Number of taxon-to-spectrum matches for a pure Shigella flexneri sample. MS/MS spectra that can be associated with peptides and proteins to a selection of taxa available from Ciccarelli et al. [20] were numbered. A key observation is that the number of taxon-to-spectrum matches attributed to taxa that are not in the sample is directly linked to the taxonomical proximity to Shigella flexneri
