红色毛癣菌种内分型

Strain typing in Trichophyton rubrum

  • 摘要: 目的: 建立一种快速、简单可重复的红色毛癣菌种内分型方法。方法: PCR扩增红色毛癣菌核糖体的非转录间隔区(NTS)的两个串联重复亚单位TRS-1和TRS-2区,进行种内分型。结果: 利用特殊的引物扩增63株红色毛癣菌TRS-1和TRS-2区,共产生8种特征性带型。结论: 这种PCR方法产生的特征性的指纹图提供了一种快速、稳定、简便的分子生物学种内分型方法,可应用于红色毛癣菌感染的流行病学研究

     

    Abstract: Objective: To develop a rapid and reproducible method in strain identification for Trichophyton rubrum. Methods: Two novel tandem repeat subelements(TRSs),TRS-1 and TRS-2,located in the Trichophyton rubrum rDNA nontranscribed spacer(NTS) were amplified from 63 strains of Trichophyton rubrum. Results: Specific amplification of TRS-1(6 type) and TRS-2(2 type) produced strain-characteristic bandinding patterns. Conclusions: This new method of typing Trichophyton rubrum will provide a rapid, stable molecular method about pathogenesis and epidemiology of this fungus.
