Question:
Bovine spongiform encephalopathy disease is caused by:
Bovine spongiform encephalopathy disease is caused by:
Show Hint
Prions = Infectious proteins (no DNA/RNA) → cause neurodegenerative diseases.
Updated On: Jun 19, 2026

- Bacteria
- Virus
- Prions
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Disease understanding.
Bovine spongiform encephalopathy (mad cow disease) is a neurodegenerative disease affecting cattle.
Step 2: Causative agent.
It is caused by prions, which are misfolded infectious proteins.
Step 3: Unique nature of prions.
Unlike viruses or bacteria, prions contain no nucleic acid and propagate by inducing misfolding of normal proteins.
Step 4: Final conclusion.
Thus, BSE is caused by prions.
Final Answer: \[ \boxed{\text{Prions}} \]
