Notes on Genus: Tibrovirus

enveloped bacilliform
enveloped bacilliform

Type member: Tibrogargan virus


General Description

This is one of the animal virus genera in the family Rhabdoviridae. The genus is characterised by its bacilliform, enveloped, particles which contain a monopartite ssRNA genome that is more than 12kb in size and which has a distinctive arrangement of ORFs. The name is taken from the type member.


Virions are bullet- or cone-shaped, about 140-200 nm long and 60-80 nm in diameter.


Monopartite, linear, single-stranded, negative sense RNA, about 13300 nucleotides long.

Genus Genomic Organization

There are the five structural proteins common to all members of the family and three additional genes encoding proteins of unknown function, arranged as N-P-M-U1-U2-G-U3-L.
