Observations on diagnostic tests for paratuberculosis in a deer herd
Journal of the American Veterinary Medical Association
|November 1, 1979
Summary
Paratuberculosis was diagnosed in fallow and sika deer at an Ohio animal park. Diagnostic tests, including fecal culture and immune response assays, were compared in affected deer.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Animal Health
Background:
- Paratuberculosis is a chronic infectious disease affecting ruminants.
- Deer populations in zoological settings can be susceptible to Johne's disease.
- Early diagnosis is crucial for herd management and disease control.
Purpose of the Study:
- To diagnose paratuberculosis in fallow and sika deer herds.
- To compare the efficacy of different diagnostic methods for paratuberculosis in deer.
- To evaluate delayed-type hypersensitivity and in vitro lymphocyte immunostimulation tests against fecal culture.
Main Methods:
- Diagnosis of paratuberculosis in a herd of fallow and sika deer.
- Collection of fecal samples for Mycobacterium paratuberculosis isolation.
- Performance of delayed-type hypersensitivity skin tests.
- In vitro lymphocyte immunostimulation assays.
Main Results:
- Paratuberculosis was confirmed in the deer herd.
- Comparative data on diagnostic test sensitivity and specificity were obtained.
- The study identified challenges in diagnosing paratuberculosis in this cervid population.
Conclusions:
- Paratuberculosis poses a diagnostic challenge in farmed deer.
- A combination of diagnostic approaches may be necessary for accurate detection.
- Further research is needed to optimize paratuberculosis diagnostics in cervids.
