The virus genus Tetraparvovirus within the family Parvoviridae , subfamily Parvovirinae , currently comprises six closely related virus species in cloven-hoofed animals , primates (humans) and bats . No specific infectious disease is currently assigned to any member of the genus tetraparvovirus ; they are considered non-pathogenic (non-pathogenic) viruses. Their isolation was based on the identification of new DNA sequences in the blood, bone marrow, lymph nodes, liver and spleen of various host animals . The first species to be found in San Francisco in 2005 was a parvovirus-like virus in people who were at risk of sexual or parenteral infection and who had a negative HIV test . The virus was not found to be the cause of the acute viral disease. Antibodies against this human parvovirus 4 as well as viral RNA were found in other groups of patients with a high parenteral risk of infection (IV drug users , IVDU , haemophiles , patients with hepatitis C and hepatitis B virus ).
After the first isolation in humans, the University of Hong Kong succeeded in detecting similar viruses in even- toed ungulates ( domestic pigs , cattle , sheep , and later also yaks from northern China ). This virus group was originally as Hokoviren (of Ho ng ko ng University) or in part as Partetravirus called, the name Hokovirus but now stands for one in Klosterneuburg near Vienna, together with the closely related Klosneuvirus found giant virus from the family of mimiviridae . The name partetra- or tetraparvovirus results from the fact that the first animal isolates were genetically most similar to human parvovirus 4 (from the Greek τετρα- for four).
With regard to the virus morphology as well as the structure of the virus genome, the members of this genus do not differ from the other members of the subfamily Parvovirinae .
