Why virus taxonomy is important

The article, "Why virus taxonomy is important", published in Microbiology Today by Stuart Siddell, ICTV Vice President, discusses the importance of virus taxonomy and its role in helping to define the evolutionary relationships between viruses and understand the consequences of virus diversity.

ICTV in Nucleic Acids Research

An article appearing in the Nucleic Acids Research 2018 Database issue, "Virus taxonomy: the database of the International Committee on Taxonomy of Viruses (ICTV)" describes the ICTV database and the web-based tools available to query that database: Lefkowitz EJ, Dempsey DM, Hendrickson RC, Orton RJ, Siddell SG, Smith DB. Nucleic Acids Res. 2017 Oct 13. doi: 10.1093/nar/gkx932. PubMed PMID: 29040670.

The Virus Metadata Resource

The Virus Metadata Resource (VMR) is a downloadable spreadsheet that provides information on exemplar viruses for each species. This information includes GenBank and RefSeq accession numbers for exemplar viruses and isolate and common names for viruses belonging to a species.
