17 A. Z. Durrani S . M. Goyal Journal of Animal and Plant Sciences JAPS 20112011/02/01 21 1 NA 1018-7081 NA <p>To determine the seroprevalence of&nbsp;<em>Borrelia burgdorferi</em>&nbsp;in horses in Minnesota, the database of the Veterinary Diagnostic Laboratory, University of Minnesota, was searched over a ten year period (2001- May 2010). A total of 1,260 equine serum samples submitted by 112 veterinary clinics were tested using an indirect fluorescent antibody test. Samples with titers of&nbsp;<u>&gt;</u>1:320 were considered positive. The average rate of seroprevalence was 58.7% indicating high exposure of horses to&nbsp;<em>B</em><em>.</em><em>&nbsp;burgdorferi&nbsp;</em>in Minnesota. Our results indicate that Borreliosis should be considered as a differential in cases of horses with undiagnosed musculoskeletal or neurologic disease.</p> Lyme borreliosis, Horses, Borrelia burgdorferi, IFA test.
