| Abstract: | Objective To investigate epidemiological distribution of HBV genotypes and the relationship between sub- genotype and clinical situations of HBV infection.Methods Thirty - five HBV DNA - positive serum samples identified as genotype B by nested PCR with sequence analysis of S gene were chosen randomly,and their subgenotypes (Ba and Bj) were determinated by sequence analysis of preC/C gene,the results of sequence anatysis were compared to the sequence of Gene- bank.Results All the subgenotypes of thirty - five cases were HBV genotype Ba,and no subgenotype of Bj was found. Conclusion The predominant subgenotype of HBV in Jiangsu Changzhou is HBV genotype Ba. |
