The HBoV2B cluster included 76 of the 101 bocavirus strains reported here ( Figure 1 ). Two nearly full HBoV2B genome sequences demonstrated a pair-wise amino acid divergence in VP1 of 0.45% (Table 2 ) (NI-213 and NI-327; GenBank accession numbers FJ973560 and FJ973559). Greater divergence was observed when these strains were compared with the VP1 of HBoV2A strains (average divergence, 3.9% [range, 3.3%-4.5%] ( Table 2 ). The nucleotide and amino acid distances at the other loci are shown in Table 2 .
