Genus: Tapwovirus

Genus: Tapwovirus

Distinguishing features

Species are placed in the genus based upon phylogeny and host range.



Not reported.

Nucleic acid

Bisegmented, negative-sense RNA.


Wēnzhōu tapeworm virus 1 (WzTWV-1) genome encodes 5 proteins including a putative glycoprotein and four hypothetical proteins on RNA 2 and an RNA-directed RNA polymerase on RNA 1, identified on the basis of sequence similarity and structural properties shared with mononegavirus homologues (Shi et al., 2016).

Genome organization and replication

WzTWV-1 has two negative-sense RNA genome segments with reported sequence data of 6 kb (Shi et al., 2016).


Not reported.


Tapwovirus genome sequence was isolated from tapeworms.
