Surface protein alignment of the two OBI positive samples with the reference sequence AF100309 from the HBVdb. The alignment shows aa 100 to 191 of the S gene. The MHR spans aa 99–169 and the "a" determinant span aa 124–147. The amplicon starts from aa 117. Sequences shown as a dot have the same aa as the reference sequence; only variations are shown. An asterisk indicates that the sequence was terminated by a transcribed stop codon.
