Hypothesis
Can kidneys of scrapie-affected sheep accumulate pathological prion protein (PrPSc)?
Conclusion
The study found significant levels of PrPSc in the kidneys of scrapie-affected sheep, indicating a potential pathway for prion transmission.
Supporting Evidence
- 73.6% of clinically scrapie-affected sheep showed PrPSc in their kidneys.
- PrPSc was detected in kidneys of subclinical sheep, but at lower levels.
- Kidneys from control sheep were devoid of PrPSc.
Takeaway
This study shows that sick sheep can have bad proteins in their kidneys, which might help spread the disease to other sheep.
Methodology
The study involved screening kidneys from naturally and experimentally scrapie-affected sheep using Western blot and immunohistochemistry.
Potential Biases
Potential bias in sample selection from specific geographical regions.
Limitations
The study primarily focused on Sarda sheep and may not be generalizable to other breeds.
Participant Demographics
Sheep from distinct flocks in Sardinia and Abruzzo, Italy, including both clinically affected and control groups.
