Both of the horses were from Marquette County and were unvaccinated. The cases are as follows: a 25-year-old Quarter Horse gelding that developed a sudden onset of drooling, stumbling, blindness and seizures; and an 11-year-old Quarter Horse gelding from a different farm in Marquette County that was circling and stumbling. Both horses were euthanized. No quarantines were placed.
