Photos of Naegleria fowleri

A cytospin of fixed CSF showing a Naegleria fowleri trophozoite (arrow) stained with Giemsa-Wright amidst polymorphonuclear leukocytes and a few lymphocytes. Within the trophozoite, the nucleus and nucleolus can be seen. Magnification: 1000x.

A section of the cerebral portion of the brain from a PAM patient, stained with hematoxylin and eosin, showing large clusters of Naegleria fowleri trophozoites and the destruction of the normal brain tissue architecture. Cysts are not seen. Magnification: 100x. Inset: Higher magnification (1000x) of Naegleria fowleri trophozoites (arrows) with the characteristic nuclear morphology.

Cysts are not seen. Magnification: 100x. Inset: Higher magnification (1000x) of Naegleria fowleri trophozoites (arrows) with the characteristic nuclear morphology.

A section of the cerebral portion of the brain from a PAM patient reacted with the specific anti-Naegleria fowleri antibody which has been conjugated to a fluorescent antibody (immunofluorescent staining) viewed using microscopy with an exciter filter. Note the large numbers of Naegleria fowleri trophozoites staining bright green. No cysts are seen. Magnification: 100x.
