| identification of novel porcine and bovine parvoviruses closely related to human parvovirus 4. | human parvovirus 4 (parv4), a recently discovered parvovirus found exclusively in human plasma and liver tissue, was considered phylogenetically distinct from other parvoviruses. here, we report the discovery of two novel parvoviruses closely related to parv4, porcine hokovirus (phov) and bovine hokovirus (bhov), from porcine and bovine samples in hong kong. their nearly full-length sequences were also analysed. parv4-like viruses were detected by pcr among 44.4 % (148/333) of porcine samples (i ... | 2008 | 18632954 |
