constitute a family of small DNA viruses that infect a variety of hosts.
Merkel cell polyomavirus belongs to the Polyomaviridae
family of viruses, which is a group of nonenveloped, small, double-stranded DNA viruses.
Among oncogenic viruses are those in the Polyomaviridae
family, whose members infect an array of vertebrate species, including birds, humans, nonhuman primates, bovids, rodents, and sea lions (1,2).
Within the family of Polyomaviridae
are 4 known viruses directly associated with malignancy, namely, Polyomavirus hominis 1 (BK) virus, John Cunningham virus (JCV), KI polyomavirus, and mumps virus.
To the Editor: Human polyomaviruses (HPyVs) are members of the family Polyomaviridae
Both are double-stranded DNA viruses in the family Polyomaviridae
is a family of nonenveloped viruses with a circular double-stranded DNA genome.
Recently, 2 novel viruses of the family Polyomaviridae
were detected in respiratory samples and named KI (2) and WU polyomavirus (WUPyV) (3).
