The brain-eating amoeba: Naegleria fowleri

Abstract

Naegleria fowleri or the “brain-eating amoeba,” is a microorganism that inhabits warm waters. This amoeba can enter the human body, invade the brain, and cause primary amebic meningoencephalitis, a lethal infection with a mortality rate higher than 98%. Although the presence of this and other potentially pathogenic amoebae has been reported throughout Mexico, only a few medical cases have been documented. Nevertheless, it is essential to prevent contact, mainly by avoiding swimming in contaminated waters, keeping swimming pools properly chlorinated, using nasal plugs, and promoting awareness campaigns. Since no effective treatment currently exists, prevention remains the best strategy.
