🔬CSF (cerebrospinal fluid) examination.
✅Naegleria fowleri trophozoites in cerebrospinal fluid in primary amoebic meningoencephalitis (PAM). Note the pale nucleus with a large karyosome (arrow) (Giemsa; 1000×).
✅The parasite lives in warm water with temperatures ranging from 25 °C to 32 °C. During swimming, the parasite enters the nose, then the olfactory nerve. Along the nerve, the parasite reaches the brain. To avoid the disease, one should not come into contact with dirty water or swim in it.
