Fig. 3. Dendrogram constructed from the specific matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS)-generated mass spectra of A. baumannii, A. nosocomialis, and A. pittii within the improved database (which includes the original Bruker database). The protein profiles from A. baumannii isolates formed a separate cluster. The A. baumannii protein profiles were more closely associated with those from A. nosocomialis than those from A. pittii. All relative distance values are normalized to a maximal value of 1,000.
