Abstract：Objective To understand the distribution of hepatitis B virus (HBV) genotypes in Zhuhai area and to analyze the relationship between HBV genotypes and patients with hepatitis B. Methods A polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis assay amplifying S-segment sequences of HBV-DNA were used for analyzing the distribution of HBV genotypes among 62 HBV carriers (ASC group),63 patients with chronic hepatitis B (CHB group),7 patients with severe chronic hepatitis B (CSH group)and 5 cases liver cirrhosis (LC group). Results The proportion of HBV genotyjpes B and C was 52.6% and 47.4%. There were no significant differences of indexes related to liver function damage (ALT) or serum HBV DNA levels between subtype B and subtype C infected patients. Conclusion The genotypes B and C are two predominant genotypes in Zhuhai area;genotype C may be associated with the development of hepatitis.
