采用近年来兴起的一种新的分子生物学分型技术RAPD 即AP- PCR 对20 株4 种不同双歧杆菌进行了基因指纹图谱的构建,其结果不同双歧杆菌种间存在同源性和多态性。本研究结果表明RAPD 技术可用于双歧杆菌菌种鉴定及分型
Using a new molecular biology typing technique RAPD, AP-PCR, which has arisen in recent years, the genetic fingerprinting of 20 strains of 4 different Bifidobacteria was carried out. The results showed that there were homologies among different Bifidobacteria and more State. The results of this study show that RAPD technology can be used to identify and type Bifidobacterium species
