Candidate passages:
Sudan virus was first introduced as a new "strain" of Ebola virus in 1977.
In 2000, it received the designation Sudan Ebola virus and in 2002 the name was changed to Sudan ebolavirus.
Previous abbreviations for the virus were EBOV-S (for Ebola virus Sudan) and most recently SEBOV (for Sudan Ebola virus or Sudan ebolavirus).
The virus received its final designation in 2010, when it was renamed Sudan virus (SUDV). 
Ebola virus was first introduced as a possible new "strain" of Marburg virus in 1977 by two different research teams.
At the same time, a third team introduced the name Ebola virus.
In 2000, the virus name was changed to Zaire Ebola virus, and in 2005 to Zaire ebolavirus.
However, most scientific articles continued to refer to Ebola virus or used the terms Ebola virus and Zaire ebolavirus in parallel.
Consequently, in 2010, the name Ebola virus was reinstated.
Previous abbreviations for the virus were EBOV-Z (for Ebola virus Zaire) and most recently ZEBOV (for Zaire Ebola virus or Zaire ebolavirus).
In 2010, EBOV was reinstated as the abbreviation for the virus. 
Reston virus is pronounced ‘rɛstən vɑɪrəs (IPA) or res-tuhn vahy-ruhs in English phonetic notation.
According to the rules for taxon naming established by the International Committee on Taxonomy of Viruses (ICTV), the name Reston virus is always to be capitalized, but is never italicized, and may be abbreviated (with RESTV being the official abbreviation).
Reston virus was first introduced as a new "strain" of Ebola virus in 1990.
In 2000, it received the designation Reston Ebola virus and in 2002 the name was changed to Reston ebolavirus.
Previous abbreviations for the virus were EBOV-R (for Ebola virus Reston) and most recently REBOV (for Reston Ebola virus or Reston ebolavirus).
The virus received its current designation in 2010, when it was renamed Reston virus (RESTV).
A virus of the species "Reston ebolavirus" is a Reston virus (RESTV) if it has the properties of Reston ebolaviruses and if its genome diverges from that of the prototype Reston virus, Reston virus variant Pennsylvania (RESTV/Pen), by ≤10% at the nucleotide level. 
Since it was first recorded, LdMNPV has been host to numerous common names, taxonomical names, and acronyms.
It was first reported in 1891, as 'Wipfelkrankheit'.
Wipfelkrankheit is German for "tree top disease".
"Tree top disease" is also used in English, another common term, 'wilt disease' has been in use for over a century.
The term 'flacherie', a name which refers to an entirely different disease was once identified as this virus.
Another antiquated term, "caterpillar cholera" was also used early in the 20th century.
The virus has also been referred to as "Borralinivirus reprimens".
It has many modern names, including 'Gypsy Moth Nucleopolyhedrosis Virus', Lymantria dispar MNPV, Lymantria dispar multinucleocapsid nuclear polyhedrosis virus, Lymantria dispar nuclear polyhedrosis virus, Lymantria dispar nucleopolyhedrovirus, and Lymantria disper nuclear polyhedrosis virus, with varying acronyms attached or unattached including LdMNPV, and LdNPV.
Currently, as by taxonomy, the viral species is known as Lymantria dispar multicapsid nuclear polyhedrosis virus. 
Taï Forest virus was first introduced as a new "strain" of Ebola virus in 1995.
In 2000, it received the designation Côte d'Ivoire Ebola virus, and in 2002 the name was changed to Côte d'Ivoire ebolavirus.
(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).
