HBoV1 has been classified as a new member of the genus Bocavirus of the family Parvoviridae [25] , of which bovine parvovirus (BPV1) and minute virus of canines (MVC) are the prototypes [26, 27] . In comparison with the BPV1 and MVC genomes, the HBoV1 genome sequences obtained previously appeared to exclude the two termini, and therefore, were incomplete [28] . However, sequencing of the head-to-tail junctions of HBoV1 and HBoV3 ''episomes,'' which had been amplified in DNA samples extracted from HBoV1-infected differentiated human epithelial cells and from intestinal biopsies of HBoV3-infected patients, respectively, revealed portions of the HBoV termini [29, 30] . Notably, these sequences were conserved with the terminal sequences of BPV1 and MVC [28] .
