Trichomonasvirus

Trichomonasvirus is a genus of viruses, in the family Totiviridae. The protozoan parasite Trichomonas vaginalis serves as the natural host. There are currently four species in this genus, including the type species Trichomonas vaginalis virus 1.[1][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]

gollark: If you generate random numbers sampled out of the range from 1 to infinity then... 100% minus some infinitesimally small amount are too big to fit in the universe?
gollark: It's not a "99.99999999% chance". We're dealing with infinities here.
gollark: Okay, no, I can think of how you would do that, although not a uniform distribution across the entire range.
gollark: I'm not sure how you would even do that without taking infinite or at least arbitrarily large amounts of time.
gollark: So... *don't* generate random numbers between 0 and infinity?
