"[A high prevalence of mixed viral populations (wild-type genomes and mutated sequences with a TAG stop codon in the distal preC region at position 1895-1897) was shown in the HBeAg-positive group; a homogeneous (either mutated or wild-type) viral population was detected in all but one of the long-term HBeAg-negative, untreated chronic carriers, thus suggesting that pre-core mutants can be rapidly generated and selected during the natural course of HBV infection.].
