The first human bocavirus (HBoV) was found in the nasopharyngeal secretion of a child with respiratory problems using a methodology closely related to that used here [8] . HBoV has been associated with lower respiratory tract symptoms and possibly diarrhea [5, [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] , and shows a very low degree of genetic variability worldwide [6, 23, 24] . HBoV2 was first reported in the stool of Pakistani children with non-polio acute flaccid paralysis (AFP) [10] , and then in Australian children and Chinese children with diarrhea [9, 25] . HBoV3 was first reported in the stool of Australian children with diarrhea [9] and then in stool from Nigerian, Tunisian, Nepalese and US children [5] . HBoV4 was reported in the stool of children with AFP from Nigeria and Tunisia [5] . HBoV 1/2/3 were also detected in untreated sewage water from throughout the US [26] . Recently, a novel bocavirus was identified in the feces of captive gorillas with diarrhea [6] and from wild gorillas and chimpanzees [7] . In 2009, a porcine bocalike virus (PBo-likeV) was reported in swine feces with postweaning multisystemic wasting syndrome in Sweden and 1854 bp of its partial genome sequenced [27] . In 2010, the nearly complete genomes of distinct porcine bocaviruses provisionally named PBoV1 and PBoV2 were characterized from feces of swine in China [28] . Finally, partial genome sequences of 2.4 Kb from another clade of porcine bocaviruses labeled 6V and 7V where also identified yielding three major bocavirus groups in swine (PBo-likeV, PBoV1/PBoV2, and 6V/7V).
