Abstract:
OBJECTIVETo understand HBV serotypes and genotypes epidemiology in a northern city and a southern city in China.
METHODSUsing polymerase chain reaction (PCR) and direct sequencing of HBV DNA PCR products, the serotypes and genotypes of HBV in 530 from HBsAg positive samples. The enrolled patients were from Harbin, a northern city and Lianjiang, a southern city in China.
RESULTSComparison of the serotypes and genotypes of HBV between Harbin and Lianjiang showed that adrq+ was the most predominant hepatitis B virus serotype in both Harbin and Lianjiang (87.2% and 73.5%,respectively), adw2 was the next (12.0% and 25.7%, respectively); genotype C was the most frequent in Harbin and Lianjiang (87.8% and 73.2%, respectively), and genotype B was the next (12.2% and 26.1%, respectively) only 1 patient was infected by genotype D, and 1 patient was found to be co-infected by genotype B and C in Lianjiang.
CONCLUSIONThe results suggest that the percentage of HBV serotypes and genotypes between Harbin and Lianjiang was significantly different (P less than 0.001), but the main HBV serotype and genotype of the two cities were similar.
