The Molluscum contagiosum virus or MCV is a species of virus in the poxvirus family, which causes the disease Molluscum contagiosum in humans. Virions have a complex structure and is consistent with the structure of the poxvirus family: an envelope, surface membrane, core, and lateral bodies. Virus may be contained within inclusion bodies and mature by budding through the membrane of the host cell giving rise to a large amount of viral shedding in a short period of time. Approximate measurements of the virus are 200 nm in diameter, 320 nm in length and 100 nm in height.[1]
There are 4 types of MCV, MCV-1 to -4. MCV-1 is the most prevalent in human infections,[2] and MCV-2 seen usually in adults and often sexually transmitted.[3][4] Polymerase chain reaction techniques are being developed to help confirm lesions as being caused by MCV,[5] and distinguish between strains.[6][7]
[edit] Genome
The genome is a non-segmented single molecule of linear, double-stranded DNA of 180000–200000 nucleotides. It is covalently linked at both ends and contain redundant, repeating sequences at both ends. 160 pudative genes have been identified.[8]
