【摘要】 目的了解丙型肝炎病毒（ＨＣＶ）和人类免疫缺陷病毒Ｉ型（ＨＩＶ－１）混合感染标本中ＨＣＶ基因型情况。方法采用了根据ＨＣＶ５′端非转译区基因组所设计的反相探针杂交测定方法（ＩＮＮＯＬｉＰＡ，ＨＣＶⅡ），对来自六个地区的１７份抗－ＨＣＶ和抗－ＨＩＶ－１双阳性标本进行ＨＣＶ基因型分型研究。结果在１７份标本中，７份（４１．１８％）为Ｉ（１ｂ）型病毒，５份（２９．４１％）为Ⅱ（２ａ／２ｃ）型病毒，５份（２９．４１％）为Ｉ型（１ｂ）和Ⅱ（２ａ／２ｃ）混合型病毒。结论发现ＨＣＶ与ＨＩＶ－１合并感染标本中存在Ｉ（１ｂ）型、Ⅱ（２ａ／２ｃ）型以及Ｉ（１ｂ）型与Ⅱ（２ａ／２ｃ）型混合型ＨＣＶ。值得注意的是对α－干扰素治疗不敏感并且较易趋于导致严重的慢性肝炎、肝硬化和肝细胞癌的Ⅱ型ＨＣＶ感染的比率占７０．５８％（１２／１７）。更多还原

【Abstract】 Objective To investigate the genotypes of HCV in the HCV and HIV 1 co infected samples.Methods Genotypes of HCV were determined by the INNO LiPA HCVII kit based on a reverse hybridization technique which was used for genotyping HCV and determining the variation in the 5′ untranslated regions of different HCVs.Seventeen of HCV and HIV 1 co infected samples derived from 6 different high risk geographic areas in China were studied.Results The results indicated that 7/17(41.18%) of samples were found to be of (1b) genotype,5/17(29.41%) were Ⅲ(2a/2c) genotype and 5/17(29.41%) were mixed genotype with Ⅱ (1b) and Ⅲ (2a/2c).Conclusion更多还原
