Abstract
A new protocol for Enterobacteriaceae identification and detection of carbapenemase-producing isolates from blood cultures by combining MALDI-TOF MS and the Carba NP test has been evaluated. Bacterial identification was correct in 129 of the 130 isolates tested while the Carba NP detected 28 out of the 29 carbapenemase producers.
Keywords:
