Emergence and Dissemination of Extended‐Spectrum β‐Lactamase–Producing<i>Escherichia coli</i>in the Community: Lessons from the Study of a Remote and Controlled Population

Abstract

In this population, the frequency of ESBL increased with time because of the appearance of CTX-M ESBL, mimicking what occurs in the developed world. This resulted from the probable repeated introduction of new strains and plasmids and from interindividual dissemination. During the same period, antibiotic use substantially increased.
