Nyamiviridae: Proposal for a new family in the order Mononegavirales


Nyamanini virus (NYMV) and Midway virus (MIDWV) are unclassified tick-borne agents that infect land birds and seabirds, respectively. The recent molecular characterization of both viruses confirmed their already known close serological relationship and revealed them to be nonsegmented, single- and negative-stranded RNA viruses that are clearly related to, but quite distinct from, members of the order Mononegavirales (bornaviruses, filoviruses, paramyxoviruses, and rhabdoviruses). A third agent, soybean cyst nematode virus 1 (SbCNV-1, previously named soybean cyst nematode nyavirus), was recently found to be an additional member of this new virus group. Here, we review the current knowledge about all three viruses and propose classifying them as members of a new mononegaviral family, Nyamiviridae.

Jens H. Kuhn, Ralf G. Dietzgen, Norbert Nowotny, and Lin-Fa Wang are the members of the International Committee on Taxonomy of Viruses (ICTV) Mononegavirales Study Group, and are the chairs of the ICTV Filoviridae, Rhabdoviridae, Bornaviridae, and Paramyxoviridae Study Groups, respectively.


The taxonomic changes suggested here have not been endorsed by the International Committee on Taxonomy of Viruses (ICTV) Executive Committee, may differ from any new taxonomy that is ultimately approved by the ICTV, and is presented for discussion only but has no official standing at the time of publication.
