TABLE 4.
Comparison of identification by MALDI-TOF MS with 23S rRNA gene sequencingc
| Identification by 23S rRNA sequence (no. of strains) | No. of isolates (relative %) identified by MALDI-TOF MS |
|
|---|---|---|
| Concordance | Discordance | |
| Species (45)a | 45 (100) | 0 (0) |
| Subspecies (40)b | 40 (100) | 0 (0) |
a
Identification of all 45 Francisella strains at the species level.
b
Identification of the subset of all 40 Francisella tularensis strains at the subspecies level.
c
The maximum log score achievable is 3.0. Log score values of ≥2.0 are rated as a correct identification of a strain at the species or subspecies level.
