A total of 2525 strains of Escherichia coli were isolated from the faeces of 33 mothers, the faeces of their babies and the mucus extracted from the babies' mouths after delivery. Of these strains 1832 could be O-serotyped with 150 O antisera. E. coli were isolated from 28 babies and the same serotypes as were found in their mothers were found in 22 of them. E. coli was isolated from only 14 of the mucus specimens but in 12 of these at least one of the serotypes present was subsequently found in the babies' stools.
共从33位母亲的粪便、她们婴儿的粪便以及分娩后从婴儿口腔中提取的黏液中分离出2525株大肠杆菌。其中1832株可用150种O抗血清进行O血清分型。从28名婴儿中分离出了大肠杆菌,其中22名婴儿体内发现的大肠杆菌血清型与其母亲体内的相同。仅从14份黏液样本中分离出了大肠杆菌,但其中12份样本中,随后在婴儿粪便中发现了至少一种存在的血清型。
