Distribution of the sequence types of the E. coli commensal and BSI collections isolates.

The number of isolates and the percentage are presented in the table. We compared the ST diversity of E. coli isolates from BSI (all portals of entry, urinary portal of entry and digestive portal of entry) with a collection of commensal isolates, for all STs present in at least 5 strains in at least one of the two collections. We show the odds ratio (with 95% CI) for the risk of infection associated with colonization by each ST (logistic model of infection status as a function of the ST). STs with odds ratio significantly different from 1 are highlighted in bold. (XLSX)
