Discovery
TTMDV, which stands for transfusion transmitted midi virus or torque teno midi virus was first isolated in 2005 from patients with an acute viral infection syndrome.
Because of the circular nature of its DNA
genome, TTMDV (which was provisionally named small anellovirus 1) was classified as an anellovirus. Genomic analysis confirmed this classification.
Like other anelloviruses, TTMDV is quite common, even in healthy individuals. It has been found in various bodily fluids, including saliva and
nasopharyngeal aspirates.
Genome and capsid
Like other members of its family, TTMDV's
genome is a circular single-stranded piece of
DNA of a negative polarity. The genome is approximately 3.2 kb in length, which is slightly smaller than that of
TTV and slightly larger than that of
TTMV. It is a non-
enveloped virus with a
capsid about 40 nm in diameter. The capsid possesses T=1 icosahedral symmetry.
Clinical
The pathogenic effects of TTMDV in humans is not known. However, it has been isolated from diarrhea cases.
