Trichomonasvirus


Trichomonasvirus is a genus of viruses, in the family Pseudototiviridae. The protozoan parasite Trichomonas vaginalis serves as the natural host. There are five species in this genus.

Taxonomy

The following four species are assigned to the genus:Trichomonasvirus vagiprimusTrichomonasvirus vagiquartusTrichomonasvirus vagiquintusTrichomonasvirus vagisecundus

Structure

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.

Life cycle

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.
