摘要 目的对皮肤病原真菌分子的检测与建立进行分析和研究。方法根据GenBank序列数据库中集中医学重要真菌的核糖体RNA的编码基因中内转录间隔区的基因排列,设计一对通用引物,摸索最佳的反应条件,建立PCR—RFLP方法,将PCR—RFLP方法与传统的形态学方法的检测分离开来,并且将临床抽取的真菌标本和细菌培养标本180例,进行比对。结果所检验的实验菌,都出现预期大小的基因片段,对PCR的产物,需要使用两种限制性酶来消化PCR产物,然后在进行一一的鉴定。结果经过鉴定发现,鉴定结果与培养方法的结果高度是一致的。结论 PCR—RFLP的方法对真菌检测的速度比较快,并且灵敏度较高,是一种非常值得推广的方法。
