Keyword:  HIV-1基因亚型流行特征;
Abstract: 目的:研究贵州省HIV-1亚型变化与艾滋病流行特征的关系.方法:分3个时段检测贵州省多个地区190份HIV样本,用套式PCR扩增其env基因片段并测序分析,将实验结果与贵州省艾滋病流行特征进行相关分析.结果:1998年检出B、C/CRF07_BC/CRF08_BC和CRF01_AE 3种HIV-1毒株,此间艾滋病流行以B和C/CRF07_BC/CRF08_BC毒株为主,主要经血液途径传播(占86.4%);2002年检出毒株均为C/CRF07_BC/CRF08_BC亚型毒株,这一时段艾滋病流行以吸毒传播为主(占100%);2007年检出B、CRF01_AE、C/CRF07_BC/CRF08_BC等3种亚型毒株,以CRF01_AE毒株为主(占52.1%),主要经性传播.结论:贵州HIV流行毒株随时间和传播途径变化而发生变化;目前主要流行毒株为CRF01_AE亚型毒株,主要在性接触人群中传播;对HIV-1基因亚型进行及时监测,能够预测艾滋病的流行特征.
