RESUMO

Mice challenged intranasally with Naegleria fowleri died of primary amoebic meningoencephalitis. Mice given 30 mg of cyclophosphamide per kg of body weight daily for 10 days starting 2 days before challenge were protected. Neither cyclophosphamide nor serum from cyclophosphamide-treated mice inhibited N. fowleri in vitro. A metabolic product of cyclophosphamide, acrolein, inhibited growth and enflagellation of N. fowleri. Acrolein at 40 microM was amoebicidal. Acrolein injured starved cells and amoebae at 5 degrees C and growing N. fowleri.
