Specimens of faeces were obtained at weekly intervals for one year from patients in a female medical ward and Escherichia coli present were typed. The faecal E. coli population of the patients was constantly changing. No serotypes of E. coli were dominant, but on 31 occasions during the year small clusters of patients carried the same type.
在一年的时间里,每周从一个女性内科病房的患者那里获取粪便样本,并对其中存在的大肠杆菌进行分型。患者粪便中的大肠杆菌菌群一直在变化。没有哪种大肠杆菌血清型占主导地位,但在这一年中有31次,一小群患者携带相同类型的大肠杆菌。
