Brain-eating amoeba. A free-living microbe that can cause fatal PAM in warm freshwater.
An eight-year-old girl from Ruston, Louisiana, has died after contracting Naegleria fowleri, a rare brain-eating amoeba found in warm freshwater. Officials say exposure most likely occurred at Lake Claiborne during summer; the infection is nearly always fatal. Authorities stress caution for swimmers and nose-clipping to reduce risk.
