摘要 目的:探索广西地区丙型肝炎病毒(HCV)基因型的分布特征。方法:收集广西地区137例HCV-RNA阳性患者的血清样本,采用逆转录巢式PCR法扩增HCV NS5B区段,对PCR终产物纯化测序,测序结果与Genbank中的标准株全基因序列比对,并构建HCV NS5B区段系统进化树。结果:广西地区137例样本中,主要基因型为1b型(58.4%),其次是6a型(12.4%),3b型(10.2%),1a型(7.3%),2a型(7.3%),3a型(4.4%)。进一步分析表明,HCV基因型分布与性别无关(P>0.05),而与年龄有关(P<0.05),3型及6a型主要见于年轻患者。结论:构建HCV NS5B区段系统进化树能得到准确的HCV基因型;广西地区HCV基因型呈多样化,以1b型为主,6a型和3b型次之,且新发现6例3a型;基因分型为不同基因型的HCV感染者的治疗和疗效预测提供了理论依据。
