  1. A log scale ≥ 2.0 for MALDI-TOF MS, the identificate rate above 94% for VITEK 2, and the similarity values with type strains above 99% were used as a determinant of correct identificatio to the species level
  2. aDifferent letters (A, B) within a row indicate significant differences (p < 0.01)
