Matrix-assisted laser desorption ionization-time of flight mass spectrometry can accurately differentiate Aeromonas dhakensis from A. hydrophila, A. caviae, and A. veronii

Among 217 Aeromonas isolates identified by sequencing analysis of their rpoB genes, the accuracy rates of identification of A. dhakensis, A. hydrophila, A. veronii, and A. caviae were 96.7%, 90.0%, 96.7%, and 100.0%, respectively, by the cluster analysis of spectra generated by matrix-assisted laser desorption ionization-time of flight mass spectrometry.
