Which of the following is the causative agent of primary amoebic meningoencephalitis?
- A. Naegleria fowleri
- B. Entameba histolyticum
- C. Amoeba proteus
- D. Acanthamoeba polyphaga
Correct Answer: A
Rationale: The correct answer is A: Naegleria fowleri. This is because Naegleria fowleri is known to be the causative agent of primary amoebic meningoencephalitis, a rare but serious infection of the brain. This amoeba enters the body through the nasal passages and travels to the brain, causing inflammation and damage. Entameba histolyticum is a different species of amoeba that causes amoebiasis, a gut infection. Amoeba proteus is a harmless freshwater amoeba used in biology studies. Acanthamoeba polyphaga can cause infections in immunocompromised individuals but is not associated with primary amoebic meningoencephalitis.
