Taï Forest virus (TAFV) |
The species Taï Forest ebolavirus (/tɑːˈiː/)[1] is a virological taxon included in the genus Ebolavirus, family Filoviridae, order Mononegavirales. The species has a single virus member, Taï Forest virus (TAFV).[1] The members of the species are called Taï Forest ebolaviruses.[1]
Tai Forest ebolavirus has been seen in a single human infection due to contact with chimpanzees from the
Nomenclature
The name Taï Forest ebolavirus is derived from
The species was introduced in 1998 as Cote d'Ivoire Ebola virus.[3][4] In 2002, the name was changed to Cote d'Ivoire ebolavirus.[5][6] The name was proposed to be changed to Taï Forest ebolavirus in 2010,[1] and this proposal was immediately accepted by the ICTV.[citation needed]
A virus of the genus Ebolavirus is a member of the species Taï Forest ebolavirus if:[1]
- it is endemic in Côte d'Ivoire
- it has a genome with three gene overlaps (VP35/VP40, GP/VP30, VP24/L)
- it has a genomic sequence different from Ebola virusby ≥30% but different from that of Taï Forest virus by <30%.
Taï Forest virus (
Use of term
Taï Forest virus (abbreviated TAFV) was first described in 1995 as a new "strain" of
Previous designations
Taï Forest virus was first introduced as a new "strain" of Ebola virus in 1995.[7] In 2000, it received the designation Côte d'Ivoire Ebola virus,[9][10] and in 2002 the name was changed to Côte d'Ivoire ebolavirus.[5][6] (both times misspelling "Côte"). Other names circulating in the literature were the correct Côte d'Ivoire Ebola virus and Côte d'Ivoire ebolavirus, and the jargon terms Ivory Coast Ebola virus and Ivory Coast ebolavirus. Previous abbreviations for the virus were EBOV-CI (for Ebola virus Côte d'Ivoire or Ebola virus Côte d'Ivoire), EBOV-IC (for Ebola virus Ivory Coast), ICEBOV (for Ivory Coast Ebola virus or Ivory Coast ebolavirus) and most recently CIEBOV (for Cote d;Ivoire Ebola virus, Côte d'Ivoire Ebola virus, Côte d'Ivoire ebolavirus or Côte d'Ivoire ebolavirus). The virus received its final designation in 2010, when it was renamed Taï Forest virus (TAFV).[1]
Virus inclusion criteria
A virus of the species Taï Forest ebolavirus is a Taï Forest virus (TAFV) if it has the properties of Taï Forest ebolaviruses and if its genome diverges from that of the prototype Taï Forest virus, Taï Forest virus variant Côte d'Ivoire (TAFV/CI), by ≤10% at the nucleotide level.[1]
Disease
TAFV is one of four ebolaviruses that causes

Ecology
The ecology of TAFV is currently unclear and no reservoir host has yet been identified. Therefore, it remains unclear how TAFV was introduced into the western chimpanzee population.
Molecular biology
TAFV is basically uncharacterized on a molecular level. However, its genomic sequence, and with it the genomic organization and the conservation of individual open reading frames, is similar to that of the other four known ebolaviruses. It is therefore currently assumed that the knowledge obtained for EBOV can be extrapolated to TAFV and that all TAFV proteins behave analogous to those of EBOV.[citation needed]
