Full genome mapping image with a standard strain D00329, genotype B1.

<p>Full HBV genome mapping of obtained twenty-one isolates and known HBV genomes of genotype B and C. Besides the isolate name, age, sex, and nucleotide length are described. At the core region, all genotype B4 isolates have different pattern from genotype B1 or B6 (square in broken line), and almost the same pattern as genotype B2, B3, B5, B7, and C, suggesting they were recombinant at core region strains. Pre-S deletions as shaded squares were recognized in five isolates.
