title: Isolation of Equine rhinitis A virus from a horse semen sample.
abstract: Semen from an apparently healthy 4-year-old American Quarter Horse was submitted to the National Veterinary Services Laboratories for Equine arteritis virus isolation. Visual inspection of the semen sample upon arrival noted it was unusually yellow in color. The semen sample was inoculated onto cell monolayers, and cytopathic effect was observed 5 days postinoculation. The resultant isolate tested negative for Equine arteritis virus, and was subsequently identified as Equine rhinitis A virus. Equine rhinitis A virus has been isolated from horse urine, but has not been described in stallion semen. The present study documents the isolation of Equine rhinitis A virus from stallion semen that was likely contaminated with urine at the time of collection.
