FIG. 1 Identification of polymicrobial results displayed within the BioTyper 2.0 graphic view. The mass spectra shows the difference in peaks (presence or absence) and their intensity between the sample spectrum and those of bacteria identified at first proposals. The upper part of the figure within the inner windows shows the unknown spectrum containing perfectly matching peaks (0–200 p.p.m.) in green, imperfectly matching peaks (200–500 p.p.m.) in yellow, and non-matching peaks in red. The lower part (blue) shows the dedicated main spectrum included in the database.
