Abstract

Electron microscopic studies of the viruses in two hot springs (85 °C, pH 1.5–2.0, and 75–93 °C, pH 6.5) in Yellowstone National Park revealed particles with twelve different morphotypes. This diversity encompassed known viruses of hyperthermophilic archaea, filamentous Lipothrixviridae , rod-shaped Rudiviridae , and spindle-shaped Fuselloviridae , and novel morphotypes previously not observed in nature. Two virus types resembled head-and-tail bacteriophages from the families Siphoviridae and Podoviridae , and constituted the first observation of these viruses in a hydrothermal environment. Viral hosts in the acidic spring were members of the hyperthermophilic archaeal genus Acidianus .
