Parvovirus coat protein homo60mer, Carnivore protoparvovirus 1.

Parvovirukset ovat parvoviridae-heimoon kuuluva virussuku. Parvovirukset ovat erittäin pienikokoisia, lineaarisia, segmentoitumattomia DNA-viruksia, genomaltaan keskimäärin 5 kbp. Parvovirukset ovat maailman pienimpiä luonnosta löytyviä viruksia (latinalainen nimi parvus tarkoittaa pientä), kooltaan 23–28 nm.

Yhdenkään parvovirusten perheen viruksen ei tunneta tarttuvan ihmiseen, mutta ihminen voi saada tartunnan kolmesta muusta parvovirusten perheen generasta. Ne ovat dependovirukset, erythrovirukset ja bocavirukset.

Parvovirinae perheen kahdeksasta tunnetusta muodosta viiden on todettu tarttuvan ihmiseen.

  • I) Bocaparvovirus (e.g. human bocavirus 1)
  • II) Dependoparvovirus (e.g. adeno-associated virus 2)
  • III) Erythroparvovirus(e.g. parvovirus B19)
  • IV) Protoparvovirus (e.g. bufavirus 1a)
  • V) Tetraparvovirus (e.g. human parv4 G1)

Parvoviruksia ovat muun muassa koiran parvovirus ja kissarutto.
