Bacteremia Due to Extended-Spectrum -Lactamase-Producing Escherichia coli in the CTX-M Era: A New Clinical Challenge

Abstract

ESBL-producing E. coli is a significant cause of bloodstream infection in hospitalized and nonhospitalized patients in the context of the emergence of CTX-M enzymes. Empirical treatment of sepsis potentially caused by E. coli may need to be reconsidered in areas where such ESBL-producing isolates are present.
