Phages are the most abundant organisms in the biosphere and they are a ubiquitous feature
of prokaryotic existence. A bacteriophage is a virus which infects a bacterium. Archaea are …

“Phages” include viruses of eubacteria and archaea. At least 5568 phages have been
examined in the electron microscope since the introduction of negative staining in 1959 …

One of the most prominent features of archaea is the extraordinary diversity of their DNA
viruses. Many archaeal viruses differ substantially in morphology from bacterial and …

The adaptive immune CRISPR/Cas and CRISPR/Cmr systems of the crenarchaeal
thermoacidophile Sulfolobus were challenged by a variety of viral and plasmid genes, and …

DNA viruses of the Archaea have highly diverse and often exceptionally complex
morphotypes. Many have been isolated from geothermally heated hot environments, raising …

Clusters of regularly spaced direct repeats, separated by unconserved spacer sequences,
are ubiquitous in archaeal chromosomes and occur in some plasmids. Some clusters …

In contrast with former definitions of life limited to membrane-bound cellular life forms which
feed, grow, metabolise and replicate (i) a role of viruses as genetic symbionts,(ii) along with …

Spindle-or lemon-shaped viruses infect archaea in diverse environments. Due to the highly
pleomorphic nature of these virions, which can be found with cylindrical tails emanating from …

This review presents a personal account of research on archaeal viruses and describes
many new viral species and families, demonstrating that viruses of Archaea constitute a …

Thermophilic viruses were reported decades ago; however, knowledge of their diversity,
biology, and ecological impact is limited. Previous research on thermophilic viruses focused …
