HBV core variants circulating in a Piaroa Amerindian with OBI. a Agarose gel electrophoresis of HBV core amplicons. BP21 repeated amplifications of isolate BP21 allow identifying several variants, each one more frequently found in one amplicon. BP21¹ variant carrying a deletion in the core region (309 nt). BP21² variant carrying a premature stop codon and a deletion. BP21³ wild type variant (393 nt). b Amino acid alignments of the core region amplified in several isolates. Numbers indicate the aa position. Stop codon (*) and deletion (...) are shown.
