Neoplasms in Tasmanian devils (Sarcophilus harrisii).
Journal of the National Cancer Institute
|March 1, 1979
Summary
Pathologic studies on 18 Tasmanian devils revealed spontaneous neoplasms and proliferative lesions as the most common diseases. Many devils exhibited multiple concurrent conditions, including renal disease, highlighting significant health challenges in the species.
Area of Science:
- Veterinary Pathology
- Wildlife Disease Ecology
- Conservation Medicine
Background:
- Tasmanian devils (Sarcophilus harrisii) face conservation challenges.
- Understanding disease prevalence is crucial for species management.
- Pathologic data from zoological populations can inform wild population health.
Purpose of the Study:
- To document the spectrum and frequency of diseases in a cohort of Tasmanian devils.
- To identify common pathologic conditions, including neoplasms and hyperplasia.
- To assess the occurrence of multiple, concurrent diseases.
Main Methods:
- Necropsy examinations were performed on 18 deceased Tasmanian devils.
- Histopathologic evaluation of tissues was conducted.
- Disease diagnoses were recorded and categorized.
Main Results:
- Spontaneous neoplasms and preneoplastic hyperplasia were the most frequent diseases observed.
- Abnormal proliferative lesions were identified in 9 out of 18 devils.
- Six devils presented with two or more co-existing proliferative diseases; 7 had renal disease.
Conclusions:
- Tasmanian devils are prone to spontaneous neoplasms and proliferative lesions.
- The high incidence of multiple, concurrent diseases suggests complex disease interactions.
- Renal disease is also a significant health concern in this population.
