Electron microscopic studies of the viruses in two hot springs (85 degrees C, pH 1.5-2.0, and 75-93 degrees 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.
对黄石国家公园两个温泉（85摄氏度，pH值1.5 - 2.0，以及75 - 93摄氏度，pH值6.5）中的病毒进行的电子显微镜研究发现了具有十二种不同形态类型的颗粒。这种多样性包括嗜热古菌的已知病毒、丝状脂毛病毒科、杆状鲁迪病毒科和纺锤状梭形病毒科，以及以前在自然界中未观察到的新形态类型。两种病毒类型类似于长尾噬菌体科和短尾噬菌体科的头尾噬菌体，这是在热液环境中首次观察到这些病毒。酸性温泉中的病毒宿主是嗜热古菌属嗜酸菌属的成员。
