2015 ACVIM Forum Research Abstract Program

While all facets of the patient's history, physical and neurological examinations, and diagnostic proceedings should be carefully reviewed when prognosticating functional outcome, no single factor can be definitely utilized to determine which deep pain negative patients will recover. Furthermore, all clients should be informed that return of deep pain perception does not guarantee the return of voluntary urination, which is likely a more important consideration for long term management. Serological analysis indicates that infection of horses with Borrelia burgdorferi is common. However, diagnosis of equine Lyme neuroborreliosis (LNB) is rare, with limited description in the literature. This retrospective study provides a detailed description of clinical and diagnostic data from horses with a histologic diagnosis of LNB.
