Previous work showed that on the basis of O serotyping alone of Escherichia coli, the majority of babies acquired the same O serotype as was found in the stools of their respective mothers. Further characterization of the E. coli by H serotyping, determination of their antibiotic resistance and ability to ferment six carbohydrates showed that in the majority of cases the previous results were confirmed. In a minority of cases this further testing showed that the strains were not identical. In some instances a number of strains isolated from the same pair showed different combinations of the markers used.
先前的研究表明，仅基于大肠杆菌的O血清型分类，大多数婴儿获得的O血清型与在其各自母亲粪便中发现的相同。通过H血清型对大肠杆菌进行进一步鉴定、测定其抗生素耐药性以及发酵六种碳水化合物的能力，结果表明在大多数情况下，先前的结果得到了证实。在少数情况下，进一步检测表明这些菌株并不相同。在某些情况下，从同一对母婴中分离出的一些菌株显示出所用标记的不同组合。
