Description	RATIONALE: Distinguishing between individual bacterial strains below the species level is a challenge to matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) bacterial profiling. We propose a quick method for improving strain differentiation of two Staphylococcus and one Bacillus species. METHODS: An alternative procedure to the extraction protocol recommended by Bruker Daltonics was developed. Ethanol-sterilized cells of six S. aureus and six S. haemolyticus strains were digested by trypsin using 2-min microwave irradiation and were then analyzed. Twenty-eight strains belonging to two ecotypes of B. subtilis were subjected to the same procedure to extend the scope of the method. RESULTS: S. aureus and S. haemolyticus strains, only partially distinguishable by the standard sample preparation procedure, were subjected to microwave-assisted tryptic digestion. The repeatability of the procedure was checked in three experiments accomplished at weekly intervals.
