ICTV Virus Taxonomy Profile: Spiraviridae

Prangishvili, David | Mochizuki, Tomohiro | Krupovic, Mart | Report Consortium, Ictv

International audience. The family Spiraviridae includes viruses that replicate in hyperthermophilic archaea from the genus Aeropyrum. The non-enveloped, hollow, cylindrical virions are formed from a coiling fibre that consists of two intertwining halves of a single circular nucleoprotein filament. A short appendage protrudes from each end of the cylindrical virion. The genome is circular, positive-sense, single-stranded DNA of 24 893 nucleotides. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) report on the family Spiraviridae, which is available at ictv.global/report/spiraviridae.

ICTV Virus Taxonomy Profile: Tristromaviridae

Archive ouverte | Prangishvili, David | CCSD

International audience. Tristromaviridae is a family of viruses with linear, double-stranded DNA genomes of 16-18 kbp. The flexible, filamentous virions (400±20 nm×30±3 nm) consist of an envelope and an inner core c...
