Special application of matrix-assisted laser desorption ionization time-of-flight mass spectrometry in clinical microbiological diagnostics

Abstract: A mikrobiológiai diagnosztika területén kevés technikai fejlesztés volt az elmúlt évtizedekben, amely olyan rohamos fejlődést hozott volna a baktériumok és gombák fajszintű (speciesszintű) identifi kálásában, mint a "matrix-assisted laser desorption ionization time-of-fl ight" tömegspektrometria. A klinikai mikrobiológiai gyakorlatban ennek jelentősége felbecsülhetetlen, hiszen a kórokozó ismerete jelentősen befolyásolja a terápiás választást még az antimikrobás szerrel szembeni rezisztencia meghatározása előt… Show more

“…Therefore, it is crucial to identify and differentiate the NAS species colonizing teat skin or inhabiting milk that cause IMI to understand their epidemiology and to evaluate the clinical relevance and feasibility of speciesspecific infection control measures (Zadoks and Watts, 2009). Furthermore, routine microbiological testing is important, because rapid and correct identification of mastitis-causing pathogens will influence the choice of antibiotic before the final determination of antibiotic resistance of the isolate (Nagy et al, 2014). For many years, the species identification of NAS relied on phenotypic characteristics, which is difficult, time-consuming, laborious, and often inaccurate (Watts et al, 1991;Vanderhaeghen et al, 2014).…”

“…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.…”

“…Latex agglutination-based rapid tests—aiming to identify the main pathogens of bacterial meningitis from the cerebrospinal fluid—were also performed. After 2013, several tertiary-care hospitals and specialized-care centers have introduced matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) into their diagnostic workflow [ 62 , 63 ].…”
