A novel virus, termed Pyrobaculum spherical virus (PSV), is described that infects anaerobic hyperthermophilic archaea of the genera Pyrobaculum and Thermoproteus. Spherical enveloped virions, about 100 nm in diameter, contain a major multimeric 33-kDa protein and host-derived lipids. A viral envelo...
