Intra-species analysis of pulsed field gel electrophoresis (PFGE) on human fecal Bifidobacterium longum isolates revealed that a majority of 12 Japanese subjects harbored strains of unique PFGE types or subtypes over a 68-week period, suggesting that "indigenous"Bifidobacterium strains remain stable for a considerable time in each individual intestinal microbiota.
对人类粪便中分离出的长双歧杆菌进行脉冲场凝胶电泳（PFGE）种内分析发现，在68周的时间里，12名日本受试者中的大多数都携带独特PFGE类型或亚型的菌株，这表明“本土”双歧杆菌菌株在每个个体的肠道微生物群中相当长一段时间内保持稳定。
