最近研究表明〔１，２〕，世界各地分离的ＧＢＶＣ／ＨＧＶ株间存在不同的基因型，即１型、２型和３型。上述分型所采用的核酸序列大多数来自非洲、欧美和日本等地，我国ＧＢＶＣ／ＨＧＶ分离株的基因型及其分布则报道较少。为此，本研究应用分子进化学方法对从我国５城市 Recent studies have shown that [1,2], there are different genotypes of GBV C / HGV strains isolated around the world, namely type 1, type 2 and type 3. Most of the nucleic acid sequences used in the above typing come from Africa, Europe, the United States and Japan. However, the genotypes and distribution of GBV-C / HGV isolates in China are reported with few reports. To this end, this study applied molecular methods of chemistry to five cities from China
