Trichomonasvirus
Virus classification
Group:
Group III (dsRNA)
Family:
Totiviridae
Genus:
Trichomonasvirus
Type Species

Trichomonasvirus is a genus of viruses, in the family Totiviridae. Protozoan parasite trichomonas vaginalis serve as natural hosts. There are currently four species in this genus, including the type species Trichomonas vaginalis virus 1.[1][2]

Taxonomy

Group: dsRNA

Order: Unassigned

[2]

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.[1]

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.[1]
