Characteristics of groups of urine and faecal Escherichia coli clones from 11 women with symptomatic urinary tract infection according to colonization behaviour
Colonization group (I, II, or III) was defined based on the correspondence of urine and faecal clones in individual subjects. In group I, a single faecal clone was detected, corresponding with the urine clone (U=F). In group II, multiple faecal clones were detected, including the subject's urine clone plus ⩾1 distinct ‘faecal only’ clone(s). In group III, the clones detected in faeces were all ‘faecal only’, i.e. did not include the urine clone.
Group I (U=F) vs. groups II+III (urine): for absolute virulence score, P=0·06 (Mann–Whitney U test); for % with virulence score ⩾4, P>0·10 (Fisher's exact test); for % from phylogenetic group B2 or group D, P=0·05 (Fisher's exact test).
Group I (urine=faecal) vs. groups II+III (faecal only), P>0·10 (Fisher's exact test).
Groups II+III (urine) vs. groups II+III (faecal only); for absolute virulence score, P=0·016 (Mann–Whitney U test); for % with virulence score ⩾4, P=0·01 (Fisher's exact test); for % from phylogenetic group B2 or group D, P=0·04 (Fisher's exact test).
