Antibodies to Borrelia burgdorferi in New England horses: serologic survey.
Abstract: Twelve of 50 randomly selected horses from areas endemic for Borrelia burgdorferi had indirect fluorescent antibody titers of 1:8 to 1:2,048 against B burgdorferi. One of 50 horses from nonendemic areas had a titer of 1:8. This difference in the number of horses seropositive for B burgdorferi (P less than 0.002) and our finding that seropositive horses did not have agglutinating antibodies against potentially cross-reacting Leptospira spp indicated that horses in endemic areas were exposed to B burgdorferi and that the spirochete induced an antibody response in the horses.

The research article reports that some horses in Borrelia burgdorferi-infected areas of New England exhibited an immune response to the bacterium, while horses in non-endemic areas had very little exposure to the bacterium.
Objective of Research
- The main aim of this research was to study the prevalence and immune response of B. burgdorferi, the bacteria responsible for Lyme disease, in horses from endemic and non-endemic areas in New England.
Methodology and Approach
- A total of 50 horses each from both areas were randomly selected for this serologic survey.
- The team conducted the indirect fluorescent antibody test, a diagnostic method used to detect specific antibodies in the blood serum of the horses. This test measures the concentration of antibodies, known as titers.
Findings
- Out of the 50 horses selected from B. burgdorferi endemic areas, 12 had evidence of an immune response to the bacterium, with the antibody titers ranging from 1:8 to 1:2,048.
- Conversely, only one out of 50 horses sampled from non-endemic areas showed evidence of exposure to B. burgdorferi, with an antibody titer of 1:8. This significant difference emphasizes that horses in endemic areas are more likely to be exposed to the bacteria.
Significance of the Findings
- The researchers found that these seropositive horses did not carry agglutinating antibodies against Leptospira species, a bacteria group that could potentially cross-react and skew the results. This finding proves that the immune response seen in these horses was specifically due to B. burgdorferi.
- The results from this research highlight that horses in B. burgdorferi endemic areas are exposed to the bacterium, and being exposed, they develop an antibody response. This finding is significant as it suggests that horses may serve as a useful sentinel species for monitoring the prevalence and distribution of B. burgdorferi, and thus the risk of Lyme disease, in these regions.
