TABLE 2.
Performance of Vitek MS, Bruker Biotyper MS and Vitek-2 Compact systems compared with ITS gene sequencing for the identification of 164 C. guilliermondii isolates
| Identification system | No. (%) of isolates |
|||
|---|---|---|---|---|
| Correct identification to species level | Correct identification to genus level | No identification (invalid result) | Misidentification | |
| Vitek MS system | 152 (92.7) | 7 (4.3) | 3 (1.8) | 2 (1.2) |
| Bruker Biotyper MS system | 159 (97.0)a | 0 (0) | 5 (3.0) | 0 (0) |
| Vitek-2 Compact system | 25 (15.2) | 122 (74.4)b | 0 (0) | 17 (10.4)c |
a
130 isolates with identification scores of ≥2.0 and 29 isolates with identification scores of 1.7 to 1.99.
b
Low discrimination between C. famata and C. guilliermondii.
c
Misidentified as C. famata.
