Trichomonasvirus is a genus of viruses, in the family Totiviridae. The protozoan parasite Trichomonas vaginalis serves as the natural host. There are four species in this genus.[1] [2]
The following four species are assigned to the genus:
Viruses in Trichomonasvirus are non-enveloped, with icosahedral geometries, and T=2 symmetry. The diameter is around 36 nm. Genomes are linear and non-segmented, around 4.6-4.9kb in length. The genome has 2 open reading frames.[1]

Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Protozoan parasite trichomonas vaginalis serve as the natural host.[1]
