摘要 目的探讨临床分离的耐氟康唑热带假丝酵母菌的ERG11基因突变情况及其与氟康唑耐药的关系。方法收集临床分离的热带假丝酵母菌,用ATB Fungus 3酵母菌药敏试剂盒测定其对氟康唑的敏感性。对8株耐氟康唑的菌株及随机选取的17株敏感株,提取基因组DNA,扩增ERG11基因并测序,测序结果与Gen Bank中的已知标准序列(M23673)进行比对分析。结果 25株热带假丝酵母菌均扩增到ERG11基因并成功测序,发现7个不同的碱基突变位点。耐药株错义突变位点为Y132F、S154F和K143Q,其中K143Q为首次报道;敏感株无错义突变位点。结论耐氟康唑的热带假丝酵母菌ERG11基因存在多个错义突变位点,且多为多位点突变,可能与其耐药性的产生有关。
