Here we report, for the first time, the nearly full-length genome sequence of porcine bocavirus (PBoV), a recently discovered parvovirus from pigs. Phylogenetic trees based on this genome sequence showed that PBoV belongs to the branch containing the genus Bocavirus, which comprises canine minute virus (CnMV), bovine parvovirus, gorilla bocavirus and human bocavirus (HBoV), and was most closely related to the group containing CnMV. PBoV was predicted to contain three potential ORFs encoding the non-structural protein NS1, the characteristic NP1 protein and the capsid protein VP1/VP2, with an organization similar to that of known bocaviruses. Interestingly, the NS1 gene of PBoV was more similar in length to the homogeneous gene found in HBoV than to those of other known bocaviruses. In addition, highly conserved unique splice-donor and -acceptor sites were identified in the NS1 gene of HBoV and PBoV.
