Automatic Identification of MALDI-TOF MS Database Using Classical Bordetella Species Isolates

Table 1

The identification scores of 91 isolates of Bordetella species analyzed using the Bruker Daltonics database and our new database.

Genomospecies	MALDI-TOF identification using DB-5989MSP				MALDI-TOF identification using the implemented database
	>2.300	2.000-2.299	1.700-1.999	Total	>2.300	2.000-2.299	1.700-1.999	Total
B. pertussis	2	54	33	89	83	6	0	89
B. parapertussis	0	1	0	1	1	0	0	1
B. bronchiseptica	0	1	0	1	1	0	0	1

Scores of 0 to 3 (log10) were assigned according to spectral peak patterns as follows: >2.300, secure species identification; 2.000 to 2.299, secure genus identification; 1.700 to 1.999, probable genus identification; and <1.700, no reliable identification.
