Hypothesis
Is there a breed predisposition for Borrelia burgdorferi infections in Bernese Mountain Dogs?
Conclusion
Bernese Mountain Dogs have a significantly higher prevalence of antibodies against B. burgdorferi compared to control dogs, suggesting a possible breed predisposition.
Supporting Evidence
- 58% of Bernese Mountain Dogs tested positive for B. burgdorferi antibodies.
- Only 15% of control dogs tested positive for the same antibodies.
- Significantly more Bernese Mountain Dog owners reported their dogs had attached ticks compared to control dog owners.
Takeaway
This study found that Bernese Mountain Dogs are more likely to have a certain infection compared to other dog breeds.
Methodology
The study assessed seroprevalence of B. burgdorferi using ELISA and Western blot in Bernese Mountain Dogs and control dogs.
Potential Biases
Owner-reported data on tick exposure may introduce bias.
Limitations
The study did not explore the biological reasons for the higher prevalence of antibodies in Bernese Mountain Dogs.
Participant Demographics
160 Bernese Mountain Dogs and 62 control dogs, with similar environments.
