The O and H serotypes of Escherichia coli that were present along the entire length of the gastrointestinal tract of patients with small intestinal bacterial overgrowth were studied. Multiple sero- and biotypes were represented, although usually a single serotype predominated in each patient. In a number of cases the different O:H serotypes were antigenically related indicating that antigenic degradation was occurring. The serotypes isolated from the stomach and small intestine were represented in the faeces. In general, within the limitations of this study, there appears to be a stable ecosystem in each patient and it may require specific oral antibiotics to alter it.
对小肠细菌过度生长患者整个胃肠道中存在的大肠杆菌O和H血清型进行了研究。虽然通常每个患者中单一血清型占主导,但存在多种血清型和生物型。在一些病例中,不同的O:H血清型具有抗原相关性,表明抗原降解正在发生。从胃和小肠分离出的血清型也存在于粪便中。总体而言,在本研究的局限性范围内,每个患者体内似乎存在一个稳定的生态系统,可能需要特定的口服抗生素来改变它。
