Diversity of E. coli in enteric microbiota from patients with E. coli bacteraemia compared with other patient groups. Frequency of different numbers of RAPD patterns among E. coli bacteraemia patients (n = 74), patients with other Gram negative bacteraemia (n = 42), and non-antibiotic exposed inpatient controls who had no infection and were not taking antibiotics (n = 70). Although a difference was detected between the two main groups (E. coli bacteraemia and non-antibiotic inpatient controls, p = 0.029), there were no overall differences between the three groups (p = 0.06)
