Cerebrospinal fluid centrifuge analysis in primary amebic meningoencephalitis due to Naegleria fowleri.

We describe a case of primary amebic meningoencephalitis due to Naegleria fowleri. This is the first reported case, to our knowledge, in Missouri. Emphasis is placed on the morphologic identification of degenerating amebas in a cytospin preparation of cerebrospinal fluid using Wright's stain during the rapidly progressive meningoencephalitic stage.
