Rapid detection of OXA-48-producing Enterobacteriaceae by matrix-assisted laser desorption ionization-time of flight mass spectrometry. J Clin Microbiol. 2016 Mar;54(3):754-9.1098-660X10.1128/JCM.02496-15https://hdl.handle.net/2183/48713Brief report[Abstract] A rapid and sensitive (100%) matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) assay was developed to detect OXA-48-type producers, using 161 previously characterized clinical isolates. Ertapenem was monitored to detect carbapenem resistance, and temocillin was included in the assay as a marker for OXA-48-producers. Structural analysis of temocillin is described. Data are obtained within 60 min.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Bacterial Typing TechniquesEnterobacteriaceaeSpectrometry, Mass, Matrix-Assisted Laser Desorption-Ionizationbeta-Lactamasesjournal articleopen access
