Abstract

During a study of the extremely thermophilic bacteria of Yellowstone, we became aware of the published report (Scaglia et al., 1983) of the isolation of a thermophilic amoeba (Naegleria australiensis) from the bathing pools of a commercial Italian hot spring spa and their observation that some of these newly isolated amoebae strains were as virulent for mice as Naegleria fowleri, the etiological agent of primary amoebic meningoencephalitis in humans (John, 1982; Marciano-Cabral, 1988). Because of the possibility that similar types of thermophilic pathogenic amoebae might be present in the Yellowstone and Grand Teton National Park thermal areas and possible exposure to park visitors and employees, we conducted a survey for Naegleria isolates, concentrated on those pools or outflows where it was known that visitors and employees used these pools for unauthorized bathing and soaking (Whittley, 1995).
