abstract

A survey was designed to know the Concentration of Naegleria fowleri in recreational areas in Hornos, Sonora, during a year. Samples were taken monthly at La Isleta and Las Palmas and the total amoeba counts were obtained by the most probable number method (MPN). The identification of N. fowleri was made by PCR. The maximum concentration of total thermophilic amoebae was 9175 MPN/L for La Isleta and 3477 MPN/L for Las Palmas. Thermophilic Naegleria were present mainly during summer and fall. October's concentrations were up to 201 MPN/L, at both places. The maximum concentrations of N. fowleri were 201 MPN/L and 18 MPN/L for La Isleta and Las Palmas respectively, and were isolated from August to October. The presence of N. fowleri in these particular natural bodies of water reinforces the need for adaptation of preventive measures to avoid cases of primary amoebic meningoencephalitis.
