ABSTRACT
To determine the seroprevalence of Borrelia burgdorferi 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 >1:320 were considered positive. The average rate of seroprevalence was 58.7% indicating high
exposure of horses to B. burgdorferi in Minnesota. Our results indicate that Borreliosis should be considered as a
differential in cases of horses with undiagnosed musculoskeletal or neurologic disease.
Key words: Lyme borreliosis, Horses, Borrelia burgdorferi, IFA test.
