QUESTION
“Mad cow disease” is caused by?
OPTIONS
(A) Rabies virus
(B) Mycoplasma
(C) Chlamydia
(D) None of the above
ANSWER
(D) None of the above
EXPLANATION
Mad cow disease, or bovine spongiform encephalopathy, is caused by a misfolded infectious prion protein rather than a conventional virus, bacterium, or chlamydial organism. Therefore option D, 'None of the above,' is correct; rabies virus causes rabies, whereas Mycoplasma and Chlamydia are bacteria-like organisms and do not cause BSE.
