Figure 3

Heat map analysis of MS spectra of 48 V. cholerae isolates and one V. mimicus strain. Each isolate is represented by four spectra (horizontal lanes) obtained from four spots on the MALDI target. The color indicates the peak intensities according to the color scale (left bar). The spectra were divided into spectrogram groups (separated by red horizontal lines): 1, V. cholerae serogroup O139 (GT1); 2, V. cholerae serogroup O1 serotype Hikojima and Ogawa strains (GT1); 3, serogroup O1 serotype Inaba (GT2); 4, SLVs; 5, serogroup O1 serotype Ogawa (2x) and Inaba (1x) (GT3); 6 and 7, two pairs isolated from the Bug river in Poland (GT 4, GT5); 8, pair isolated in Norway (GT6); 10, V. mimicus.
