Genus
dsDNA Viruses

Genus: Betapolyomavirus

Family: Polyomaviridae

Genus: Betapolyomavirus

 

Distinguishing features

The best-studied human polyomaviruses, BK polyomavirus (BKPyV) and JC polyomavirus (JCPyV) belong to this genus and are associated with nephropathy and progressive multifocal leukoencephalopathy, respectively. 

Virion

See discussion under family description.

Genus: Alphapolyomavirus

Family: Polyomaviridae

Genus: Alphapolyomavirus

 

Distinguishing features

Members infect humans and other mammals. Merkel cell polyomavirus (MCPyV) and raccoon polyomavirus RacPyV) are so far the only members known to cause cancer in their natural host.

Genus: Decapodiridovirus

 

Distinguishing features

Decapodiridoviruses are large (158 nm) icosahedral viruses that infect penaeid shrimp and crayfish. 

Virion

Other than diameter (158 nm) and icosahedral symmetry, little is known about members of this family.
