The horse is an incidental host for Lyme borreliosis. Although frequently considered the host for the spirochete, deer are a dead end host, showing no apparent clinical signs and not acting as a reservoir for further infection of ticks. They do act as a reservoir for the tick themselves though. In horses, well-documented clinical signs of Lyme borreliosis include neuroborreliosis, uveitis, and cutaneous lymphoma. Horses with neuroborreliosis may exhibit any of the following clinical signs: atrophy of spinal muscles, dysphagia, laryngeal dysfunction, facial paresis, spinal cord ataxia and paresis, behavioral changes, and hyperesthesia. Morbidity after B. burgdorferi infection in horses is unknown.

The first report of horses carrying antibodies to the organism causing Lyme Disease, Borrelia burgdorferi, appeared in the scientific literature 35 years ago. Neuroborreliosis in horses. Research at the Animal Health Diagnostic Center has shown that the Lyme multiplex assay can identify antibodies to B. burgdorferi in cerebrospinal fluid (CSF) to confirm neuroborreliosis in horses11 and to distinguish it from other causes of neurologic disease. How can I protect my horse from lyme disease?

2001). Most horses that are seropositive to B. burgdorferi never showed symptoms of Lyme disease or were so mild that they were not diagnosed. The best characterized signs of Lyme disease are neuroborreliosis and uveitis, which are compatible with late dissemination signs that in humans generally occur months to years after the initial infection.

We report herein a case of neuroborreliosis in a CVID horse, confirmed by combined immunologic testing, histopathology, real-time PCR assay, fluorescent in situ hybridization, and immunohistochemical staining.

Neuroborreliosis is still difficult to diagnose in horses. Clinical signs of neurologic disease in horses housed in an endemic area may increase suspicion, but the diagnosis requires confirmation by detection of antibodies to Borrelia burgdorferi or pathogen in the cerebrospinal fluid (CSF).
