INTERIM REPORT FROM USA – February 2003
Outbreak of EHV-1 Neurological Disease.
Towards the end of January 2003, riding horses at the equestrian
facility of the University of Findlay, in north west Ohio experienced clinical
signs consistent with the neurological form of equine herpes virus. The neurological
signs were preceded by fever, nasal discharge and edema of the limbs in many
of the 135 horses stabled at the facility. As of February 3, 12 of 30 clinically
affected animals have been euthanized.
Investigations undertaken by veterinarians at the University in conjunction with the Ohio Department of Agriculture Animal Disease Diagnostic Laboratory and Ohio State University College of Veterinary Medicine identified the causal agent as EHV-1 by PCR and DNA sequencing. Blood samples received by Dr. George Allen, at the Maxwell H. Gluck Equine Research Center of the University of Kentucky during the last week of January confirmed the presence of EHV-1 by virus isolation allowing further characterization by molecular and serological typing.
The equestrian facility has been placed under strict voluntary isolation with no movement of horses either into or out of the facility.
