Abstract
The HBV HBsAg coding region of a hepatitis B patient was analyzed by PCR amplification, bacteriophage cloning and nucleotide sequencing. It was showed that among different clones from the same patient there were point mutations and these different nucleotide changes were not resulted from the methodologies. It is concluded that there are polymorphic HBV genomes within the same hepatitis B patient
