Parvoviruses are small single-stranded linear DNA viruses with a genome of approximately 5000 nucleotides, which have been found in a number of species such as human, swine, cattle and gorilla [8] . In swine, porcine parvovirus (PPV) is a known agent that causes reproductive failure [9] . However, in recent years a number of new parvovirusesporcine hokovirus (PHoV) [10] , porcine bocavirus (PBoV) [11] and porcine parvovirus 4 (PPV4) [12] -have been discovered in pigs, with their potential involvement in disease currently unknown.
