Abstract
SUMMARY: From October 1982 to May 1984, we studied 34 dogs from the Lyme, Conn area that had a history of tick exposure and lameness associated with pain, warmth, and/or swelling in one or more joints. Large numbers of polymorphonuclear leukocytes were seen in Giemsa-stained smears of synovial fluid from 9 dogs, and spirochetes (Borrelia burgdorferi) were found in 1 sample by darkfield microscopy and immunoperoxidase techniques. The geometric mean antibody titer to B burgdorferi in the 34 dogs was 1:2,700, compared with 1:285 in 43 clinically normal dogs from the same area (PPB burgdorferi in dogs may cause arthritis similar to that in human Lyme disease.
