OBJECTIVE To evaluate the performance of matrix-assisted laser desorption ionization time of flight mass spectrometry(MALDI-TOF MS)in identification of common clinical Staphylococcus species.METHODS By means of MALDI-TOF MS,totally 151 strains of Staphylococcus spp that were isolated from 2011 to 2013were analyzed and compared,then the strains that were inconsistent with the identification results were finally identified by using the 16 SrRNA sequencing method,and the performance of MALDI-TOF MS to identify...
