“…inexpensive test to detect carbapenemase activity (Nordmann et al, 2012b;Dortet et al, 2012), but the use of MALDI-TOF MS for carbapenemase detection has been increasing (Hrabak et al, 2011(Hrabak et al, , 2012Kempf et al, 2012;Wang et al, 2013;Sauget et al, 2014;Johansson et al, 2014;Hoyos-Mallecot et al, 2014;Nagy et al, 2014;Knox et al, 2014;Hrabak, 2015). In this report, we used MALDI-TOF MS analysis to detect carbapenemase activity in a diverse panel of clinical isolates of Enterobacteriaceae spp., P. aeruginosa and A. baumannii that collectively express one of eight different carbapenemases, and compared the results against the use of the Carba-NP assay on selected isolates.…”
