Fecal colonization by extended-spectrum-beta-lactamase-producing Escherichia coli in 912 stool samples collected from 154 neutropenic patients with cancer, hospitalized at two teaching institutions, was prospectively studied. Forty-nine (31.8%) patients were colonized, 22 of them at hospital admission. Most strains were clonally unrelated and carried a CTX-M-9 group enzyme.
