Distribution and epidemiologic trends of HBV genotypes and subtypes in 14 countries neighboring china.

ABSTRACT: BACKGROUND:The number of cases of HBV infection reported by the WHO for each district and country is positively correlated with the number of HBV sequences in the database isolated from the corresponding district and country. OBJECTIVES:This study determined distribution characteristics of HBV genotypes and subtypes in 14 countries neighboring China. The progress made in genomic research involving HBV was also reviewed. MATERIALS AND METHODS:Nine hundred fifty-one complete genome sequences of HBV from 14 countries neighboring China were selected from NCBI. The sequence-related information was analyzed and recorded. One hundred seventy-two sequences of HBV genotype B were screened for alignment using DNA star and MEGA 5.1. RESULTS:Dominant HBV genotypes in the countries neighboring China we
