Eight babies all delivered by Caesarean section were observed for evidence of colonization by E. coli from birth until discharge from hospital 10 to 14 days later. Faecal specimens were cultured daily for E. coli as were swabs from the rectum, groin, umbilicus, head, hands und mouth. Different serotypes of E. coli were isolated from four babies on day 1, one baby on day 2, one baby on day 7 and two babies on day 9. Three babies excreted more than one serotype of E. coli. Serotypes of E. coli isolated from the faeces and rectum were usually isolated from the groin but less often from the umbilicus. Other sides were rarely colonized. In all instances except one the primary site of colonization appeared to be the gastrointestinal tract. Colonization by E. coli was influenced by antibiotic therapy and possibly by the method of feeding.
对8名均通过剖宫产分娩的婴儿进行了观察，从出生直至10至14天后出院，以寻找大肠杆菌定植的证据。每天对粪便标本以及来自直肠、腹股沟、脐部、头部、手部和口腔的拭子进行大肠杆菌培养。在第1天从4名婴儿中分离出不同血清型的大肠杆菌，第2天从1名婴儿中分离出，第7天从1名婴儿中分离出，第9天从2名婴儿中分离出。3名婴儿排出了不止一种血清型的大肠杆菌。从粪便和直肠分离出的大肠杆菌血清型通常也能从腹股沟分离出，但从脐部分离出的情况较少。其他部位很少被定植。除一例以外，在所有情况下，定植的主要部位似乎都是胃肠道。大肠杆菌的定植受抗生素治疗的影响，可能还受喂养方式的影响。
