Bacteremia caused by Enterobacter asburiae misidentified biochemically as Cronobacter sakazakii and accurately identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry: a case report.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry may reduce misidentification of bacteria as C. sakazakii and improve the reporting rate of E. asburiae. This technique should be considered when biochemical bacterial misidentification is suspected.
