Item Strengthening the interaction of the virology community with the International Committee on Taxonomy of Viruses (ICTV) by linking virus names and their abbreviations to virus species(Systematic Biology, 2019) Zerbini, Francisco Murilo; Calisher, Charles H.; Briese, Thomas; Brister, J. Rodney; Charrel, Rémi N.; Dürrwald, Ralf; Ebihara, Hideki; Fulhorst, Charles F.; Gāo, George Fú; Groschup, Martin H.; Haddow, Andrew D.; Hyndman, Timothy H.; Junglen, Sandra; Klempa, Boris; Klingström, Jonas; Kropinski, Andrew M.; Krupovic, Mart; et al.The International Committee on Taxonomy of Viruses (ICTV) is tasked with classifying viruses into taxa (phyla to species) and devising taxon names. Virus names and virus name abbreviations are currently not within the ICTV’s official remit and are not regulated by an official entity. Many scientists, medical/veterinary professionals, and regulatory agencies do not address evolutionary questions nor are they concerned with the hierarchical organization of the viral world, and therefore, have limited use for ICTV-devised taxa. Instead, these professionals look to the ICTV as an expert point source that provides the most current taxonomic affiliations of viruses of interests to facilitate document writing. These needs are currently unmet as an ICTV-supported, easily searchable database that includes all published virus names and abbreviations linked to their taxa is not available. In addition, in stark contrast to other biological taxonomic frameworks, virus taxonomy currently permits individual species to have several members. Consequently, confusion emerges among those who are not aware of the difference between taxa and viruses, and because certain well-known viruses cannot be located in ICTV publications or be linked to their species. In addition, the number of duplicate names and abbreviations has increased dramatically in the literature. To solve this conundrum, the ICTV could mandate listing all viruses of established species and all reported unclassified viruses in forthcoming online ICTV Reports and create a searchable webpage using this information. The International Union of Microbiology Societies could also consider changing the mandate of the ICTV to include the nomenclature of all viruses in addition to taxon considerations. With such a mandate expansion, official virus names and virus name abbreviations could be catalogued and virus nomenclature could be standardized. As a result, the ICTV would become an even more useful resource for all stakeholders in virology.Item Changes to taxonomy and the International Code of Virus Classification and Nomenclature ratified by the International Committee on Taxonomy of Viruses (2018)(Archives of Virology, 2018-05-12) Zerbini, Francisco Murilo; King, Andrew M. Q.; Lefkowitz, Elliot J.; Mushegian, Arcady R.; Adams, Michael J.; Dutilh, Bas E.; Gorbalenya, Alexander E.; Harrach, Balázs; Harrison, Robert L.; Junglen, Sandra; Knowles, Nick J.; Kropinski, Andrew M.; Krupovic, Mart; Kuhn, Jens H.; Nibert, Max L.; Sabanadzovic, Sead; Rubino, Luisa; et al.This article lists the changes to virus taxonomy approved and ratified by the International Committee on Taxonomy of Viruses in February 2018. A total of 451 species, 69 genera, 11 subfamilies, 9 families and one new order were added to the taxonomy. The current totals at each taxonomic level now stand at 9 orders, 131 families, 46 subfamilies, 803 genera and 4853 species. A change was made to the International Code of Virus Classification and Nomenclature to allow the use of the names of people in taxon names under appropriate circumstances. An updated Master Species List incorporating the approved changes was released in March 2018Item Virus taxonomy in the age of metagenomics(Nature Reviews Microbiology, 2017-03) Simmonds, Peter; Adams, Mike J.; Benko, Mária; Breitbart, Mya; Brister, J. Rodney; Zerbini, F. Murilo; Carstens, Eric B.; Davison, Andrew J.; Delwart, Eric; Gorbalenya, Alexander E.; Harrach, Balázs; Hull, Roger; King, Andrew M.Q.; Koonin, Eugene V.; Krupovic, Mart; Kuhn, Jens H.; Lefkowitz, Elliot J.; et al.The number and diversity of viral sequences that are identified in metagenomic data far exceeds that of experimentally characterized virus isolates. In a recent workshop, a panel of experts discussed the proposal that, with appropriate quality control, viruses that are known only from metagenomic data can, and should be, incorporated into the official classification scheme of the International Committee on Taxonomy of Viruses (ICTV). Although a taxonomy that is based on metagenomic sequence data alone represents a substantial departure from the traditional reliance on phenotypic properties, the development of a robust framework for sequence-based virus taxonomy is indispensable for the comprehensive characterization of the global virome. In this Consensus Statement article, we consider the rationale for why metagenomic sequence data should, and how it can, be incorporated into the ICTV taxonomy, and present proposals that have been endorsed by the Executive Committee of the ICTV.
