Table 1 Reference strains tested by MALDI-TOF MS analysis. The two best matches obtained in the Biotyper were taken into account. For strains for which the first and second best match indicated the same species, only one result (with the highest log(score)) is shown in the table. A-U – symbols for reference strains used in Table 3 and in Figs. 1, 2, 3 and 4
