Fungi from geothermal soils in Yellowstone National Park

Article Abstract:

Fungi from Yellowstone National Park geothermal soils near Amphitheater Springs have been studied. Temperatures in the soils were as high as 70 degrees Celsius with low pH values, high heavy metal content, sparse vegetation and little organic carbon, yet 16 fungal species were cultured, of which two were thermophilic and six thermotolerant. From nearby soils with normal temperatures, 0-22 degrees Celsius, only three of the species were cultured. Optimal in vitro growth conditions and temporal and spatial distribution were investigated.

Legionella species diversity in an acidic biofilm community in Yellowstone National Park

Article Abstract:

The predominately eukaryotic algal mat community in a pH 2.7 geothermal stream in Yellowstone National Park for the presence of Legionella and potential host amoebae is investigated. The Legionella species frequently detected in aquatic environments are cultured and sequenced partial 18s rRNA gene regions from two potential hosts, Acanthamoeba and Euglena species.

PCR detection and analysis of the free-living amoeba Naegleria in hot springs in Yellowstone and Grand Teton National Parks

Article Abstract:

Three previously unknown free-living amoeba Naegleria species are detected in a survey of 23 hot springs in Yellostone and Grand Trenton National Parks as determined by polymerase chain reaction (PCR) probes specific for Naegleria. Research also reveals a fourth pathogenic N. fowleri.
