Rapid detection of esbl-producing enterobacteriaceae in blood cultures

Abstract

We rapidly identifed extended-spectrum β-lactamase (ESBL) producers prospectively among 245 gram-negative bacilli-positive cultured blood specimens using the Rapid ESBL Nordmann/Dortet/Poirel test and direct bacterial iden tifcation using matrix-assisted laser desorption ionization time-of-fight mass spectrometry. This combination identi fed ESBL-producing Enterobacteriaceae within 30 min and had high predictive values.
