Wilke reverted a ViralQuest removal of Potexvirus from the dsDNA viruses, Family Polyomaviridae section. I am reversing that edit (and removing Genus Pomovirus) because these two genera are postive-strand ssRNA virus groups (not dsDNA). Genus Potexvirus is a member of the Family Flexiviridae and the Genus Pomovirus is an unassigned (+)ssRNA virus member. See said listings already in previous Virus Classification edits. See also:
ICTV Genus Potexvirus [1]
ICTV Genus Pomovirus [2]
ICTV Family Polyomaviridae [3] and

Thanks for allowing this edit. --ViralQuest 23:40, Nov 26, 2004 (UTC)
Possibly, although that's something for them to worry about. However, viruses are an odd case because they don't appear in the normal classification of living things. Kingdom Virus is rare, and Aphanobionta and Acyota are very obscure. More subtly, though, they shouldn't appear in the normal classification of living things because they don't form a phylogenetic hierarchy, and probably don't even have a single origin. So I'm not sure what we should do with them, but I'd say casually giving them a kingdom, domain, or empire isn't the solution. Josh
Though we wouldn't casually be giving them a kingdom/domain/empire. People already do that. A rankless taxobox would work as well, as anything above order is controversial, and they are all viruses, and the taxoboxes are nice to have on the virus pages. 132.205.15.43 05:38, 16 Dec 2004 (UTC)
A few people do that, but it is not very common, and I have not seen it done alongside three domains. As for the taxoboxes, I've moved my suggestion to Wikipedia talk:WikiProject Tree of Life. Josh
Do the numbers in the "Virus Family" column of the DNA Viruses and RNA Viruses tables mean anything, or are they just kind of there? (E.g. is Parvoviridae always DNA virus family number 3, by some authoritative source?) I'd suggest removing them if they're not meaningful, or explaining and citing a source if they are meaningful. -Agyle03:22, 20 September 2007 (UTC)[reply]
The abbreviation ICVCN (with piped link to this article) appears in the article Biology in the paragraph shown below, but does not appear here in this article.
Could this please be added in proper context so that people redirected here will find some material in context to satisfy them. AshLin04:29, 28 September 2007 (UTC)[reply]
I am fairly sure ICVCN refers to the ICTV's classification system, although I can't find a good, clearcut reliable statement relating the two. It seems like the code is informally referred to as "the ICTV code," "the ICTV database," and is formally cited as "The Seventh Report of the ICTV" or something, and that ICVCN is used rarely (perhaps more commonly around 1998-2000). Examples of dual usage this abstract, and this website. I'm hesitant to add info to either article clarifying this without an unambiguous citation. -Agyle18:29, 28 September 2007 (UTC)[reply]
Since the Code is now called "The International Code of Virus Classification and Nomenclature (ICVCN), March 2021 edition" on its own website and as now cited in the article, I believe that satisfies the requirement to explain the acronym :) Tony 1212 (talk) 17:06, 8 January 2024 (UTC)[reply]
It appears that the table under the RNA viruses heading is meant to list RNA viruses, but the Retroviridae are considered group VI in the Baltimore classification (whereas only groups III, IV, and V are listed as strictly RNA viruses here on this page). Should the Retroviridae be removed from the RNA virus table? Should the table include the Baltimore classifications?Scray (talk) 04:53, 11 April 2008 (UTC)[reply]
I don't really understand your question, but retroviruses eg HIV are RNA viruses. During replication they have a DNA intermediary, (pro-viral DNA), but they are RNA viruses nonetheless. GrahamColmTalk15:27, 11 April 2008 (UTC)[reply]
I checked out Scray's edit when it was made. He appears to be correct - see See Also link at bottom of page. In Baltimore's classification retroviruses belong to Group VI, and therefore don't belong in a list of taxa in Groups III-V. Lavateraguy (talk) 15:44, 11 April 2008 (UTC)[reply]
What is the basis for the 'virus family' classification in the table in this section?
There are seven 'families' which is confusing since they echo the seven groups under Baltimore. At least it's confusing to me as a non-taxonomist... For instance it sort of suggests the Hepadnaviridae/HBV ('family 6') are in Group VI. ICTV isn't very helpful (Hepadnaviridae are an unassigned family) but i've not come across this system before so i'd like to know more about it (although it seems coherent enough.) If it's just a listing of recognised families, would it be helpful to list their baltimore groups s well, to make it clear where they fit in the overall ICTV scheme? ditto the equivalent table under RNA viruses section.
The tables in the "Baltimore Classification" system appear to be from a different taxonomy. I was very confused when I found the "Hepatitis B" entry in what appeared to be the "Group II" table.
I attempted to unscrew this mess by adding a column to each table giving the Baltimore group, but if the tables are in fact from some othre taxonomy, they should be removed fromt h eBaltimore section and added to a new "comparison of classificatins" section. -Arch dude (talk) 13:52, 9 September 2008 (UTC)[reply]
This is an old document from 1996 based on the International Committee on Taxonomy of Viruses (ICTV) guidelines. Their current (2010) website is here [6]. Graham ColmTalk11:44, 6 February 2010 (UTC)[reply]
"Which are not yet definitively classified as living or non-living"
Under "ICTV classification" it says:
"Herpesvirales contain large eukaryotic dsDNA viruses."
Wouldn't it be better to say:
"Herpesvirales includes" (with an "s") "large dsDNA viruses which have eukaryotic hosts." - or something? -lifeform (talk) 03:59, 13 March 2016 (UTC)[reply]
So, how are viruses classified in the sense of organizing them into the ICTV hierarchy (realm, kingdom, phylum, and so on)? The article appears to say nothing at all on this subject. The Baltimore system is separate, and the LHT system appears to be an alternate system. — Preceding unsigned comment added by 2603:9000:AC08:A600:F9A2:D64C:B3D4:6FBF (talk) 00:36, 10 June 2020 (UTC)[reply]
Strains versus variants, strain and variant classification
"Par. 3.3: The ICTV is not responsible for classification and nomenclature of virus taxa below the rank of species. The classification and naming of serotypes, genotypes, strains, variants and isolates of virus species is the responsibility of acknowledged international specialist groups.
Comment: A variety of subspecific grouping may be identified within the members of a single virus species. These may be described as viruses with alternative names (e.g. blackeye cowpea mosaic virus and peanut stripe virus, which are both classified in the species Bean common mosaic virus, genus Potyvirus, family Potyviridae), or as serotypes, genotypes, clades, strains, variants, isolates etc. Naming of such entities is not the responsibility of the ICTV but of international specialty groups. It is the responsibility of ICTV Study Groups to consider how these entities may best be classified into species."
Strains are the same as variants and they are not classified. They just have a designation. Influenza virus variants are a good example; Diagram of influenza nomenclatureGraham Beards (talk) 14:27, 8 January 2021 (UTC)[reply]
Since the species concept *is* covered in the article, I have removed this template... I too had no idea to what it was referring. Tony 1212 (talk) 05:40, 6 January 2024 (UTC)[reply]
