脉冲场凝胶电泳(Pu lsed F ield Gel E lectrophoresis,PFGE)技术是80年代初期发展起来的[1],该技术依靠有规律地改变电场的方向而使大分子DNA得以分离,电泳结果通常是条带图谱,通过观察电泳条带的差异分型。该方法的发展成熟为监测控制细菌的流行提供了广阔的前景,对于细菌性
Pulsed field gel electrophoresis (PFGE) was developed in the early 1980s [1]. This technique relies on the regular change of electric field to separate the macromolecular DNA. The electrophoresis result is usually Banding patterns were observed by observing the differences in electrophoretic bands. The maturity of this method provides a broad prospect for monitoring the prevalence of bacterial control,
