The species Marburg marburgvirus is the taxonomic home of two related viruses that form filamentous virions, Marburg virus (MARV) and Ravn virus (RAVV). Both viruses cause Marburg virus disease in humans and nonhuman primates, a form of viral hemorrhagic fever,[1] and both are Select Agents,[2] World Health Organization Risk Group 4 Pathogens (requiring Biosafety Level 4-equivalent containment),[3] National Institutes of Health/National Institute of Allergy and Infectious Diseases Category A Priority Pathogens,[4] Centers for Disease Control and Prevention Category A Bioterrorism Agents,[5] and are listed as a Biological Agents for Export Control by the Australia Group.[6]

Use of term

Marburg 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).[7] The members of the species (i.e. the actual physical entities) are called Marburg marburgviruses.[7] 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).[7]

Note

Marburg marburgvirus is pronounced ‘mɑrbərg ˌmɑrbərg’vɑɪrəs (IPA) or mahr-berg mahr-berg-vahy-ruhs in English phonetic notation.[7] According to the rules for taxon naming established by the International Committee on Taxonomy of Viruses (ICTV), the name Marburg marburgvirus is always to be capitalized, italicized, never abbreviated, and to be preceded by the word "species". The names of its members (Marburg marburgviruses) are to be capitalized, are not italicized, and used without articles.[7]

Previous designations

The species was introduced in 1998 as Marburg virus.[8][9] Because of easy confusion with its virus member Marburg virus, the species name was changed to Lake Viktoria marburgvirus in 2005.[10][11] In 2010, it was proposed to change the name to Marburg marburgvirus,[7] and this proposal was accepted in early 2012 by the ICTV.

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 <30% at the nucleotide level.[7]
