The homogeneity of fecal coliform flora in 52 schoolgirls was studied by serotyping and biotyping 10 randomly selected colonies in one fecal culture from each child. Ninety-eight clones were identified and of these 52 were dominant and 46 were minor strains. The probability of including at least one isolate of the dominant clone in a small random sample of colonies was calculated to be 86% for one colony, 94% for 2, 97% for 3, 99% for 4, and 99.3% for 5 randomly selected colonies.
通过对每个孩子粪便培养物中随机选取的10个菌落进行血清分型和生物分型，研究了52名女学生粪便大肠菌群的同质性。共鉴定出98个克隆，其中52个为优势菌株，46个为次要菌株。计算得出，在随机选取的少量菌落样本中，至少包含一个优势克隆分离株的概率为：选取1个菌落时为86%，2个菌落时为94%，3个菌落时为97%，4个菌落时为99%，5个菌落时为99.3%。
