ABSTRACT: The study of the viral component of ancient microbial communities from permafrost is important for the understanding evolution of microbial communities, possibility of their variations due to climate change, changes in the physical-chemical state of permafrost and practical questions of biosafety. For the first time the virus particles in native samples of ancient ice wedges of the Mammoth Mountain in Siberia have been discovered. Defined morphological diversity of viruses that can be attributed to five main types: miovirus, sifovirus, podovirus, spherical and filamentous. Specific characteristic of these viruses are small size and fever genome.

RÉSUMÉ: L™étude des virus qui sont présents dans des communautés microbiennes anciennes du pergélisol est cruciale pour la compréhension des questions fondamentales telles que l™évolution des communautés microbiennes, la possibilité de leur changement suite aux changements du climat, de l™état physico-chimique du pergélisol aussi bien que les questions pratiques concernant la sécurité biologique. Les virus ont été découverts pour la première fois dans des glaces éternelles de la montagne Mammouth. La définition de leur diversité morphologique faite, les virus peuvent être classés en cinq types principaux : miovirus, sifovirus, podovirus, virus sphériques et virus filamenteux. Leur spécificité consiste en une petite taille du génome.
