Marburgvirus

Use of term

The genus Marburgvirus is a virological taxon included in the family Filoviridae, order Mononegavirales. The genus currently includes a single virus species, Marburg marburgvirus.

Previous designations

Until 1998, the family Filoviridae contained only one genus, Filovirus. Once it became clear that marburgviruses and ebolaviruses are fundamentally different, this genus was abolished and a genus "Marburg-like viruses" was established for marburgviruses. In 2002, the genus name was changed to Marburgvirus, and in 2010 and 2011 the genus was emended.

Genus inclusion criteria

A virus that fulfills the criteria for being a member of the family Filoviridae is a member of the genus Marburgvirus if

• its genome has one gene overlap
• its fourth gene (GP) encodes only one protein (GP1,2) and cotranscriptional editing is not necessary for its expression
• peak infectivity of its virions is association with particles ≈665 nm in length
• its genome differs from that of Marburg virus by
• its virions show almost no antigenic cross reactivity with ebolavirions

Genus organization

''Marburg marburgvirus''

The species was introduced in 1998 as Marburg virus.

Because of easy confusion with its virus member Marburg virus, the species name was changed to Lake Viktoria marburgvirus in 2005.

In 2010, it was proposed to change the name to Marburg marburgvirus, and this proposal was accepted in early 2012 by the ICTV.

Marburg marburgvirus (also referred to as Lake Victoria marburgvirus) is a virological taxon (i.e. a man-made concept) included in the genus Marburgvirus, family Filoviridae, order Mononegavirales. The species has two virus members, Marburg virus (MARV) and Ravn virus (RAVV). The members of the species (i.e. the actual physical entities) are called Marburg marburgviruses. The name Marburg marburgvirus is derived from the city of Marburg in Hesse, West Germany (where Marburg virus was first discovered), and the taxonomic suffix marburgvirus (which denotes a marburgvirus species).

Species inclusion criteria

A virus that fulfills the criteria for being a member of the genus Marburgvirus is a member of the species Marburg marburgvirus if it has the properties of marburgviruses (because there is currently only marburgvirus species) and if its genome differs from that of Marburg virus (variant Musoke) by
