and two
possible proviruses in the Methanococcus voltae A3 draft
genome sequence (Krupovic and Bamford, 2008). Nothing is
known of viruses of the extremely abundant mesophilic
Archaea that are present in soils and the oceans (reviewed in
Chaban et al. 2006). The long-awaited isolation of one of the
latter, Nitrosopumilus maritimus by Stahl and coworkers,
should allow screening to take place (Konneke et al. 2005).
