Virus taxonomy: the database of the International Committee on Taxonomy of Viruses (ICTV)

Abstract

The International Committee on Taxonomy of Viruses (ICTV) is charged with the task of developing, refining, and maintaining a universal virus taxonomy. This task encompasses the classification of virus species and higher-level taxa according to the genetic and biological properties of their members; naming virus taxa; maintaining a database detailing the currently approved taxonomy; and providing the database, supporting proposals, and other virus-related information from an open-access, public web site. The ICTV web site (http://ictv.global) provides access to the current taxonomy database in online and downloadable formats, and maintains a complete history of virus taxa back to the first release in 1971. The ICTV has also published the ICTV Report on Virus Taxonomy starting in 1971. This Report provides a comprehensive description of all virus taxa covering virus structure, genome structure, biology and phylogenetics. The ninth ICTV report, published in 2012, is available as an open-access online publication from the ICTV web site. The current, 10th report (http://ictv.global/report/), is being published online, and is replacing the previous hard-copy edition with a completely open access, continuously updated publication. No other database or resource exists that provides such a comprehensive, fully annotated compendium of information on virus taxa and taxonomy.

Detection and genotyping of enteric viruses in hospitalized children with acute gastroenteritis in Belém, Brazil: Occurrence of adenovirus viremia by species F, types 40/41

“…AdV are associated with various morbid diseases, such as gastroenteric, respiratory, and ocular diseases (mainly conjunctivitis). Types 40 and 41, both from species F, are the main responsible for both isolated episodes and outbreaks of gastroenteritis, which predominantly affect children . Types 40 and 41 have already been established as the primary pathogens responsible for nosocomial infection in both normal and immunosuppressed individuals, which could be caused by a clinical condition or acquired from organ transplantation …”

“…In particular, HAstV has been reported to account for up to 10% of sporadic cases of nonbacterial diarrhea . On the basis of the complete sequence of the capsid or open reading frame 2 (ORF2) region, HAstV are classified into eight classic types (HAstV‐1 to HAstV‐8), the MAstV‐1 genotypes, and the nonclassic MAstV‐6 (including Melbourne‐1 [MLB‐1] to MLB‐3), MAstV‐8 (HAstV Virginia2 [VA2], VA4, and human‐mink‐ovine‐like‐A [HMO‐A]) and MAstV‐9 (HAstV VA1, VA3, and HMO‐B) genotypes . Recently, HAstV‐MLB2 viral RNA was detected for the first time in the plasma of a child with severe AGE and high fever, suggesting the potential of the HAstV to spread beyond the gastrointestinal tract …”

Genome Sequences of 12 Mycobacteriophages Recovered from Archival Stocks in Japan

“…The International Committee on Taxonomy of Viruses (ICTV) classification allowed the taxonomic classification of the recovered phages using these data (10). Phages A6, BK1, GS4E, D29, C3, B1, and PP of cluster A were classified into the genus L5virus.…”

Virucides in apiculture: persistence of surrogate enterovirus under simulated field conditions

“…are members of order Picornavirales . They are Deformed Wing Virus (DWV), Sacbrood Virus (SBV), and Slow Bee Paralysis Virus (SBPV) (genus Iflavirus , family Iflaviridae ), Black Queen Cell Virus (BQCV) (g. Triatovirus , f. Dicistroviridae ) and acute paralysis complex viruses [Acute Bee Paralysis Virus (ABPV); Kashmir Bee Virus (KBV); Israel Acute Paralysis Virus (IAPV)] (g. Aparavirus , f. Dicistroviridae ) . Physicochemical properties of both f. Iflaviridae and f. Dicistroviridae have not been fully established .…”
