OBJECTIVES There are regions in the core gene of hepatitis B virus (HBV) where missense mutations are clustered, and mutations in that region are related to severe liver disease. However, there were some differences of the major regions for mutation clustering among ethnic groups. To explore the phenomenon of clustering mutations in Korean patients with chronic HBV infection and to elucidate th...
AIMS The aims of this study were to develop bioinformatics tools to explore ultra-deep pyrosequencing (UDPS) data, to test these tools, and to use them to determine the optimum error threshold, and to compare results from UDPS and cloning based sequencing (CBS). METHODS Four serum samples, infected with either genotype D or E, from HBeAg-positive and HBeAg-negative patients were randomly sele...
Lamivudine has been shown to be effective in patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B, but its long-term efficacy and the rate of resistant mutations in patients with HBeAg-negative chronic hepatitis B is less clear. Twenty-nine patients with HBeAg-negative chronic hepatitis B, who have received lamivudine for at least 1 year were studied to determine the antivir...
Eight hepatitis B virus (HBV) isolates of genotype G were recovered from patients and sequenced over the entire genome. Six of them had a genomic length of 3,248 bp and two had genomic lengths of 3,239 bp (USG15) and 3,113 bp (USG18) due to deletions. The 10 HBV/G isolates, including the 8 sequenced isolates as well as the original isolate (AF160501) and another isolate (B1-89), had a close seq...
