How to write species and virus names

The ICTV's recommendation for how to write species and virus names. (Updated May 28, 2019)

  • Eduardo,

    You are correct. The use of capitalization and italics as indicated in the article above, is meant for official, ICTV-approved taxon names. Proposed, but not yet approved taxon names should be written as per the guidelines above for writing virus names.

    Best regards,


  • Dear ICTV members,

    I have a doubt.

    Recently, in an article entitled "A major lineage of non-tailed dsDNA viruses as unrecognized killers of marine bacteria", published online on 24 January 2018, as a Letter in Nature, the authors propose the name of a new family, named Autolykiviridae. In their article, authors uses the name Autolykiviridae in italics for define it as a possible new virus family. Is right to use Autolykiviridae in italics in this case, even when this "new family" is not yet recognized by the ICTV?

    Best regards,
