diseases, immunology, and endocrine diseases. Her research interests include several equine and large animal infectious diseases, including Ehrlichia risticii, Neospora caninum, Toxoplasma gondii, equine infectious anemia virus, and West Nile virus. She is frequently invited to speak at national and international equine veterinary clinical and research symposia.
