The two mares aborted during their ninth and tenth month of pregnancy. One week prior to the abortions, two horses on the same farm suddenly developed neurological signs consistent with the neurological form of EHV-1 infection. These horses were euthanased and no further diagnostic testing was performed. The farm owner has voluntarily placed the premises under quarantine to reduce the risk of disease transmission.
