Spiraviridae is a family of viruses that replicate in hyperthermophilic archaea of the genus Aeropyrum, specifically Aeropyrum pernix. The family contains one genus, Alphaspiravirus, which contains one species, Aeropyrum coil-shaped virus. The virions of Aeropyrum coil-shaped virus (ACV) are non-enveloped and in the shape of hollow cylinders that are formed by a coiling fiber that consists of two intertwining halves of the circular DNA strand inside a capsid. An appendage protrudes from each end of the cylindrical virion. The viral genome is positive-sense, single-stranded DNA ((+)ssDNA) and encodes for significantly more genes than other known ssDNA viruses. ACV is also unique in that it appears to lack its own enzymes to aid replication, instead likely using the host cell's replisomes. A

| - Spiraviridae ist die Bezeichnung für eine Familie (Biologie) von Viren, die sich hyperthermophilen Archaeen der Gattung ([en], Crenarchaeota) replizieren (vermehren), insbesondere der Spezies .Die Virusfamilie enthält gemäß International Committee on Taxonomy of Viruses (ICTV) nur derzeit (Stand Anfang Februar 2021) eine Gattung, Alphaspiravirus, die wiederum nur eine Spezies, Aeropyrum-coil-shaped-Virus (offiziell Aeropyrum coil-shaped virus, ACV), enthält. Auch beim National Center for Biotechnology Information (NCBI) sind bis dato keine weiteren Mitglieder der Familie als vorgeschlagen bekannt, die Familie ist daher in dieser Spezies monotypisch. Der Grund ist, dass ACV keine bekannte Verwandtschaft mit anderen Archaeen-infizierenden Viren hat. Es teilt lediglich seine spiralförmige Morphologie mit einigen anderen Archaeen-Viren. Dies deutet darauf hin, dass es sich hier möglicherweise um eine sehr alte Linie von Viren handelt, die nur Archaeen infizieren. Der Name der Familie und Gattung leitet sich ab von lateinisch spira ‚Spule‘ in Anlehnung an die Form der Virionen (s. u.). (de)

ACV is also unique in that it appears to lack its own enzymes to aid replication, instead likely using the host cell's replisomes. ACV has no known relation to any other archaea-infecting viruses, but it does share its coil-like morphology with some other archaeal viruses, suggesting that such viruses may be an ancient lineage that only infect archaea.
