S. lugdunensis whole cell matrix-assisted laser desorption/ionisation time-of-flight MS fingerprint. Bacteria were covered with a layer of matrix (alpha-Cyano-4-hydroxy-cinnamic acid) and submitted for analysis. The proteomic fingerprint in the mass-to-charge ratio (Da) from 3000 Da to 15.000 Da was species specific and was matched to the Biotyper 2.0 database (Bruker Daltonics). Within a few minutes a highly accurate identification up to the species level was reported.
