Plain-English summary

A horse with acute encephalitis showed symptoms like a mild fever, difficulty walking, a head tilt, and circling behavior. Tests revealed that the horse had a significant immune response to a virus known as the snowshoe hare virus, which is usually associated with humans. The veterinarian treated the horse with antibiotics, steroids, and vitamins, and fortunately, the horse made a full recovery.

Abstract

A 4-fold or greater seroconversion to the snowshoe hare serotype of the California serogroup of viruses in a horse with acute encephalitis was demonstrated by hemagglutination-inhibition, complement-fixation, and neutralization tests. The horse had a mild fever, was ataxic, had a head tilt, and was observed to circle. Chloramphenicol, dexamethasone, and B complex vitamins were administered and the horse recovered. The snowshoe hare virus is a recognized human pathogen, but it has not been associated with disease in horses. It is unknown whether horses play a role as amplification hosts for the snowshoe hare virus in nature, and further studies appear indicated.
