title: Arthritis and panuveitis as manifestations of Borrelia burgdorferi infection in a Wisconsin pony.
abstract: Infection with Borrelia burgdorferi caused panuveitis and arthritis in a pony. Spirochetes were detected by direct immunofluorescence in the anterior chamber of the eye. The carpal joints had severe degenerative joint disease, with synovial proliferation. The synovium and serum had B burgdorferi antibody titers of 1:1024. The pony lived in an area of Wisconsin where infection with B burgdorferi is endemic in human beings. Previously, serum antibodies to B burgdorferi had been found in horses, but disease had not been reported.
