Community carriage of ESBL-producing<i>Escherichia coli</i>is associated with strains of low pathogenicity: a Swedish nationwide study

Abstract

E. coli host factors previously associated with higher pathogenicity were all more common in BSIs compared with carriers. This indicates that the risk of invasive infection with EPE may be relatively modest in many community carriers and that EPE carriage of high-risk strains should be the focus of attention for prevention.
