The faeces of nine subjects eating mainly at home were collected at regular intervals over periods ranging from 2--5 months. Although a large number of serotypes of E. coli were isolated, the variety per subject was lower than is usually found. In most subjects only a limited number of serotypes persisted over most of the periods of study while many serotypes were only isolated on single occasions.
对九名主要在家用餐的受试者的粪便进行了为期2至5个月的定期收集。虽然分离出了大量大肠杆菌血清型,但每个受试者的种类比通常发现的要少。在大多数受试者中,在研究的大部分时间段内只有有限数量的血清型持续存在,而许多血清型仅在单次检测中被分离出来。
