TABLE 3.
Analysis of 20 discordant isolates
| Molecular identification at the species or group level (no. of isolates) | No. of isolates for which biochemical identification matched identification by:
|
||
|---|---|---|---|
| API system | Phoenix system | Neither | |
| Species ID | |||
| S. pyogenes (1) | 1 | ||
| S. sanguinis (2) | 2 | ||
| S. parasanguinis (2) | 2 | ||
| S. gordonii (2) | 1 | 1 | |
| S. mitis (1) | 1 | ||
| E. faecium (4) | 4 | ||
| E. faecalis (3) | 3 | ||
| Group ID | |||
| S. mitis group (5) | 4a | 4a | 1 |
a
Identification by the API and the Phoenix systems gave results that were concordant at the group level but discordant at the species level.
